Power-management application The catalog illustrates system-status monitoring, local/remote operation, programmable voltage/current settings, and event/data logging. Connected supplies retain their own permitted adjustment ranges and parallel-operation limits. Application interfaces and wiring Parameter Details Enabled connector functions For the listed C configurations: programmable relays, DIN, DOUT, the selected PMBus or CANBus interface and Ethernet. RS-485, RS-232, AIN and AOUT are marked non-functional in the application matrix; PMBus and CANBus are separate ordering configurations. Relay rating Platform provision: four user-programmable relay channels, rated 30 V / 1 A. Use only the application’s supported relay functions. Relay connector 12-pin DECA MX422-25412 or equivalent. Relays 1/2/3/4 use pin groups 1–3 / 4–6 / 7–9 / 10–12 respectively; each group is NO, NC, COM in ascending pin order. Digital I/O Five isolated open-collector digital inputs and five digital outputs, referenced to FG. DOUT maximum signal voltage is 5 V relative to FG. DIN open from FG or +5 V = logic 1; shorted to FG or 0 V = logic 0. DIN/DOUT connector pins Each 10-pin connector uses pins 1, 3, 5, 7 and 9 for channels 1–5; pins 2, 4, 6, 8 and 10 are FG. The catalog identifies HIROSE DF11-10 or equivalent connectors. Bus connector pins For the selected PMBus or CANBus paired RJ45 interface: pins 4/12 = remote ON/OFF CONTROL, 6/14 = SDA (PMBus) or CAN-H (CANBus), 7/15 = SCL (PMBus) or CAN-L (CANBus), 8/16 = FG. Pins 1, 2, 3, 5, 9, 10, 11 and 13 are NC. Bus signals are isolated with FG as reference; connect only the interface enabled by this application. Analog I/O availability The shared platform specification lists five 0–10 V analog outputs and five 0–10 V analog inputs with 12-bit resolution. These analog functions are marked non-functional for the listed C application configurations. Ethernet connector RJ45: pin 1 TX+, 2 TX−, 3 RX+, 6 RX−; pins 4, 5, 7 and 8 are FG. Do not confuse Ethernet with the physically similar PMBus/CANBus connectors. Communication address groups The C manual describes up to three ports, each with 64 unique device addresses. Displayed groups are 0–63, 64–127 and 128–191. PMBus configuration ports: JK51, JK900, JK901; CANBus configuration ports: JK52, JK600, JK601. Address each connected unit uniquely within its port and use the ports fitted to the selected configuration. Parallel-power limitation Communication address capacity is not a parallel-power rating. The catalog gives a 40-power-supply parallel example and mentions a possible 48; the C manual’s DRP-3200 example distinguishes 40 parallel supplies from communication with 48 devices. Confirm the actual power-supply system’s permitted parallel count before design. Bus termination For CANBus, the C manual recommends termination resistors at both the controller and power-supply ends to reduce signal reflection. Select termination according to the connected system’s instructions. Input, environment and standards Parameter Details Input voltage and frequency 85–264 VAC, 47–63 Hz; 120–370 VDC. Use the published operating range for the supplied unit; the AC connector labels do not establish a DC polarity assignment. Input current 0.6 A at 115 VAC; 0.4 A at 230 VAC. AC input connector Pin 1 = AC/N, pin 2 = AC/L, pin 3 = FG. Follow the input and grounding instructions for the supplied controller. Operating temperature −25°C to +60°C.

Unit mass 2160 g, catalog packing reference per unit (2.16 kg; 6 pieces / 14 kg / 2.91 CUFT). This is not a separately declared measured net mass. Manufacturer warranty reference The catalog states a five-year manufacturer warranty, subject to its applicable terms. Manufacturer installation and commissioning instructions Parameter Details Electrical connection Connect AC input pin 1 to neutral, pin 2 to line and pin 3 (FG) to protective earth. This Class I controller requires a reliable protective-earth connection. Installation environment Avoid locations with high moisture, high ambient temperature or direct sunlight. Protect the LCD from sharp tools. Have faults examined by a qualified technician; do not remove the controller case yourself. Bus configuration Assign a unique device address to each connected power supply within its communication port. Use the PMBus or CANbus connections for the supplied controller configuration. For CANbus, the manual recommends termination resistors at both the controller and power-supply ends. Addressing and parallel operation The CMU2C manual describes three independent ports with up to 64 addresses per port, displayed as 0–63, 64–127 and 128–191. These address ranges are not a parallel-power rating. Confirm the supported device count, firmware and parallel limits of the connected power-supply series before commissioning. Digital I/O limits Digital inputs and outputs are isolated open-collector signals referenced to FG. Digital outputs have a maximum signal voltage of 5 V. For digital inputs, an open input or +5 V is logic high; a connection to FG or 0 V is logic low. Logging and firmware Data and event logging require an installed 4–32 GB SDHC card. Follow the model-specific card-access instructions and refit the cover. The CMU2C manual also requires an installed SD card for online or offline firmware updates; select the correct firmware, schedule the update and follow the reboot procedure. Alarm indication and version The current catalog describes a steady red fault indication, while the CMU2C manual describes a flashing red alarm. Follow the indication guidance for the supplied controller version. Rack mounting Install the rack-mount version using M5 × 12 mm screws as shown in the dedicated mounting diagram. The standalone DIN-rail and desktop attachments do not apply to this version.

Input load curve The static-characteristics plot shows 100% load across the specified 180 to 264 VAC input range at 60 Hz; thermal and installation limits still apply. Voltage and Current Programming PV / PC selection CN1 pins 5 and 6 shorted selects PV (output-voltage programming); open selects PC (output-current programming). Factory setting is PV at maximum output voltage with a jumper cap fitted. Removing that jumper selects PC at the maximum constant-current setting. Built-in adjustment SVR2 sets output voltage or the constant-current point over 20% to 100% of the applicable maximum. Select PV or PC first. External programming input CN2 pin 5 is PV/PC+ and pin 6 is PV/PC-. Use the catalog DC-voltage input or a 10 V PWM signal at 500 Hz to 1 kHz. Typical port current is 100 uA. These are control inputs, not output-power terminals. External PV range 18 to 120 V maximum. The PV graph spans 1.5 to 10 V external DC input, or 15% to 100% PWM duty, and is marked non-linear. External PC range 2.4 to 30 A maximum in the model-specific range table. The PC graph spans 0.8 to 10 V external DC input, or 8% to 100% PWM duty, and is marked non-linear. PC operating area Programming current above the nominal 25 A requires lower output voltage and must remain inside the PDF operating area and the 3000 W power limit. It does not permit 30 A at the nominal 120 V. Recommended high-performance area The shaded PC-mode region on PDF page 38 includes 15 A at 120 V to 25 A at 120 V, then the 3000 W boundary to 30 A at 100 V; the shaded region converges to 30 A at 90 V. Use the complete I-V diagram for the intended operating point; the unshaded allowed area and shaded recommended area are different. Protection and Recovery Short circuit Output shuts down and latches off; re-power to recover. Over-current / overload The specification gives 105% to 120% of rated output power. With CN1 pins 5/6 shorted, the factory protection behavior is constant-current limiting followed by shutdown after 3 seconds; re-power to recover. With the jumper removed, protection is continuous constant-current limiting. This jumper also selects PV/PC mode. Over-voltage 127 to 150 V; output shuts down; re-power to recover. Over-temperature Output shuts down. It recovers automatically after the temperature falls, or by re-powering as stated in the catalog. Fan failure Fan-failure protection is listed; a steady red indicator identifies a fan fault. Keep the cooling path unobstructed. Remote Control, Auxiliary Supply and Alarms Remote ON/OFF pins CN1 pin 3 = RC; pin 1 = RCG. Use one complete connection circuit from PDF page 40. In examples 2.2(A) and 2.2(B), an open switch means output ON and a closed switch means OFF. Example 2.2(C) reverses that logic: closed = ON and open = OFF. Auxiliary supply 12 V at 0.4 A. CN2 pin 2 = 12V AUX+; pin 1 = 12V AUXG. The auxiliary output may be used with the catalog remote-control circuits. P OK relay contact CN1 pin 7 = P-OK; pin 9 = P-OK GND. Power OK is low (0.5 V maximum at 500 mA); power failure is high or open. An external voltage source and resistor are required; respect the 20 V and 500 mA limits and the 10 W relay-contact limit. P OK2 signal CN1 pin 2 = P-OK-2; pin 4 = P-OK-GND-2. The catalog labels this a TTL alarm and shows an open-collector circuit. Power OK is low (0.5 V maximum at 10 mA); power failure is high or open. Use an external voltage source and resistor, maximum 30 V and 10 mA. Parallel Operation Permitted arrangement Up to three CSP-3000 units with built-in active current sharing, using short, large-diameter output wiring. Connect like-polarity CS+ and CS- signals together; do not reverse them. Current-sharing pins CN1 pin 8 = CS+; pin 10 = CS-. Constant-voltage parallel mode Keep the difference between unit output voltages below 0.2 V, fine-tuned with SVR1. Maximum combined current = rated current per unit × number of units × 0.9. Below 50% rated current per unit × number of units, current sharing may not be fully balanced. PV and PC programming are unavailable in this mode. Constant-current parallel mode Each unit must carry no more than 90% of its rated power. PC can be used; PV is unavailable. Apply each unit's voltage/current operating area and all thermal limits. System power planning The family headline is up to 9000 W (2+1), but the detailed parallel-operation limits require the 0.9 factor or 90% per-unit power condition. Do not treat three 3000 W nameplates as an unrestricted 9000 W continuous installation. Cooling and Environment Cooling Forced air from built-in DC fans with fan-speed control; airflow runs from the fan end toward the terminal end as drawn. Conformal coating is listed for this catalog version. Operating temperature / derating -20 to +65°C. For horizontal mounting, the curve shows 100% load through +50°C, reducing to 50% load at +65°C. The upper ambient limit is not a full-load rating. Altitude derating Above 2000 m (6500 ft), the catalog specifies 5°C per 1000 m ambient derating for fan-cooled models such as CSP-3000.

MEAN WELL CSP-3000-250 is an enclosed, single-output AC/DC power supply rated at 250 V DC, 12 A and 3000 W. It combines active PFC, built-in fans, selectable voltage or current programming, remote ON/OFF, a 12 V auxiliary supply, alarm signals and active current sharing. Use the output-mode, operating-area and installation limits below for the intended load. Product Datasheet Download MEAN WELL CSP-3000 Datasheet (PDF) The CSP-3000 section is on PDF pages 35, 36, 37, 38, 39, 40, 41, 42, 43, 44. Refer to the complete mechanical drawings and notes when planning installation. Model and Output Specifications Complete model CSP-3000-250 Model code CSP is the series; 3000 identifies the 3000 W power class; 250 identifies the nominal output voltage in volts. Nominal DC output 250 V DC / 12 A / 3000 W Specified current range 0 to 12 A Constant-current region 125 to 250 V; use the model-specific PC-mode operating-area diagram and the 3000 W limit. Ripple and noise, maximum 1000 mVp-p. In PV mode, measured with 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 uF and 47 uF capacitors. Voltage tolerance / regulation Voltage tolerance ±1.0%, including setup, line and load regulation; line regulation ±0.5%; load regulation ±0.5%. Typical efficiency 92.5% at 230 VAC, rated load and 25°C, the standard catalog measurement conditions unless otherwise stated. Setup / rise / hold-up 1000 ms setup and 80 ms rise at 230 VAC and full load; typical hold-up time 10 ms at full load. Input and Power Factor Input range 180 to 264 VAC or 254 to 370 VDC; AC frequency 47 to 63 Hz. The catalog requires turning off the output when input is below 160 VAC. Power factor Built-in active PFC; typical PF ≥0.95 at 230 VAC and full load. Typical AC current 20 A at 180 VAC; 16 A at 230 VAC. Inrush / leakage Typical cold-start inrush 60 A at 230 VAC; leakage current <0.3 mA at 240 VAC. Input load curve The static-characteristics plot shows 100% load across the specified 180 to 264 VAC input range at 60 Hz; thermal and installation limits still apply. Voltage and Current Programming PV / PC selection CN1 pins 5 and 6 shorted selects PV (output-voltage programming); open selects PC (output-current programming). Factory setting is PV at maximum output voltage with a jumper cap fitted. Removing that jumper selects PC at the maximum constant-current setting. Built-in adjustment SVR2 sets output voltage or the constant-current point over 20% to 100% of the applicable maximum. Select PV or PC first. External programming input CN2 pin 5 is PV/PC+ and pin 6 is PV/PC-. Use the catalog DC-voltage input or a 10 V PWM signal at 500 Hz to 1 kHz. Typical port current is 100 uA. These are control inputs, not output-power terminals. External PV range 37.5 to 250 V maximum. The PV graph spans 1.5 to 10 V external DC input, or 15% to 100% PWM duty, and is marked non-linear. External PC range 1.4 to 17 A maximum in the model-specific range table. The PC graph spans 0.8 to 10 V external DC input, or 8% to 100% PWM duty, and is marked non-linear. PC operating area Programming current above the nominal 12 A requires lower output voltage and must remain inside the PDF operating area and the 3000 W power limit. It does not permit 17 A at the nominal 250 V. Recommended high-performance area The shaded PC-mode region on PDF page 38 includes 9 A at 250 V to 12 A at 250 V, then the 3000 W boundary to 17 A at 176.5 V; the diagram extends down to 125 V. Use the complete I-V diagram for the intended operating point; the unshaded allowed area and shaded recommended area are different. Protection and Recovery Short circuit Output shuts down and latches off; re-power to recover. Over-current / overload The specification gives 105% to 120% of rated output power. With CN1 pins 5/6 shorted, the factory protection behavior is constant-current limiting followed by shutdown after 3 seconds; re-power to recover. With the jumper removed, protection is continuous constant-current limiting. This jumper also selects PV/PC mode. Over-voltage 265 to 315 V; output shuts down; re-power to recover. Over-temperature Output shuts down. It recovers automatically after the temperature falls, or by re-powering as stated in the catalog. Fan failure Fan-failure protection is listed; a steady red indicator identifies a fan fault. Keep the cooling path unobstructed. Remote Control, Auxiliary Supply and Alarms Remote ON/OFF pins CN1 pin 3 = RC; pin 1 = RCG. Use one complete connection circuit from PDF page 40. In examples 2.2(A) and 2.2(B), an open switch means output ON and a closed switch means OFF. Example 2.2(C) reverses that logic: closed = ON and open = OFF. Auxiliary supply 12 V at 0.4 A. CN2 pin 2 = 12V AUX+; pin 1 = 12V AUXG. The auxiliary output may be used with the catalog remote-control circuits. P OK relay contact CN1 pin 7 = P-OK; pin 9 = P-OK GND. Power OK is low (0.5 V maximum at 500 mA); power failure is high or open. An external voltage source and resistor are required; respect the 20 V and 500 mA limits and the 10 W relay-contact limit. P OK2 signal CN1 pin 2 = P-OK-2; pin 4 = P-OK-GND-2. The catalog labels this a TTL alarm and shows an open-collector circuit. Power OK is low (0.5 V maximum at 10 mA); power failure is high or open. Use an external voltage source and resistor, maximum 30 V and 10 mA. Parallel Operation Permitted arrangement Up to three CSP-3000 units with built-in active current sharing, using short, large-diameter output wiring. Connect like-polarity CS+ and CS- signals together; do not reverse them. Current-sharing pins CN1 pin 8 = CS+; pin 10 = CS-. Constant-voltage parallel mode Keep the difference between unit output voltages below 0.2 V, fine-tuned with SVR1. Maximum combined current = rated current per unit × number of units × 0.9. Below 50% rated current per unit × number of units, current sharing may not be fully balanced. PV and PC programming are unavailable in this mode. Constant-current parallel mode Each unit must carry no more than 90% of its rated power. PC can be used; PV is unavailable. Apply each unit's voltage/current operating area and all thermal limits.

MEAN WELL CSP-3000 series: programmable high-voltage AC/DC power supply - CSP-3000-400
MEAN WELL CSP-3000-400 is an enclosed, single-output AC/DC power supply rated at 400 V DC, 7.5 A and 3000 W. It combines active PFC, built-in fans, selectable voltage or current programming, remote ON/OFF, a 12 V auxiliary supply, alarm signals and active current sharing. Use the output-mode, operating-area and installation limits below for the intended load. Product Datasheet Download MEAN WELL CSP-3000 Datasheet (PDF) The CSP-3000 section is on PDF pages 35, 36, 37, 38, 39, 40, 41, 42, 43, 44. Refer to the complete mechanical drawings and notes when planning installation. Model and Output Specifications Complete model CSP-3000-400 Model code CSP is the series; 3000 identifies the 3000 W power class; 400 identifies the nominal output voltage in volts. Nominal DC output 400 V DC / 7.5 A / 3000 W Specified current range 0 to 7.5 A Constant-current region 200 to 400 V; use the model-specific PC-mode operating-area diagram and the 3000 W limit. Ripple and noise, maximum 1200 mVp-p. In PV mode, measured with 20 MHz bandwidth using a 12-inch twisted pair terminated with parallel 0.1 uF and 47 uF capacitors. Voltage tolerance / regulation Voltage tolerance ±1.0%, including setup, line and load regulation; line regulation ±0.5%; load regulation ±0.5%. Typical efficiency 93% at 230 VAC, rated load and 25°C, the standard catalog measurement conditions unless otherwise stated. Setup / rise / hold-up 1000 ms setup and 80 ms rise at 230 VAC and full load; typical hold-up time 10 ms at full load. Input and Power Factor Input range 180 to 264 VAC or 254 to 370 VDC; AC frequency 47 to 63 Hz. The catalog requires turning off the output when input is below 160 VAC. Power factor Built-in active PFC; typical PF ≥0.95 at 230 VAC and full load. Typical AC current 20 A at 180 VAC; 16 A at 230 VAC. Inrush / leakage Typical cold-start inrush 60 A at 230 VAC; leakage current <0.3 mA at 240 VAC. Input load curve The static-characteristics plot shows 100% load across the specified 180 to 264 VAC input range at 60 Hz; thermal and installation limits still apply. Voltage and Current Programming PV / PC selection CN1 pins 5 and 6 shorted selects PV (output-voltage programming); open selects PC (output-current programming). Factory setting is PV at maximum output voltage with a jumper cap fitted. Removing that jumper selects PC at the maximum constant-current setting. Built-in adjustment SVR2 sets output voltage or the constant-current point over 20% to 100% of the applicable maximum. Select PV or PC first. External programming input CN2 pin 5 is PV/PC+ and pin 6 is PV/PC-. Use the catalog DC-voltage input or a 10 V PWM signal at 500 Hz to 1 kHz. Typical port current is 100 uA. These are control inputs, not output-power terminals. External PV range 60 to 400 V maximum. The PV graph spans 1.5 to 10 V external DC input, or 15% to 100% PWM duty, and is marked non-linear. External PC range 0.8 to 10 A maximum in the model-specific range table. The PC graph spans 0.8 to 10 V external DC input, or 8% to 100% PWM duty, and is marked non-linear. PC operating area Programming current above the nominal 7.5 A requires lower output voltage and must remain inside the PDF operating area and the 3000 W power limit. It does not permit 10 A at the nominal 400 V. Recommended high-performance area The shaded PC-mode region on PDF page 38 includes 5.25 A at 400 V to 7.5 A at 400 V, then the 3000 W boundary to 10 A at 300 V; the diagram extends down to 200 V. Use the complete I-V diagram for the intended operating point; the unshaded allowed area and shaded recommended area are different. Protection and Recovery Short circuit Output shuts down and latches off; re-power to recover. Over-current / overload The specification gives 105% to 120% of rated output power. With CN1 pins 5/6 shorted, the factory protection behavior is constant-current limiting followed by shutdown after 3 seconds; re-power to recover. With the jumper removed, protection is continuous constant-current limiting. This jumper also selects PV/PC mode. Over-voltage 420 to 500 V; output shuts down; re-power to recover. Over-temperature Output shuts down. It recovers automatically after the temperature falls, or by re-powering as stated in the catalog. Fan failure Fan-failure protection is listed; a steady red indicator identifies a fan fault. Keep the cooling path unobstructed. Remote Control, Auxiliary Supply and Alarms Remote ON/OFF pins CN1 pin 3 = RC; pin 1 = RCG. Use one complete connection circuit from PDF page 40. In examples 2.2(A) and 2.2(B), an open switch means output ON and a closed switch means OFF. Example 2.2(C) reverses that logic: closed = ON and open = OFF. Auxiliary supply 12 V at 0.4 A. CN2 pin 2 = 12V AUX+; pin 1 = 12V AUXG. The auxiliary output may be used with the catalog remote-control circuits. P OK relay contact CN1 pin 7 = P-OK; pin 9 = P-OK GND. Power OK is low (0.5 V maximum at 500 mA); power failure is high or open. An external voltage source and resistor are required; respect the 20 V and 500 mA limits and the 10 W relay-contact limit. P OK2 signal CN1 pin 2 = P-OK-2; pin 4 = P-OK-GND-2. The catalog labels this a TTL alarm and shows an open-collector circuit. Power OK is low (0.5 V maximum at 10 mA); power failure is high or open. Use an external voltage source and resistor, maximum 30 V and 10 mA. Parallel Operation Permitted arrangement Up to three CSP-3000 units with built-in active current sharing, using short, large-diameter output wiring. Connect like-polarity CS+ and CS- signals together; do not reverse them. Current-sharing pins CN1 pin 8 = CS+; pin 10 = CS-. Constant-voltage parallel mode Keep the difference between unit output voltages below 0.2 V, fine-tuned with SVR1. Maximum combined current = rated current per unit × number of units × 0.9. Below 50% rated current per unit × number of units, current sharing may not be fully balanced. PV and PC programming are unavailable in this mode. Constant-current parallel mode Each unit must carry no more than 90% of its rated power. PC can be used; PV is unavailable. Apply each unit's voltage/current operating area and all thermal limits. System power planning The family headline is up to 9000 W (2+1), but the detailed parallel-operation limits require the 0.9 factor or 90% per-unit power condition.

Terminal preparation and cover Strip 10 mm at TB1 and TB2 and use a 3 mm slotted screwdriver; the suggested push-down force is 3-4 kp (6.61-8.81 lbf). The 4.6 kgf-cm (4 lb-in) tightening recommendation with a 5 mm Phillips screwdriver applies to the blue covers, not to the push terminals. DALI cable limit Limit the voltage drop between the converter and DALI controller to 2 V. The manual gives a maximum cable length of 300 m when using 1.5 mm2 cable. Relay load selection Use an additional magnetic switch when the total input current of the selected LED power supplies exceeds 8 A or their inrush current exceeds 50 A. This selection condition does not turn the relay contact rating into a permissible rating for every LED-driver load. Circuit-breaker example For standard DAP-04 at 230 VAC, the manual lists maximum quantities of 10, 16, 17 and 27 on ABB S201 B10, B16, C10 and C16 breakers respectively. These manufacturer-specific calculated examples do not apply to every breaker or to DAP-04-S01 without confirmation.

MEAN WELL DBR-3200-24 is a 24 V-class rack-mountable front-end battery charger with 110 A constant-current charging, a default 28.8 V boost stage and 27.6 V float stage. This model uses PMBus; select the charging curve and current for the battery and apply input and temperature derating. Product Datasheet Download MEAN WELL DBR-3200 Datasheet (PDF) The DBR-3200 section is on PDF pages 1, 2, 3, 4, 5, 6. Refer to the complete mechanical drawings and notes when planning installation. Model and charging application Full model DBR-3200-24 Product type DBR-3200 1U rack-mountable front-end battery charger Voltage designation 24 V battery class; use the actual boost and float voltages below Communication option PMBus standard model with no communication suffix Catalogue power class 3200 W Suitable battery types include lead-acid flooded, Gel and AGM, plus Li-ion lithium-iron and lithium-manganese batteries. Configure the charging curve and current for the specific battery manufacturer requirements before connection. Applications include battery backup, charging systems and central charging infrastructure. The catalogue describes a 1U low-profile design with power density up to 37 W/in³, active PFC and active inrush limiting. Charging output and battery selection Default boost charge voltage 28.8 V Default float charge voltage 27.6 V Rated charging current 110 A Voltage adjustment by SVR 23.5 to 30 V Recommended battery capacity 330 to 1000 Ah Battery back-leakage current <1.5 mA Typical efficiency 93.5% The default charging sequence is constant current, constant voltage, then float. The illustrated transition from constant voltage to float occurs when current falls to 10% of the constant-current level. Use the recommended battery-capacity range and suitable current settings. A substantially smaller battery requiring a low charging-current setting can experience higher current ripple. The series power-class designation does not override voltage, current or derating limits. Embedded charging curves and programming Default, programmable boost / float 28.8 V / 27.6 V Gel boost / float 28 V / 27.2 V Flooded boost / float 28.4 V / 26.8 V AGM boost / float 29 V / 27 V These embedded presets use 110 A as the default constant-current setting. Select the correct battery curve; the model suffix identifies communication, not a different default battery voltage. The PMBus version supports PMBus Rev. 1.1 at up to 100 kHz for reading information, monitoring status and adjusting output settings. Charging-curve parameters can be configured using the separately required MEAN WELL SBP-001 smart battery charging programmer and a personal computer. Refer to the installation manual for two-stage operation, stage timeouts and alternative curves. Input, conversion and protection AC input range 90–264 VAC DC input range 127–370 VDC Input frequency 47–63 Hz Typical power factor 0.97 at 230 VAC and full load Typical AC current 17 A at 230 VAC Typical cold-start inrush 55 A at 230 VAC AC leakage current <1.5 mA at 230 VAC Overvoltage protection 31.5 to 37.5 V; output shutdown; reapply input power to recover Overtemperature protection Output shutdown; automatic recovery after the temperature decreases Protection features also cover battery undervoltage, no battery connection and short circuit. The status indications identify the relevant operating or fault condition; follow the installation manual when diagnosing a trip. The 60 Hz input curve permits 50% load at 90 VAC, rising to 100% at 180 VAC; 100% is shown from 180 to 264 VAC. Apply the temperature derating at the same time. The converter block diagram identifies 110 kHz PFC and 90 kHz PWM switching. Voltage and current programming PV adjusts output over 75–125% of nominal voltage: 18–30 V for this voltage class. Connect the external control between CN1 pin 27 (PV) and pin 29 (−V signal). The PV graph shows 24 V from 0 V control to just below 0.4 V, a transition to 18 V at 0.4 V, a low plateau through 1 V, and 30 V at 4.7 V through 5 V. The graph is labelled non-linear; use its plotted anchors and the installation instructions rather than assuming one linear conversion. PC adjusts output current over 20–100% of rated current. Connect the external control between CN1 pin 26 (PC) and pin 29 (−V signal). The graph shows 20% from 0.4 to 1 V control, increasing to 100% at 4.7 V and holding through 5 V; it is labelled non-linear. Temperature compensation and remote control Temperature compensation is −3 mV/°C per battery cell; this voltage class uses 12 cells. Place the NTC sensor against the battery or nearby. Normal charger operation is possible without the temperature sensor. The DBR temperature-sense connections are CN1 pin 30 (RTH+) and pin 31 (RTH−). Select the sensor and wiring in accordance with the DBR installation instructions. Remote control: connect CN1 pin 17 to +5V-AUX pin 13 for ON; leave the contact open for OFF. ON corresponds to 4.5–5.5 V and OFF to −0.5 to +0.5 V. Maximum remote-control input is 5.5 V. Auxiliary outputs remain available independently of remote ON-OFF. Rack integration and parallel control Compatible rack option DHP-1UT, ordered separately Rack-system capability The DBR series specifies up to 12800 W in one 19-inch rack shelf, using the applicable rack and module configuration Hot-swap provision Built-in ORing FET supports hot swapping in the documented rack arrangement A single DBR-3200 is one front-end module, not a complete populated rack. Select the DHP-1UT configuration, system wiring and module count to meet the required output, and observe the rack installation instructions. CN1 pin 24 is DB and pin 25 is DA for differential parallel control. These signals are non-isolated and reference −V signal. Rack-system ratings do not increase the charging-current rating of this individual module.

MEAN WELL DBR-3200-24CAN is a 24 V-class rack-mountable front-end battery charger with 110 A constant-current charging, a default 28.8 V boost stage and 27.6 V float stage. This model uses CANBus; select the charging curve and current for the battery and apply input and temperature derating. Product Datasheet Download MEAN WELL DBR-3200 Datasheet (PDF) The DBR-3200 section is on PDF pages 1, 2, 3, 4, 5, 6. Refer to the complete mechanical drawings and notes when planning installation. Model and charging application Full model DBR-3200-24CAN Product type DBR-3200 1U rack-mountable front-end battery charger Voltage designation 24 V battery class; use the actual boost and float voltages below Communication option CANBus fitted by request, identified by the CAN suffix Catalogue power class 3200 W Suitable battery types include lead-acid flooded, Gel and AGM, plus Li-ion lithium-iron and lithium-manganese batteries. Configure the charging curve and current for the specific battery manufacturer requirements before connection. Applications include battery backup, charging systems and central charging infrastructure. The catalogue describes a 1U low-profile design with power density up to 37 W/in³, active PFC and active inrush limiting. Charging output and battery selection Default boost charge voltage 28.8 V Default float charge voltage 27.6 V Rated charging current 110 A Voltage adjustment by SVR 23.5 to 30 V Recommended battery capacity 330 to 1000 Ah Battery back-leakage current <1.5 mA Typical efficiency 93.5% The default charging sequence is constant current, constant voltage, then float. The illustrated transition from constant voltage to float occurs when current falls to 10% of the constant-current level. Use the recommended battery-capacity range and suitable current settings. A substantially smaller battery requiring a low charging-current setting can experience higher current ripple. The series power-class designation does not override voltage, current or derating limits. Embedded charging curves and programming Default, programmable boost / float 28.8 V / 27.6 V Gel boost / float 28 V / 27.2 V Flooded boost / float 28.4 V / 26.8 V AGM boost / float 29 V / 27 V These embedded presets use 110 A as the default constant-current setting. Select the correct battery curve; the model suffix identifies communication, not a different default battery voltage. This CAN-suffix version uses CANBus; select the CANBus installation and configuration instructions for this unit. Charging-curve parameters can be configured using the separately required MEAN WELL SBP-001 smart battery charging programmer and a personal computer. Refer to the installation manual for two-stage operation, stage timeouts and alternative curves. Input, conversion and protection AC input range 90–264 VAC DC input range 127–370 VDC Input frequency 47–63 Hz Typical power factor 0.97 at 230 VAC and full load Typical AC current 17 A at 230 VAC Typical cold-start inrush 55 A at 230 VAC AC leakage current <1.5 mA at 230 VAC Overvoltage protection 31.5 to 37.5 V; output shutdown; reapply input power to recover Overtemperature protection Output shutdown; automatic recovery after the temperature decreases Protection features also cover battery undervoltage, no battery connection and short circuit. The status indications identify the relevant operating or fault condition; follow the installation manual when diagnosing a trip. The 60 Hz input curve permits 50% load at 90 VAC, rising to 100% at 180 VAC; 100% is shown from 180 to 264 VAC. Apply the temperature derating at the same time. The converter block diagram identifies 110 kHz PFC and 90 kHz PWM switching. Voltage and current programming PV adjusts output over 75–125% of nominal voltage: 18–30 V for this voltage class. Connect the external control between CN1 pin 27 (PV) and pin 29 (−V signal). The PV graph shows 24 V from 0 V control to just below 0.4 V, a transition to 18 V at 0.4 V, a low plateau through 1 V, and 30 V at 4.7 V through 5 V. The graph is labelled non-linear; use its plotted anchors and the installation instructions rather than assuming one linear conversion. PC adjusts output current over 20–100% of rated current. Connect the external control between CN1 pin 26 (PC) and pin 29 (−V signal). The graph shows 20% from 0.4 to 1 V control, increasing to 100% at 4.7 V and holding through 5 V; it is labelled non-linear. Temperature compensation and remote control Temperature compensation is −3 mV/°C per battery cell; this voltage class uses 12 cells. Place the NTC sensor against the battery or nearby. Normal charger operation is possible without the temperature sensor. The DBR temperature-sense connections are CN1 pin 30 (RTH+) and pin 31 (RTH−). Select the sensor and wiring in accordance with the DBR installation instructions. Remote control: connect CN1 pin 17 to +5V-AUX pin 13 for ON; leave the contact open for OFF. ON corresponds to 4.5–5.5 V and OFF to −0.5 to +0.5 V. Maximum remote-control input is 5.5 V. Auxiliary outputs remain available independently of remote ON-OFF. Rack integration and parallel control Compatible rack option DHP-1UT, ordered separately Rack-system capability The DBR series specifies up to 12800 W in one 19-inch rack shelf, using the applicable rack and module configuration Hot-swap provision Built-in ORing FET supports hot swapping in the documented rack arrangement A single DBR-3200 is one front-end module, not a complete populated rack. Select the DHP-1UT configuration, system wiring and module count to meet the required output, and observe the rack installation instructions. CN1 pin 24 is DB and pin 25 is DA for differential parallel control. These signals are non-isolated and reference −V signal.

The converter block diagram identifies 110 kHz PFC and 90 kHz PWM switching. Voltage and current programming PV adjusts output over 75–125% of nominal voltage: 36–60 V for this voltage class. Connect the external control between CN1 pin 27 (PV) and pin 29 (−V signal). The PV graph shows 48 V from 0 V control to just below 0.4 V, a transition to 36 V at 0.4 V, a low plateau through 1 V, and 60 V at 4.7 V through 5 V. The graph is labelled non-linear; use its plotted anchors and the installation instructions rather than assuming one linear conversion. PC adjusts output current over 20–100% of rated current. Connect the external control between CN1 pin 26 (PC) and pin 29 (−V signal). The graph shows 20% from 0.4 to 1 V control, increasing to 100% at 4.7 V and holding through 5 V; it is labelled non-linear. Temperature compensation and remote control Temperature compensation is −3 mV/°C per battery cell; this voltage class uses 24 cells. Place the NTC sensor against the battery or nearby. Normal charger operation is possible without the temperature sensor. The DBR temperature-sense connections are CN1 pin 30 (RTH+) and pin 31 (RTH−). Select the sensor and wiring in accordance with the DBR installation instructions. Remote control: connect CN1 pin 17 to +5V-AUX pin 13 for ON; leave the contact open for OFF. ON corresponds to 4.5–5.5 V and OFF to −0.5 to +0.5 V. Maximum remote-control input is 5.5 V. Auxiliary outputs remain available independently of remote ON-OFF. Rack integration and parallel control Compatible rack option DHP-1UT, ordered separately Rack-system capability The DBR series specifies up to 12800 W in one 19-inch rack shelf, using the applicable rack and module configuration Hot-swap provision Built-in ORing FET supports hot swapping in the documented rack arrangement A single DBR-3200 is one front-end module, not a complete populated rack.

The 12 V and 5 V auxiliary specifications are ±10%, with maximum ripple of 450 mVp-p and 150 mVp-p respectively. CN1 pin 18 DC-OK is high (3.5–5.5 V) when output is at or below 32 V ±1 V, and low (−0.5 to +0.5 V) when output is at or above that threshold; it is associated with battery-low protection. Pin 19 AC-OK is high at input of at least 87 Vrms and low at input of 75 Vrms or less. Pin 16 T-ALARM is high on a temperature alarm or fan failure and low when temperature and fan operation are normal. The alarm outputs are output-only, isolated signals referenced to GND-AUX, with a 10 mA maximum sourcing current and low level of −0.5 to +0.5 V. Communication and remote ON-OFF are also isolated and reference GND-AUX. D0, address lines, DB/DA and PC/PV are non-isolated and reference −V signal. Use the connector orientation and numbered positions in the complete drawing. The mating housing is a component reference; it is not stated to be included with each charger.

The converter block diagram identifies 110 kHz PFC and 90 kHz PWM switching. Voltage and current programming PV adjusts output over 75–125% of nominal voltage: 18–30 V for this voltage class. Connect the external control between CN1 pin 12 (PV) and pin 14 (−V signal). The PV graph shows 24 V from 0 V control to just below 0.4 V, a transition to 18 V at 0.4 V, a low plateau through 1 V, and 30 V at 4.7 V through 5 V. The graph is labelled non-linear; use its plotted anchors and the installation instructions rather than assuming one linear conversion. PC adjusts output current over 20–100% of rated current.

Temperature compensation and remote control Temperature compensation is −3 mV/°C per battery cell; this voltage class uses 12 cells. Place the NTC sensor against the battery or nearby. Normal charger operation is possible without the temperature sensor. DBU includes a 5 kΩ NTC sensor. Connect RTH+ to CN1 pin 15 and RTH− to pin 16. In a parallel installation, interconnect every unit’s RTH+ and RTH− terminals respectively even when temperature compensation is not required; attach the sensor to this common pair when used. Remote control: connect CN1 pin 4 to +5V-AUX pin 3 for ON; leave the contact open for OFF. ON corresponds to 4.5–5.5 V and OFF to −0.5 to +0.5 V. Maximum remote-control input is 5.5 V. Auxiliary outputs remain available independently of remote ON-OFF. Parallel operation Use up to two DBU-3200 units in parallel. Set their output voltages within less than 0.2 V of one another, and use short, large-section output wiring. The parallel current limit is rated current per unit × number of units × 0.9; for two of this model the resulting limit is 198.0 A. At less than 5% of the total rated output current, current sharing can become unbalanced. Interconnect DA, DB and −V signal between units through CN500. Use twisted pairs when the control wires are long. For one unit, CN500 is not connected and SW1 is ON; for two units, connect CN500 and keep the two units’ SW1 terminations ON as shown. Interconnect RTH+ and RTH− as specified in the temperature-compensation instructions. The built-in ORing FET supports the documented parallel arrangement.

MEAN WELL DBU-3200 series: Programmable Battery Charger - DBU-3200-48
MEAN WELL DBU-3200-48 is a 48 V-class programmable battery charger with 55 A constant-current charging, a default 57.6 V boost stage and 55.2 V float stage. This model uses PMBus; select the charging curve and current for the battery and apply input and temperature derating. Product Datasheet Download MEAN WELL DBU-3200 Datasheet (PDF) The DBU-3200 section is on PDF pages 15, 16, 17, 18, 19, 20, 21, 22. Refer to the complete mechanical drawings and notes when planning installation. Model and charging application Full model DBU-3200-48 Product type DBU-3200 1U enclosed programmable battery charger Voltage designation 48 V battery class; use the actual boost and float voltages below Communication option PMBus standard model with no communication suffix Catalogue power class 3200 W Suitable battery types include lead-acid flooded, Gel and AGM, plus Li-ion lithium-iron and lithium-manganese batteries. Configure the charging curve and current for the specific battery manufacturer requirements before connection. Applications include battery backup, charging systems and central charging infrastructure. The catalogue describes a 1U low-profile design with power density up to 37 W/in³, active PFC and active inrush limiting. Charging output and battery selection Default boost charge voltage 57.6 V Default float charge voltage 55.2 V Rated charging current 55 A Voltage adjustment by SVR 47.5 to 58.8 V Recommended battery capacity 180 to 550 Ah Battery back-leakage current 1.5 mA typical Typical efficiency 94.5% The default charging sequence is constant current, constant voltage, then float. The illustrated transition from constant voltage to float occurs when current falls to 10% of the constant-current level. Use the recommended battery-capacity range and suitable current settings. A substantially smaller battery requiring a low charging-current setting can experience higher current ripple. The series power-class designation does not override voltage, current or derating limits. Embedded charging curves and programming Default, programmable boost / float 57.6 V / 55.2 V Gel boost / float 56 V / 54.4 V Flooded boost / float 56.8 V / 53.6 V AGM boost / float 58 V / 54 V These embedded presets use 55 A as the default constant-current setting. Select the correct battery curve; the model suffix identifies communication, not a different default battery voltage. The PMBus version supports PMBus Rev. 1.1 at up to 100 kHz for reading information, monitoring status and adjusting output settings. Charging-curve parameters can be configured using the separately required MEAN WELL SBP-001 smart battery charging programmer and a personal computer. Refer to the installation manual for two-stage operation, stage timeouts and alternative curves. Input, conversion and protection AC input range 90–264 VAC DC input range 127–370 VDC Input frequency 47–63 Hz Typical power factor 0.97 at 230 VAC and full load Typical AC current 17 A at 230 VAC Typical cold-start inrush 55 A at 230 VAC AC leakage current <2 mA at 230 VAC Overvoltage protection 63 to 75 V; output shutdown; reapply input power to recover Overtemperature protection Output shutdown; automatic recovery after the temperature decreases Protection features also cover battery undervoltage, no battery connection and short circuit. The status indications identify the relevant operating or fault condition; follow the installation manual when diagnosing a trip. The 60 Hz input curve permits 50% load at 90 VAC, rising to 100% at 180 VAC; 100% is shown from 180 to 264 VAC. Apply the temperature derating at the same time. The converter block diagram identifies 110 kHz PFC and 90 kHz PWM switching. Voltage and current programming PV adjusts output over 75–125% of nominal voltage: 36–60 V for this voltage class. Connect the external control between CN1 pin 12 (PV) and pin 14 (−V signal). The PV graph shows 48 V from 0 V control to just below 0.4 V, a transition to 36 V at 0.4 V, a low plateau through 1 V, and 60 V at 4.7 V through 5 V. The graph is labelled non-linear; use its plotted anchors and the installation instructions rather than assuming one linear conversion. PC adjusts output current over 20–100% of rated current. Connect the external control between CN1 pin 11 (PC) and pin 14 (−V signal). The graph shows 20% from 0.4 to 1 V control, increasing to 100% at 4.7 V and holding through 5 V; it is labelled non-linear. Temperature compensation and remote control Temperature compensation is −3 mV/°C per battery cell; this voltage class uses 24 cells. Place the NTC sensor against the battery or nearby. Normal charger operation is possible without the temperature sensor. DBU includes a 5 kΩ NTC sensor. Connect RTH+ to CN1 pin 15 and RTH− to pin 16. In a parallel installation, interconnect every unit’s RTH+ and RTH− terminals respectively even when temperature compensation is not required; attach the sensor to this common pair when used. Remote control: connect CN1 pin 4 to +5V-AUX pin 3 for ON; leave the contact open for OFF. ON corresponds to 4.5–5.5 V and OFF to −0.5 to +0.5 V. Maximum remote-control input is 5.5 V. Auxiliary outputs remain available independently of remote ON-OFF. Parallel operation Use up to two DBU-3200 units in parallel. Set their output voltages within less than 0.2 V of one another, and use short, large-section output wiring. The parallel current limit is rated current per unit × number of units × 0.9; for two of this model the resulting limit is 99.0 A. At less than 5% of the total rated output current, current sharing can become unbalanced. Interconnect DA, DB and −V signal between units through CN500. Use twisted pairs when the control wires are long. For one unit, CN500 is not connected and SW1 is ON; for two units, connect CN500 and keep the two units’ SW1 terminations ON as shown. Interconnect RTH+ and RTH− as specified in the temperature-compensation instructions. The built-in ORing FET supports the documented parallel arrangement. Keep both units within their input, thermal and charging limits.

MEAN WELL DBUF20 series: DIN Rail Capacitor Buffer Module - DBUF20-24
MEAN WELL DBUF20-24 is a DIN rail electrolytic-capacitor buffer module for regulated 24 VDC systems, with a maximum buffer output current of 20 A. At 22 VDC and 20 A it provides 350 ms typical and 250 ms minimum buffering. It supports selectable fixed or dynamic trigger thresholds and status monitoring; duration depends on the load and operating conditions. Product Datasheet Download MEAN WELL DBUF20 Datasheet (PDF) The DBUF20 section is on PDF pages 1, 2, 3, 4, 5, 6, 7. Refer to the complete mechanical drawings and notes when planning installation. Model and Operating Principle Complete model DBUF20-24 Product type DIN rail buffer module for a regulated 24 VDC power supply. Energy is stored in electrolytic capacitors instead of lead-acid batteries. Model code DBUF identifies the DIN rail buffer family; 20 is the 20 A maximum buffer output; 24 is the nominal system voltage. Use Supplementary short-duration support for industrial controls, semiconductor fabrication equipment, factory automation and electromechanical apparatus. The module charges from an existing DC supply and releases stored energy when the selected voltage threshold is reached. It is not an AC-input power supply or a battery UPS with unlimited hold-up time. Charging and DC Buffer Ratings Nominal system voltage 24 VDC. Charging voltage 23–30 VDC. Charging / standby current 900 mA maximum during charging; 100 mA maximum in standby. Allow for this additional demand when sizing the upstream supply. Charging time 15 s typical; 25 s maximum. Buffer operating range 22–29 VDC. Fixed mode uses 22 VDC; dynamic mode follows the Vin−1 V setting described below. Maximum buffer current 20 A per DBUF20-24, subject to the finite buffering time and installation conditions. Buffer time at 20 A At 22 VDC: 350 ms typical; 250 ms minimum. Buffer time at 10 A At 22 VDC: 700 ms typical; 500 ms minimum. Buffer time at 0.1 A At 22 VDC: 45 s typical; 30 s minimum. Additional curve reference The typical 22 VDC buffering curve marks approximately 1.4 s at 5 A. Use the complete curve for intermediate loads; do not treat a typical curve value as a guaranteed minimum. Ripple and noise, maximum 200 mVp-p. Measured at 20 MHz bandwidth using a 12-inch twisted pair terminated by parallel 0.1 µF and 47 µF capacitors. Charging and buffering have different voltage ranges. All three tabulated buffering cases apply to this same complete model; they are operating points, not separate output-channel or power-supply variants. Mode Selector and Status Indication Fixed mode — factory setting With the switch at Fix 22Vdc, buffering starts when terminal voltage falls below 22 VDC. Dynamic mode With the switch at Vin−1Vdc, buffering starts when the input terminal voltage decreases by 1 VDC. LED continuously on Ready: the capacitors are fully charged. LED off The capacitors are discharged. LED flashing at 1 Hz The capacitors are charging. LED flashing at 10 Hz The module is buffering and its capacitors are discharging. The operating diagram shows charging, standby and buffer states separately. After the upstream supply loses AC input, its own hold-up interval precedes the module’s illustrated buffering interval. Control and Monitoring Signals Signal supply +Vs 10–35 VDC / 10 mA as specified. Supply +Vs from the module’s +V or from an external voltage source using the corresponding application wiring. Inhibit input I Buffer module ON when +Vs−V(I) <6 VDC; buffer module OFF when +Vs−V(I) >10 VDC. Maximum: 35 VDC / 4 mA. The intermediate region is not assigned a guaranteed state. Ready output R Charged-ready state: V(R) >+Vs−2 VDC. Unready state: V(R) <1 VDC. Maximum: 35 VDC / 10 mA. Buffering output B Buffering state: V(B) >+Vs−2 VDC. Other modes: V(B) <1 VDC. Maximum: 35 VDC / 10 mA. Signal interface The block and signal diagrams show optocouplers for I, R and B. These monitoring outputs are not specified as potential-free relay contacts. Follow the complete application circuit for signal return paths, external indicators or relay loads and the inhibit switch. The diagrams show both a signal supply taken from the DC rail and a separate external signal supply; do not substitute an AC connection at these signal terminals. Protection Overvoltage 31–37.5 V: output-voltage shutdown. Overload in buffer mode 105–125% of rated output power as specified; output-voltage shutdown, re-power to recover. This is a protection threshold, not an additional continuous-output rating. Short circuit Output-voltage shutdown; re-power to recover. Reverse polarity Internal MOSFET protection; automatic recovery after the fault is removed. Signal TVS rating 35 V maximum, as listed in the protection table. Use the charging, buffer and signal-terminal limits for their respective circuits. Protection does not replace correct polarity, wiring or load sizing. Connection and Parallel Applications Main DC wiring Connect the regulated DC supply, load and buffer module to the same DC rails with the polarities shown in the general wiring diagram. The module’s main terminals are +V and −V; there are no AC L/N input terminals on this module. Parallel buffer units The catalogue allows parallel buffer modules to increase output capacity or extend buffering time and provides a two-unit example. Follow the illustrated main-rail and signal wiring for each unit. Parallel selection limits The assigned catalogue pages do not state a numerical maximum unit count or a guaranteed combined buffer-time formula. Keep each unit within its own ratings and size the upstream supply for charging demand as well as the load. External application components The diagrams show a power supply, load, Ready/Buffering relay or signal loads, an inhibit switch and an optional external signal-voltage source. Complete order codes and included quantities for these external items are not specified. The illustrated application parts are not a promise that relays, indicators, switches or another power supply are supplied with the DBUF20-24. Cooling and Environment Cooling / working temperature Free-air convection; −25 to +75°C. The vertical-installation load curve shows 100% through this range, subject to the other catalogue conditions. Working humidity 5–95% RH, non-condensing. Storage temperature −25 to +80°C. Temperature coefficient ±0.03%/°C over 0–75°C. Operating altitude Up to 5,000 m; overvoltage category II. Above 2,000 m, reduce the permissible ambient temperature by 3.5°C per 1,000 m for this fanless design. Shock test IEC60068-2-27; 30 G (300 m/s²), 18 ms, one time per direction and two times in total as listed. Vibration Component: 10–500 Hz, 2 G, 10 minutes per cycle, 60 minutes each along X, Y and Z. Mounting clip: compliance with IEC60068-2-6. Apply the installation orientation, altitude and DC operating limits together; the ambient-temperature endpoint does not remove the finite-energy buffering limit. Dimensions, Terminals and Mounting Dimensions, W × H × D 63 × 125.2 × 114.9 mm; drawing tolerance ±1 mm; case 979E. TB1 main terminals Pins 1 and 2: DC +V. Pins 3 and 4: DC −V.

MEAN WELL DBUF40 series: 24V 40A DIN Rail Capacitor Buffer Module - DBUF40-24
MEAN WELL DBUF40-24 is a DIN rail capacitor buffer module for regulated 24 V DC power supplies. It provides up to 40 A in buffer mode, typically for 250 ms at 22 V/40 A, and bridges short supply interruptions using stored capacitor energy. Select a fixed 22 V or dynamic Vin minus 1 V buffering threshold; it is not a standalone AC/DC power supply. Product Datasheet Download MEAN WELL DBUF40 Datasheet (PDF) The DBUF40 section is on PDF pages 8, 9, 10, 11, 12, 13, 14. Refer to the complete mechanical drawings and notes when planning installation. Model Code and Operating Principle Complete model DBUF40-24 DBUF DIN rail buffer module. 40 40 A maximum buffer-output-current class. 24 24 V DC nominal system operating voltage. Stored energy Electrolytic capacitors rather than lead-acid batteries. Applications Industrial control, semiconductor fabrication equipment, factory automation and electromechanical equipment. The module supplements a regulated DC supply. The block diagram includes reverse-polarity protection, input filtering, a boost converter with inrush limiting, capacitor storage, a buck converter, condition monitoring and optocoupled control/status interfaces. Capacitor buffering avoids periodic lead-acid battery replacement; it does not provide unlimited backup duration. Charging and Standby Nominal system voltage 24 V DC. Charging voltage 23–30 V DC. Charging current, maximum 900 mA. Standby current consumption, maximum 100 mA. Charging time 25 seconds typical; 35 seconds maximum. Allow the capacitor bank to charge before relying on the stated buffering times. The Ready indication distinguishes the charged state from charging or discharged operation. Account for the charging current when selecting the external DC supply. Buffer Output and Hold-up Time Buffer operating voltage 22 V DC in fixed mode, or Vin minus 1 V DC in dynamic mode. Buffer voltage range 22–29 V DC. Output current, maximum 40 A. At 22 V / 40 A 250 ms typical; 160 ms minimum. At 22 V / 20 A 500 ms typical; 320 ms minimum. At 22 V / 0.1 A 62 seconds typical; 42 seconds minimum. Ripple and noise, maximum 350 mVp-p. The typical 22 V buffering curve also marks approximately 1.0 second at 10 A, 0.5 second at 20 A and 0.25 second at 40 A. These are load-dependent typical values; use the separately listed minimum times where a minimum is required. The maximum-current rating does not mean continuous backup without recharging. Ripple and noise are measured with a 20 MHz bandwidth using a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors in parallel. Threshold Selection and Status Indication Fixed mode: factory setting Fix 22 V DC. Buffering starts when the terminal voltage falls below 22 V DC. Dynamic mode Vin minus 1 V DC. The specification starts buffering when the terminal voltage decreases by more than 1 V DC. LED steadily on Ready: capacitors fully charged. LED off Capacitors discharged. LED flashes at 1 Hz Charging. LED flashes at 10 Hz Buffering / capacitor discharge. The operating diagram separates charging, standby and buffer modes. Ready is high in the charged standby period and low during charging and buffering; Buffering is high during the buffer period and low in the other modes. The PSU hold-up interval and the module buffer interval are distinct. Control and Signal Electrical Limits Inhibit input I: module on +Vs − V(I) < 6 V DC. Inhibit input I: module off +Vs − V(I) > 10 V DC. Inhibit input rating, maximum 35 V DC / 4 mA. Ready R: charged V(R) > +Vs − 2 V DC. Ready R: unready V(R) < 1 V DC. Ready signal rating, maximum 35 V DC / 10 mA. Buffering B: buffering active V(B) > +Vs − 2 V DC. Buffering B: other modes V(B) < 1 V DC. Buffering signal rating, maximum 35 V DC / 10 mA. Signal supply +Vs 10–35 V DC / 10 mA; connected to module +V or an external voltage source. Signal protection 35 V maximum TVS rating is listed. Use the specified voltage differences when wiring Inhibit; do not treat its on/off limits as an ordinary voltage-to-ground logic input. The catalogue does not assign a logic state to the interval between the two Inhibit thresholds. The schematics show optocoupled control/status circuitry. External relays, lamps or signal interfaces shown in the application diagrams must remain within the signal ratings; they are not built-in dry relay contacts. Follow the full signal schematic and the internal-supply or external-supply wiring diagram. Protection and Recovery Overvoltage 31–37.5 V: output voltage shuts down. Overload in buffer mode 105–125% of rated output power; output voltage shuts down. Re-power on to recover. Short circuit Output voltage shuts down. Re-power on to recover. Reverse polarity Internal MOSFET protection prevents damage; automatic recovery after the fault condition is removed. The overvoltage entry specifies shutdown but does not separately state its recovery method. Use the stated re-power recovery for overload and short circuit; do not substitute a continuous current-limit or hiccup characteristic. System Wiring and Parallel Modules General arrangement Connect the regulated DC supply, load and buffer module to the common DC rails as shown in the application diagram. Signal supply arrangements The catalogue shows signal power from the module +V terminal and a separate arrangement using an external voltage source. Parallel buffer modules Supported to increase output ampacity or hold-up time; follow the complete parallel-module diagram. The parallel example connects both modules to the common DC rails and shows their control/status wiring. The reviewed pages do not specify a maximum module count, a current-sharing multiplier or a guaranteed linear extension of hold-up time; do not infer those limits from the example. Each module and all external supplies, wiring and signal interfaces must remain within their own ratings. Environment and Derating Cooling Free-air convection. Working ambient temperature −25 to +75°C. Temperature curve 100% load throughout −25 to +75°C in the illustrated vertical mounting position. Working humidity 5–95% RH, non-condensing. Storage temperature −25 to +80°C. Temperature coefficient ±0.03%/°C from 0 to 75°C. Operating altitude / category 5000 m maximum; overvoltage category II. Altitude temperature derating For this fanless model, reduce the permissible ambient temperature by 3.5°C per 1000 m above 2000 m (6500 ft). Shock IEC60068-2-27: 30 G (printed as 300 m/s²), 18 ms, once per direction and twice in total. Component vibration 10–500 Hz, 2 G, 10 minutes per cycle; 60 minutes along each X, Y and Z axis. Mounting clip vibration Compliance with IEC60068-2-6 is listed. The flat temperature curve applies to the documented vertical mounting and stated conditions. Apply altitude derating as well; the temperature range is not a substitute for ventilation and correct installation.
