Apply the input, thermal and programmed-output limits below. Product Datasheet Download MEAN WELL NSP-3200 Datasheet (PDF) The NSP-3200 section is on PDF pages 9, 10, 11, 12, 13, 14, 15, 16. Refer to the complete mechanical drawings and notes when planning installation. Model, Output and Control Range Complete model NSP-3200-48 Nominal DC output 48 V Rated current / current range 67 A / 0 to 67 A Rated output power 3216 W Maximum ripple and noise 480 mVp-p Built-in voltage adjustment 47.5 to 58.8 V Voltage tolerance / line / load regulation ±1.0% / ±0.5% / ±0.5% Typical efficiency 94.5%, measured at 75% load External voltage programming 50 to 125% of nominal voltage; 24.0 to 60.00 V Communication Built-in CANBus; CAN 2.0B The complete model comprises the NSP family, 3200 power class and 48 V output code. The actual rating is 3216 W; the family number is not an additional continuous power rating. Unless otherwise stated, measurements use 230 VAC, rated load and 25°C ambient; efficiency is specifically measured at 75% load. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors in parallel. Voltage tolerance includes setup, line and load regulation. Input, Timing and Protection Continuous input 90 to 264 VAC / 127 to 400 VDC; 47 to 63 Hz Typical power factor 0.97 at 230 VAC, full load Typical AC input current 17 A at 230 VAC Typical cold-start inrush 55 A at 230 VAC Leakage current <2 mA at 230 VAC Setup / rise time 1500 / 60 ms at 230 VAC, full load Typical hold-up time 16 ms at 70% load; 8 ms at full load, 230 VAC Overload threshold 105 to 115% of rated output power Overvoltage threshold 63 to 75 V Active PFC and active inrush-current limiting are shown in the block diagram. PFC and PWM switching frequencies are 110 kHz and 90 kHz respectively. Short-circuit/overload protection uses constant-current limiting. The output shuts down 5 seconds after the output voltage has fallen low; re-power to recover. This is a protection behavior, not a separate uninterrupted constant-current output rating. Overvoltage protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after temperature falls. Cooling, Environment and Derating Cooling Built-in DC fans with intelligent speed control based on internal PSU temperature Working temperature -20 to +70°C, with derating Typical fan noise at 25°C 38 dB at 10% load; 38 dB at 70% load; ISO 7779 test setup Humidity / storage Operation: 20 to 90% RH, non-condensing; storage: -40 to +85°C, 10 to 95% RH, non-condensing Temperature coefficient ±0.03%/°C from 0 to 50°C The 60 Hz input-derating table permits 3216 W / 67 A at 180 to 264 VAC and 1608 W / 33.5 A at 90 VAC. Printed curve annotations show approximately 55% load at 100 VAC and 64% at 115 VAC; follow the complete curve between these points. For the illustrated horizontal mounting, the temperature curve permits full load from -20 to 50°C, then 75% at 60°C and 50% at 70°C. Apply the input and temperature limits together; the upper temperature is not a full-load rating. The efficiency-versus-load graph applies to the 48 V model at 230 VAC. It does not establish an efficiency curve for all models or input conditions. Above 2000 m altitude, reduce allowable ambient temperature by 5°C per additional 1000 m for this fan-cooled model. The note does not specify an unlimited or exact maximum altitude. Keep the illustrated airflow path clear. Vibration: 10 to 500 Hz, 2 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Voltage Programming and Sensing Apply the external DC voltage-programming signal to CN1 pin 12 (PV), referenced to pin 14 (-Vo Signal). This analog control range is separate from adjustment by the built-in potentiometer. Follow the complete PV curve: below approximately 0.4 V control the diagram shows nominal output; 0.4 to 1 V selects the 50% minimum. Marked points then indicate about 70% at 2 V, 90% at 3 V, 110% at 4 V and 125% at 4.7 to 5 V. The transition at the low end means the whole control range must not be treated as one linear conversion. The permitted output current also changes with programmed voltage: 80% of rated current from 50 to 90% nominal voltage, rising to 100% at 95%, remaining 100% through nominal voltage, then falling to 80% at 125%. Follow the diagram and all input/thermal limits. With PV adjustment, ripple/noise may under some operating conditions slightly exceed the normal specified limit. Remote sense compensates up to 0.5 V of load-wiring drop. Connect CN1 pin 15 (+RS) to the positive load terminal and pin 16 (-RS) to the negative load terminal; twist the sense pair to reduce noise pickup. When remote sense is not used, connect pin 15 to pin 13 (+Vo Signal) and pin 16 to pin 14 (-Vo Signal) for local sensing. Do not additionally bridge these sense leads locally while using the remote-load sensing connection. Signal pins 13 and 14 cannot supply the load. Remote Control, Auxiliary Power and Alarms For dry-contact remote ON/OFF, connect a switch between CN1 pin 3 (+5V-aux) and pin 4 (R.C): short is ON, open is OFF. For electrical control, pin 4 is an isolated signal referenced to pin 2 (GND-aux); 4.5 to 5.5 V is ON and -0.5 to +0.5 V is OFF, maximum 5.5 V. Pin 3 is only for remote-control use, not a rated general-purpose 5 V supply. CN1 pin 1 provides nominal 12 V auxiliary power at up to 0.8 A relative to pin 2. The specification lists ±10% tolerance; the detailed pin table gives 10.6 to 13.2 V. It incorporates ORing diodes, is isolated from the main output and remains independent of remote ON/OFF. DC-OK (CN1 pin 5) and T-ALARM (pin 6) are isolated TTL outputs referenced to GND-aux, with a 10 mA maximum signal-current rating. DC-OK is high, 3.5 to 5.5 V, when output is at or below 77% ±5%, and low, -0.5 to +0.5 V, when output is at or above 80% ±5%. High therefore indicates the DC-output failure condition, not OK. T-ALARM is high, 3.5 to 5.5 V, for an internal temperature alarm or fan failure, and low, -0.5 to +0.5 V, when internal temperature and fan operation are normal. The LED is green during normal operation and steady red for an abnormal condition such as OTP, OLP or fan failure. Flashing red at 60°C internal temperature is an early warning: the unit still operates normally without entering OTP, and an alarm is also sent over CANBus. This is internal temperature, not a 60°C ambient switch point. CANBus and Connector Pin Assignments The built-in CAN 2.0B interface supports information reading, status monitoring and output trimming. The datasheet lists a maximum bus speed of 250 kHz; use the manufacturer user manual for the complete protocol and setup. CN1 uses HRS DF11-16DP-2DS or equivalent, with HRS DF11-16DS mating housing or equivalent. Pins are 1 +12V-aux, 2 GND-aux, 3 +5V-aux (remote-control use only), 4 R.C, 5 DC-OK, 6 T-ALARM, 7/8/9 A0/A1/A2 CANBus address lines, 10/11 NC, 12 PV, 13 +Vo Signal, 14 -Vo Signal, 15 +RS and 16 -RS. Address and PV signals are non-isolated and referenced to -Vo Signal. CN2 uses HRS DF11-8DP-2DS or equivalent, with HRS DF11-8DS mating housing or equivalent. Pins 1 to 4 are NC; pins 5 and 6 are -Vo Signal and cannot connect directly to the load; pins 7 and 8 are CANH and CANL. CAN data signals are isolated and referenced to GND-aux; do not interchange the isolated return with -Vo Signal. The printed crimp-contact reference for these connectors is HRS DF11-**SC or equivalent. The asterisks are an incomplete contact designation, so the exact contact must be selected for the wire and housing before ordering. No unlisted contact suffix is implied. Dimensions, Weight and Mounting Housing dimensions (L × W × H) 325.8 × 107 × 41 mm; 1U low profile Catalog single-unit packing reference 2240 g (2.24 kg per unit) Packing reference 4 pcs / 10 kg / 1.09 CUFT Case / drawing tolerance Case No. 294A; dimensions in mm, ±0.5 mm The manufacturer describes the series as reaching up to 37 W/in³ power density; this is a family-level claim, not a separately established value for every operating point. The single-unit packing reference is not a measured net or parcel weight. The side view marks 2-M4 L=5 on each side and the bottom 3-M3 L=4. M3 mounting screws have a maximum penetration depth of 4 mm and recommended torque 6 to 8 kgf·cm; M4 has maximum penetration 5 mm and torque 7 to 10 kgf·cm. Allow for the terminal and bracket envelope as shown in the full drawing: -Vo and +Vo output bars extend 28 mm and 38 mm respectively, while the AC terminal projection is 12 mm maximum. The output-hole diameter is 6.5 mm; bracket-related transverse dimensions are 127 and 137 mm. These are separate from the 107 mm housing width. AC input terminals are 1 FG (protective earth), 2 AC/N and 3 AC/L. Their screw thread is M3.5 and maximum torque is 8 kgf·cm. Do not apply case-mounting torque indiscriminately to electrical terminals. Follow the drawing for hole centres and keep airflow from the terminal end toward the rear fans unobstructed. Supplied Control Wire and Optional Brackets One CN1 control-interface mating wire assembly per unit is listed as a standard accessory. The drawing identifies HRS DF11-16DS or equivalent and UL1007 26AWG wire. Its inclusion is distinct from unlisted spare housings or contacts; no separate complete MEAN WELL assembly-order code is supplied in this list. Mounting bracket PGG2MHS013A is a by-request accessory ordered separately, four brackets per unit. The installation diagram shows the four bracket positions and labels the combination screw M4 × 4. This screw-size label does not establish an additional order code or that screws are supplied with the bracket. Retain the mounting-depth and torque limits above. Safety, EMC and Reliability The datasheet lists approval to UL62368-1, CSA C22.2 No. 62368-1, TUV BS EN/EN62368-1, BIS IS 13252 (Part 1):2010 / IEC 60950-1:2005 and EAC TP TC 004. SEMI F47 is a design reference at 200 VAC, not an unconditional certification statement. Dielectric withstand: input-to-output 3 kVAC, input-to-FG 2 kVAC and output-to-FG 1.5 kVAC. Insulation resistance for the three paths is 100 MΩ at 500 VDC, 25°C and 70% RH. Emissions: BS EN/EN55032 (CISPR32), conducted Class B and radiated Class A; harmonic current BS EN/EN61000-3-2 Class A; voltage flicker BS EN/EN61000-3-3. Immunity: BS EN/EN55024 and BS EN/EN61000-6-2. IEC/EN61000-4 tests list ESD at 8 kV air / 4 kV contact; radiated RF, EFT/burst and conducted RF Level 3; surge 2 kV line-line / 4 kV line-earth; magnetic field Level 4. Voltage dips/interruption are >95% for 0.5 periods, 30% for 25 periods and >95% for 250 periods. This supply is a component for installation in final equipment. EMC tests mount it on a 600 × 900 mm metal plate, 1 mm thick; the finished equipment must be reconfirmed against its EMC requirements. MTBF is 637.4K hours minimum by Telcordia SR-332 (Bellcore), or 63.7K hours minimum by MIL-HDBK-217F at 25°C. MTBF is a reliability calculation, not a service-life guarantee.

MEAN WELL NSP-3200-24 is a single-output enclosed industrial AC/DC power supply rated at 24 V DC, 133 A and 3192 W. It accepts 90 to 264 VAC or 127 to 400 VDC and combines active PFC, intelligent fan cooling, built-in CANBus, voltage programming and remote sensing in a 41 mm low-profile housing. Apply the input, thermal and programmed-output limits below. Product Datasheet Download MEAN WELL NSP-3200 Datasheet (PDF) The NSP-3200 section is on PDF pages 9, 10, 11, 12, 13, 14, 15, 16. Refer to the complete mechanical drawings and notes when planning installation. Model, Output and Control Range Complete model NSP-3200-24 Nominal DC output 24 V Rated current / current range 133 A / 0 to 133 A Rated output power 3192 W Maximum ripple and noise 300 mVp-p Built-in voltage adjustment 23.5 to 30 V Voltage tolerance / line / load regulation ±1.0% / ±0.5% / ±0.5% Typical efficiency 93.5%, measured at 75% load External voltage programming 50 to 125% of nominal voltage; 12.0 to 30.00 V Communication Built-in CANBus; CAN 2.0B The complete model comprises the NSP family, 3200 power class and 24 V output code. The actual rating is 3192 W; the family number is not an additional continuous power rating. Unless otherwise stated, measurements use 230 VAC, rated load and 25°C ambient; efficiency is specifically measured at 75% load. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with 0.1 µF and 47 µF capacitors in parallel. Voltage tolerance includes setup, line and load regulation. Input, Timing and Protection Continuous input 90 to 264 VAC / 127 to 400 VDC; 47 to 63 Hz Typical power factor 0.97 at 230 VAC, full load Typical AC input current 17 A at 230 VAC Typical cold-start inrush 55 A at 230 VAC Leakage current <2 mA at 230 VAC Setup / rise time 1500 / 60 ms at 230 VAC, full load Typical hold-up time 16 ms at 70% load; 8 ms at full load, 230 VAC Overload threshold 105 to 115% of rated output power Overvoltage threshold 31.5 to 37.5 V Active PFC and active inrush-current limiting are shown in the block diagram. PFC and PWM switching frequencies are 110 kHz and 90 kHz respectively. Short-circuit/overload protection uses constant-current limiting. The output shuts down 5 seconds after the output voltage has fallen low; re-power to recover. This is a protection behavior, not a separate uninterrupted constant-current output rating. Overvoltage protection shuts down the output and requires re-powering. Overtemperature protection shuts down the output and recovers automatically after temperature falls. Cooling, Environment and Derating Cooling Built-in DC fans with intelligent speed control based on internal PSU temperature Working temperature -20 to +70°C, with derating Typical fan noise at 25°C 38 dB at 10% load; 44 dB at 70% load; ISO 7779 test setup Humidity / storage Operation: 20 to 90% RH, non-condensing; storage: -40 to +85°C, 10 to 95% RH, non-condensing Temperature coefficient ±0.03%/°C from 0 to 50°C The 60 Hz input-derating table permits 3192 W / 133 A at 180 to 264 VAC and 1596 W / 66.5 A at 90 VAC. Printed curve annotations show approximately 55% load at 100 VAC and 64% at 115 VAC; follow the complete curve between these points. For the illustrated horizontal mounting, the temperature curve permits full load from -20 to 50°C, then 75% at 60°C and 50% at 70°C. Apply the input and temperature limits together; the upper temperature is not a full-load rating. The efficiency-versus-load graph applies to the 48 V model at 230 VAC. It does not establish an efficiency curve for all models or input conditions. Above 2000 m altitude, reduce allowable ambient temperature by 5°C per additional 1000 m for this fan-cooled model. The note does not specify an unlimited or exact maximum altitude. Keep the illustrated airflow path clear. Vibration: 10 to 500 Hz, 2 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Voltage Programming and Sensing Apply the external DC voltage-programming signal to CN1 pin 12 (PV), referenced to pin 14 (-Vo Signal). This analog control range is separate from adjustment by the built-in potentiometer. Follow the complete PV curve: below approximately 0.4 V control the diagram shows nominal output; 0.4 to 1 V selects the 50% minimum. Marked points then indicate about 70% at 2 V, 90% at 3 V, 110% at 4 V and 125% at 4.7 to 5 V. The transition at the low end means the whole control range must not be treated as one linear conversion. The permitted output current also changes with programmed voltage: 80% of rated current from 50 to 90% nominal voltage, rising to 100% at 95%, remaining 100% through nominal voltage, then falling to 80% at 125%. Follow the diagram and all input/thermal limits. With PV adjustment, ripple/noise may under some operating conditions slightly exceed the normal specified limit. Remote sense compensates up to 0.5 V of load-wiring drop. Connect CN1 pin 15 (+RS) to the positive load terminal and pin 16 (-RS) to the negative load terminal; twist the sense pair to reduce noise pickup. When remote sense is not used, connect pin 15 to pin 13 (+Vo Signal) and pin 16 to pin 14 (-Vo Signal) for local sensing. Do not additionally bridge these sense leads locally while using the remote-load sensing connection. Signal pins 13 and 14 cannot supply the load. Remote Control, Auxiliary Power and Alarms For dry-contact remote ON/OFF, connect a switch between CN1 pin 3 (+5V-aux) and pin 4 (R.C): short is ON, open is OFF. For electrical control, pin 4 is an isolated signal referenced to pin 2 (GND-aux); 4.5 to 5.5 V is ON and -0.5 to +0.5 V is OFF, maximum 5.5 V. Pin 3 is only for remote-control use, not a rated general-purpose 5 V supply. CN1 pin 1 provides nominal 12 V auxiliary power at up to 0.8 A relative to pin 2. The specification lists ±10% tolerance; the detailed pin table gives 10.6 to 13.2 V. It incorporates ORing diodes, is isolated from the main output and remains independent of remote ON/OFF. DC-OK (CN1 pin 5) and T-ALARM (pin 6) are isolated TTL outputs referenced to GND-aux, with a 10 mA maximum signal-current rating. DC-OK is high, 3.5 to 5.5 V, when output is at or below 77% ±5%, and low, -0.5 to +0.5 V, when output is at or above 80% ±5%. High therefore indicates the DC-output failure condition, not OK. T-ALARM is high, 3.5 to 5.5 V, for an internal temperature alarm or fan failure, and low, -0.5 to +0.5 V, when internal temperature and fan operation are normal. The LED is green during normal operation and steady red for an abnormal condition such as OTP, OLP or fan failure. Flashing red at 60°C internal temperature is an early warning: the unit still operates normally without entering OTP, and an alarm is also sent over CANBus. This is internal temperature, not a 60°C ambient switch point. CANBus and Connector Pin Assignments The built-in CAN 2.0B interface supports information reading, status monitoring and output trimming. The datasheet lists a maximum bus speed of 250 kHz; use the manufacturer user manual for the complete protocol and setup. CN1 uses HRS DF11-16DP-2DS or equivalent, with HRS DF11-16DS mating housing or equivalent. Pins are 1 +12V-aux, 2 GND-aux, 3 +5V-aux (remote-control use only), 4 R.C, 5 DC-OK, 6 T-ALARM, 7/8/9 A0/A1/A2 CANBus address lines, 10/11 NC, 12 PV, 13 +Vo Signal, 14 -Vo Signal, 15 +RS and 16 -RS. Address and PV signals are non-isolated and referenced to -Vo Signal. CN2 uses HRS DF11-8DP-2DS or equivalent, with HRS DF11-8DS mating housing or equivalent. Pins 1 to 4 are NC; pins 5 and 6 are -Vo Signal and cannot connect directly to the load; pins 7 and 8 are CANH and CANL. CAN data signals are isolated and referenced to GND-aux; do not interchange the isolated return with -Vo Signal. The printed crimp-contact reference for these connectors is HRS DF11-**SC or equivalent. The asterisks are an incomplete contact designation, so the exact contact must be selected for the wire and housing before ordering. No unlisted contact suffix is implied.

The output-hole diameter is 6.5 mm; bracket-related transverse dimensions are 127 and 137 mm. These are separate from the 107 mm housing width. AC input terminals are 1 FG (protective earth), 2 AC/N and 3 AC/L. Their screw thread is M3.5 and maximum torque is 8 kgf·cm. Do not apply case-mounting torque indiscriminately to electrical terminals. Follow the drawing for hole centres and keep airflow from the terminal end toward the rear fans unobstructed.

It accepts 90-264 VAC or 250-400 VDC with active PFC and intelligent fan cooling in a 41 mm 1U body. CANBus, output-voltage programming, remote ON/OFF, remote sense and isolated alarm signals support system integration; observe the model-specific programming and derating limits. Product Datasheet Download MEAN WELL NSP-1600 Datasheet (PDF) The NSP-1600 section is on PDF pages 1, 2, 3, 4, 5, 6, 7, 8. Refer to the complete mechanical drawings and notes when planning installation. Model Code and Configuration NSP-1600 NSP single-output industrial enclosed AC/DC power-supply family; 1600 is the family designation, not the guaranteed wattage of every output model. -48 48 V nominal DC output; the complete ordering model is NSP-1600-48. Standard and requested configuration The extended 15-125% PV range and optional mounting brackets require separate confirmation/order. No additional suffix or requested feature is inferred from this unsuffixed SKU. Output Ratings Nominal output 48 VDC; 33.5 A rated current; 1608 W rated power. Operating current range 0-33.5 A, subject to input-voltage, temperature and programmed-output limits. Built-in voltage adjustment 47.5-58.8 V using the built-in potentiometer; distinct from the external PV range. Ripple and noise 300 mVp-p maximum under the specified measurement conditions. Accuracy / regulation Voltage tolerance ±1.0%; line regulation ±0.5%; load regulation ±0.5%. Timing Setup 1500 ms and rise 60 ms at 230 VAC/full load. Typical hold-up: 16 ms at 230 VAC/70% load; 10 ms at 230 VAC/full load. Unless stated otherwise, specifications are measured at 230 VAC, rated load and 25°C ambient. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with 0.1 µF and 47 µF parallel capacitors. Voltage tolerance includes setup, line and load regulation. External PV adjustment may cause ripple/noise to exceed the tabulated rating under some operating conditions. Input and Efficiency Input range 90-264 VAC, 47-63 Hz, or 250-400 VDC; low-line load limits apply. Typical efficiency / power factor 92.5% efficiency; power factor 0.97 at 230 VAC/full load. Typical AC input current 15 A at 115 VAC; 8.5 A at 230 VAC. Starting and leakage current Typical cold-start inrush 35 A at 230 VAC; leakage <2 mA at 230 VAC. The block diagram includes active inrush-current limiting and active PFC. Its PFC and PWM switching-frequency labels are 90 kHz and 70 kHz, respectively. The efficiency-versus-load curve is specifically for the 48 V model at 115/230 VAC; it is not a measured curve for every output variant. Input and Temperature Derating 180-264 VAC 1608 W / 33.5 A; static-characteristic values are at 60 Hz. 115 VAC 1286 W / 26.8 A (published table values). 100 VAC 1126 W / 23.45 A (published table values). 90 VAC 965 W / 20.1 A (published table values). The 60 Hz input curve shows 60% load at 90 VAC, 70% at 100 VAC, 80% at 115 VAC and 100% from 180 to 264 VAC. The printed low-line wattages and currents are retained independently; rounded table values should not be treated as extra output allowance. In the horizontal mounting orientation, the ambient curve permits 100% load from -20 to +50°C, derating to 75% at +60°C and 50% at +70°C. Apply both input and temperature limits; do not claim full power throughout the entire input/temperature range. For this fan-cooled unit above 2000 m, reduce the allowable ambient temperature by 5°C per additional 1000 m. These pages do not specify a maximum operating altitude. Protection Short circuit / overload Overload threshold 105-115% of rated output power. Constant-current limiting; after output voltage falls, the unit shuts down output after 5 seconds. Re-power on to recover. Overvoltage 63-75 V; output shuts down and re-powering is required. Overtemperature Output shuts down; automatic recovery after temperature falls. Environment and Cooling Operating environment -20 to +70°C with derating; 20-90% RH, non-condensing. Storage environment -40 to +85°C; 10-95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C from 0 to +50°C; vibration 10-500 Hz, 2 G, 10 min/cycle, 60 min each along X, Y and Z. Typical fan noise At 25°C ambient: 38 dB at 10% load; 38 dB at 70% load. Test setup follows ISO-7779. A built-in DC fan provides forced-air cooling with speed controlled by internal PSU temperature. The diagram shows airflow from the terminal end toward the rear fan end. No fan-stop threshold or numerical external ventilation clearance is specified in these pages. External Output-Voltage Programming The standard PV range for NSP-1600-48 is 40-125% of nominal output voltage. A 15-125% range is available only by request; it is not assumed fitted to this model. Apply the external DC control voltage between CN1 pin 12 (PV) and pin 14 (-Vo(Signal)); this reference is non-isolated from the main output. Use the required remote- or local-sense connections below. The page 4 curve shows these external-voltage anchors: 1 V → 40%, 2 V → 63%, 3 V → 86%, 4.7 V → 125%. The diagram labels the PV relationship non-linear and includes a 0.4 V transition; use the plotted anchors rather than extrapolating one linear conversion. Adjust the permissible current with programmed voltage: the graph permits 100% rated current up to 100% nominal voltage, falling to 80% rated current at 125% voltage. Observe all other power, input and temperature limits. Constant-current limiting is documented as protection. These NSP-1600 pages do not specify a separate external PC input, an active parallel current-share connection or a permissible parallel-unit count; do not infer these from another power-supply family. Remote Control and Sense Connections For ON, short CN1 pin 3 (+5V-aux) to pin 4 (R.C); for OFF, open that connection. Pin 4 is rated 4.5-5.5 V for ON and -0.5 to +0.5 V for OFF, maximum input 5.5 V. Pin 3 is for this control function only. The isolated control reference is GND-aux, not the main negative output. External switch, optocoupler and relay examples are provided on page 4; those user control devices and their power sources are not listed as supplied accessories. Multiple-unit ON/OFF control is not evidence of output current sharing. Remote sense compensates load-wire drop up to 0.5 VDC: connect pin 15 (+RS) to load positive and pin 16 (-RS) to load negative. Twist the sense wires together to reduce noise pickup. When remote sense is unused, local-sense links are required: pin 15 (+RS) to pin 13 (+Vo(Signal)), and pin 16 (-RS) to pin 14 (-Vo(Signal)). Use the main copper bars for load current; the signal and sense pins cannot power the load. A CN1 mating-wire assembly is listed as a standard accessory. Before operation, verify the ON/local-sense connections against pages 4-7 rather than assuming arbitrary jumper pairs from a different model. CN1 Control Pin Assignment 1 / +12V-aux 10.6-13.2 VDC auxiliary output, maximum 0.8 A, referenced to GND-aux pin 2. Built-in ORing diodes; unaffected by remote ON/OFF. 2 / GND-aux Auxiliary and isolated control/alarm return; isolated from the main +Vo and -Vo output terminals. 3 / +5V-aux For remote ON/OFF use only; not a general-purpose auxiliary load supply. 4 / R.C Remote ON/OFF input. Short to +5V-aux pin 3 for ON (4.5-5.5 V); open for OFF (-0.5 to +0.5 V). Maximum input 5.5 V; isolated reference is GND-aux. 5 / DC-OK Isolated output-status signal referenced to GND-aux pin 2; see the alarm levels and thresholds below. 6 / T-ALARM Isolated temperature/fan-failure alarm output referenced to GND-aux pin 2; see the alarm levels below. 7, 8, 9 / A0, A1, A2 CANBus address lines; non-isolated, referenced to -Vo(Signal). Address settings require the manufacturer User Manual. 10, 11 / NC Reserved for future use; no user function is specified. 12 / PV External output-voltage programming input; non-isolated, referenced to -Vo(Signal) pin 14. 13 / +Vo(Signal) Positive local-sense signal; cannot be connected directly to the load. 14 / -Vo(Signal) Negative local-sense and function-reference signal; cannot be connected directly to the load. 15 / +RS Positive remote-sense input; connect to load positive, or to pin 13 for local sense. 16 / -RS Negative remote-sense input; connect to load negative, or to pin 14 for local sense. CN1 has 16 positions. The onboard header is HRS DF11-16DP-2DS or equivalent; the mating housing is HRS DF11-16DS or equivalent. Contacts are printed as HRS DF11-**SC or equivalent; ** is an unspecified variant, not a complete orderable contact code. Use the connector orientation in the mechanical drawing. A0/A1/A2 and PV are non-isolated references to -Vo(Signal); remote-control and alarm signals are isolated references to GND-aux. Alarms, LED and Auxiliary Output DC-OK pin 5 High 3.5-5.5 V when Vout ≤77% ±5%; low -0.5 to +0.5 V when Vout ≥80% ±5%. Reference: GND-aux pin 2. T-ALARM pin 6 High 3.5-5.5 V for overtemperature or fan failure (output OFF); low -0.5 to +0.5 V for normal internal temperature and fan operation (output ON). Reference: pin 2. LED indication Green: normal. Constant red: OTP, OLP or fan failure. Flashing red: internal temperature reaches 60°C; the unit still operates normally without entering OTP and sends a CANBus alarm. Alarm outputs are isolated TTL signals with a 10 mA maximum signal-current figure. The function text calls this a sink limit, whereas the pin table calls it a sourcing limit; confirm the required sink/source interface before connecting a direction-dependent load. The flashing-red 60°C figure is an internal temperature warning, not the ambient full-load limit or a specified fan-start temperature. The auxiliary supply is 12 V nominal (10.6-13.2 VDC), maximum 0.8 A, between CN1 pins 1 and 2. It contains ORing diodes and is not controlled by remote ON/OFF; do not extend this ORing statement to the main output. CANBus and CN2 Interface 1, 2, 3, 4 / NC Reserved for future use in the standard model. 5, 6 / -Vo(Signal) Negative local-sense/function-reference signal; cannot be connected directly to the load. 7 / CANH, 8 / CANL CANBus data lines; isolated and referenced to GND-aux. The pin table labels these as the CANBus-model interface. The family lists a built-in CANBus interface for control, settings, information reading, status monitoring and output trimming. Page 5 states CAN 2.0B with a maximum bus-speed figure printed as 250 kHz. Confirm the communication timing, address settings and commands in the manufacturer User Manual; this catalog does not provide those details. CN2 has 8 positions: onboard HRS DF11-8DP-2DS or equivalent, mating HRS DF11-8DS or equivalent, contacts HRS DF11-**SC or equivalent. The exact contact variant and a supplied CN2 cable quantity are not specified. Do not interchange CN1 and CN2 housings or invent a CAN ordering suffix.

MEAN WELL NSP-1600-36 is a single-output enclosed industrial AC/DC power supply rated 36 V, 44.5 A and 1602 W. It accepts 90-264 VAC or 250-400 VDC with active PFC and intelligent fan cooling in a 41 mm 1U body. CANBus, output-voltage programming, remote ON/OFF, remote sense and isolated alarm signals support system integration; observe the model-specific programming and derating limits. Product Datasheet Download MEAN WELL NSP-1600 Datasheet (PDF) The NSP-1600 section is on PDF pages 1, 2, 3, 4, 5, 6, 7, 8. Refer to the complete mechanical drawings and notes when planning installation. Model Code and Configuration NSP-1600 NSP single-output industrial enclosed AC/DC power-supply family; 1600 is the family designation, not the guaranteed wattage of every output model. -36 36 V nominal DC output; the complete ordering model is NSP-1600-36. Standard and requested configuration The extended 15-125% PV range and optional mounting brackets require separate confirmation/order. No additional suffix or requested feature is inferred from this unsuffixed SKU. Output Ratings Nominal output 36 VDC; 44.5 A rated current; 1602 W rated power. Operating current range 0-44.5 A, subject to input-voltage, temperature and programmed-output limits. Built-in voltage adjustment 35.5-45 V using the built-in potentiometer; distinct from the external PV range. Ripple and noise 250 mVp-p maximum under the specified measurement conditions. Accuracy / regulation Voltage tolerance ±1.0%; line regulation ±0.5%; load regulation ±0.5%. Timing Setup 1500 ms and rise 60 ms at 230 VAC/full load. Typical hold-up: 16 ms at 230 VAC/70% load; 10 ms at 230 VAC/full load. Unless stated otherwise, specifications are measured at 230 VAC, rated load and 25°C ambient. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with 0.1 µF and 47 µF parallel capacitors. Voltage tolerance includes setup, line and load regulation. External PV adjustment may cause ripple/noise to exceed the tabulated rating under some operating conditions. Input and Efficiency Input range 90-264 VAC, 47-63 Hz, or 250-400 VDC; low-line load limits apply. Typical efficiency / power factor 91.5% efficiency; power factor 0.97 at 230 VAC/full load. Typical AC input current 15 A at 115 VAC; 8.5 A at 230 VAC. Starting and leakage current Typical cold-start inrush 35 A at 230 VAC; leakage <2 mA at 230 VAC. The block diagram includes active inrush-current limiting and active PFC. Its PFC and PWM switching-frequency labels are 90 kHz and 70 kHz, respectively. The efficiency-versus-load curve is specifically for the 48 V model at 115/230 VAC; it is not a measured curve for every output variant. Input and Temperature Derating 180-264 VAC 1602 W / 44.5 A; static-characteristic values are at 60 Hz. 115 VAC 1282 W / 35.6 A (published table values). 100 VAC 1121 W / 31.15 A (published table values). 90 VAC 961 W / 26.7 A (published table values). The 60 Hz input curve shows 60% load at 90 VAC, 70% at 100 VAC, 80% at 115 VAC and 100% from 180 to 264 VAC. The printed low-line wattages and currents are retained independently; rounded table values should not be treated as extra output allowance. In the horizontal mounting orientation, the ambient curve permits 100% load from -20 to +50°C, derating to 75% at +60°C and 50% at +70°C. Apply both input and temperature limits; do not claim full power throughout the entire input/temperature range. For this fan-cooled unit above 2000 m, reduce the allowable ambient temperature by 5°C per additional 1000 m. These pages do not specify a maximum operating altitude. Protection Short circuit / overload Overload threshold 105-115% of rated output power. Constant-current limiting; after output voltage falls, the unit shuts down output after 5 seconds. Re-power on to recover. Overvoltage 47.2-56.3 V; output shuts down and re-powering is required. Overtemperature Output shuts down; automatic recovery after temperature falls. Environment and Cooling Operating environment -20 to +70°C with derating; 20-90% RH, non-condensing. Storage environment -40 to +85°C; 10-95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C from 0 to +50°C; vibration 10-500 Hz, 2 G, 10 min/cycle, 60 min each along X, Y and Z. Typical fan noise At 25°C ambient: 38 dB at 10% load; 38 dB at 70% load. Test setup follows ISO-7779. A built-in DC fan provides forced-air cooling with speed controlled by internal PSU temperature. The diagram shows airflow from the terminal end toward the rear fan end. No fan-stop threshold or numerical external ventilation clearance is specified in these pages. External Output-Voltage Programming The standard PV range for NSP-1600-36 is 40-125% of nominal output voltage. A 15-125% range is available only by request; it is not assumed fitted to this model. Apply the external DC control voltage between CN1 pin 12 (PV) and pin 14 (-Vo(Signal)); this reference is non-isolated from the main output. Use the required remote- or local-sense connections below. The page 4 curve shows these external-voltage anchors: 1 V → 40%, 2 V → 63%, 3 V → 86%, 4.7 V → 125%. The diagram labels the PV relationship non-linear and includes a 0.4 V transition; use the plotted anchors rather than extrapolating one linear conversion. Adjust the permissible current with programmed voltage: the graph permits 100% rated current up to 100% nominal voltage, falling to 80% rated current at 125% voltage. Observe all other power, input and temperature limits. Constant-current limiting is documented as protection. These NSP-1600 pages do not specify a separate external PC input, an active parallel current-share connection or a permissible parallel-unit count; do not infer these from another power-supply family.

Pin 3 is for this control function only. The isolated control reference is GND-aux, not the main negative output. External switch, optocoupler and relay examples are provided on page 4; those user control devices and their power sources are not listed as supplied accessories. Multiple-unit ON/OFF control is not evidence of output current sharing. Remote sense compensates load-wire drop up to 0.5 VDC: connect pin 15 (+RS) to load positive and pin 16 (-RS) to load negative.

Operating current range 0-67 A, subject to input-voltage, temperature and programmed-output limits. Built-in voltage adjustment 23.5-30 V using the built-in potentiometer; distinct from the external PV range. Ripple and noise 200 mVp-p maximum under the specified measurement conditions. Accuracy / regulation Voltage tolerance ±1.0%; line regulation ±0.5%; load regulation ±0.5%. Timing Setup 1500 ms and rise 60 ms at 230 VAC/full load. Typical hold-up: 16 ms at 230 VAC/70% load; 10 ms at 230 VAC/full load. Unless stated otherwise, specifications are measured at 230 VAC, rated load and 25°C ambient. Ripple/noise uses 20 MHz bandwidth and a 12-inch twisted pair terminated with 0.1 µF and 47 µF parallel capacitors. Voltage tolerance includes setup, line and load regulation. External PV adjustment may cause ripple/noise to exceed the tabulated rating under some operating conditions. Input and Efficiency Input range 90-264 VAC, 47-63 Hz, or 250-400 VDC; low-line load limits apply. Typical efficiency / power factor 91% efficiency; power factor 0.97 at 230 VAC/full load. Typical AC input current 15 A at 115 VAC; 8.5 A at 230 VAC. Starting and leakage current Typical cold-start inrush 35 A at 230 VAC; leakage <2 mA at 230 VAC. The block diagram includes active inrush-current limiting and active PFC. Its PFC and PWM switching-frequency labels are 90 kHz and 70 kHz, respectively. The efficiency-versus-load curve is specifically for the 48 V model at 115/230 VAC; it is not a measured curve for every output variant. Input and Temperature Derating 180-264 VAC 1608 W / 67 A; static-characteristic values are at 60 Hz. 115 VAC 1286 W / 53.6 A (published table values). 100 VAC 1126 W / 46.9 A (published table values). 90 VAC 965 W / 40.2 A (published table values). The 60 Hz input curve shows 60% load at 90 VAC, 70% at 100 VAC, 80% at 115 VAC and 100% from 180 to 264 VAC. The printed low-line wattages and currents are retained independently; rounded table values should not be treated as extra output allowance. In the horizontal mounting orientation, the ambient curve permits 100% load from -20 to +50°C, derating to 75% at +60°C and 50% at +70°C. Apply both input and temperature limits; do not claim full power throughout the entire input/temperature range. For this fan-cooled unit above 2000 m, reduce the allowable ambient temperature by 5°C per additional 1000 m. These pages do not specify a maximum operating altitude. Protection Short circuit / overload Overload threshold 105-115% of rated output power. Constant-current limiting; after output voltage falls, the unit shuts down output after 5 seconds. Re-power on to recover. Overvoltage 31.5-37.5 V; output shuts down and re-powering is required. Overtemperature Output shuts down; automatic recovery after temperature falls. Environment and Cooling Operating environment -20 to +70°C with derating; 20-90% RH, non-condensing. Storage environment -40 to +85°C; 10-95% RH, non-condensing. Temperature coefficient / vibration ±0.03%/°C from 0 to +50°C; vibration 10-500 Hz, 2 G, 10 min/cycle, 60 min each along X, Y and Z. Typical fan noise At 25°C ambient: 38 dB at 10% load; 38 dB at 70% load. Test setup follows ISO-7779. A built-in DC fan provides forced-air cooling with speed controlled by internal PSU temperature. The diagram shows airflow from the terminal end toward the rear fan end. No fan-stop threshold or numerical external ventilation clearance is specified in these pages. External Output-Voltage Programming The standard PV range for NSP-1600-24 is 40-125% of nominal output voltage. A 15-125% range is available only by request; it is not assumed fitted to this model. Apply the external DC control voltage between CN1 pin 12 (PV) and pin 14 (-Vo(Signal)); this reference is non-isolated from the main output. Use the required remote- or local-sense connections below. The page 4 curve shows these external-voltage anchors: 1 V → 40%, 2 V → 63%, 3 V → 86%, 4.7 V → 125%. The diagram labels the PV relationship non-linear and includes a 0.4 V transition; use the plotted anchors rather than extrapolating one linear conversion. Adjust the permissible current with programmed voltage: the graph permits 100% rated current up to 100% nominal voltage, falling to 80% rated current at 125% voltage. Observe all other power, input and temperature limits. Constant-current limiting is documented as protection. These NSP-1600 pages do not specify a separate external PC input, an active parallel current-share connection or a permissible parallel-unit count; do not infer these from another power-supply family. Remote Control and Sense Connections For ON, short CN1 pin 3 (+5V-aux) to pin 4 (R.C); for OFF, open that connection. Pin 4 is rated 4.5-5.5 V for ON and -0.5 to +0.5 V for OFF, maximum input 5.5 V. Pin 3 is for this control function only. The isolated control reference is GND-aux, not the main negative output. External switch, optocoupler and relay examples are provided on page 4; those user control devices and their power sources are not listed as supplied accessories. Multiple-unit ON/OFF control is not evidence of output current sharing. Remote sense compensates load-wire drop up to 0.5 VDC: connect pin 15 (+RS) to load positive and pin 16 (-RS) to load negative. Twist the sense wires together to reduce noise pickup. When remote sense is unused, local-sense links are required: pin 15 (+RS) to pin 13 (+Vo(Signal)), and pin 16 (-RS) to pin 14 (-Vo(Signal)). Use the main copper bars for load current; the signal and sense pins cannot power the load. A CN1 mating-wire assembly is listed as a standard accessory. Before operation, verify the ON/local-sense connections against pages 4-7 rather than assuming arbitrary jumper pairs from a different model. CN1 Control Pin Assignment 1 / +12V-aux 10.6-13.2 VDC auxiliary output, maximum 0.8 A, referenced to GND-aux pin 2. Built-in ORing diodes; unaffected by remote ON/OFF. 2 / GND-aux Auxiliary and isolated control/alarm return; isolated from the main +Vo and -Vo output terminals. 3 / +5V-aux For remote ON/OFF use only; not a general-purpose auxiliary load supply. 4 / R.C Remote ON/OFF input. Short to +5V-aux pin 3 for ON (4.5-5.5 V); open for OFF (-0.5 to +0.5 V). Maximum input 5.5 V; isolated reference is GND-aux. 5 / DC-OK Isolated output-status signal referenced to GND-aux pin 2; see the alarm levels and thresholds below. 6 / T-ALARM Isolated temperature/fan-failure alarm output referenced to GND-aux pin 2; see the alarm levels below. 7, 8, 9 / A0, A1, A2 CANBus address lines; non-isolated, referenced to -Vo(Signal). Address settings require the manufacturer User Manual. 10, 11 / NC Reserved for future use; no user function is specified. 12 / PV External output-voltage programming input; non-isolated, referenced to -Vo(Signal) pin 14. 13 / +Vo(Signal) Positive local-sense signal; cannot be connected directly to the load. 14 / -Vo(Signal) Negative local-sense and function-reference signal; cannot be connected directly to the load. 15 / +RS Positive remote-sense input; connect to load positive, or to pin 13 for local sense. 16 / -RS Negative remote-sense input; connect to load negative, or to pin 14 for local sense. CN1 has 16 positions. The onboard header is HRS DF11-16DP-2DS or equivalent; the mating housing is HRS DF11-16DS or equivalent. Contacts are printed as HRS DF11-**SC or equivalent; ** is an unspecified variant, not a complete orderable contact code. Use the connector orientation in the mechanical drawing. A0/A1/A2 and PV are non-isolated references to -Vo(Signal); remote-control and alarm signals are isolated references to GND-aux. Alarms, LED and Auxiliary Output DC-OK pin 5 High 3.5-5.5 V when Vout ≤77% ±5%; low -0.5 to +0.5 V when Vout ≥80% ±5%. Reference: GND-aux pin 2. T-ALARM pin 6 High 3.5-5.5 V for overtemperature or fan failure (output OFF); low -0.5 to +0.5 V for normal internal temperature and fan operation (output ON). Reference: pin 2. LED indication Green: normal. Constant red: OTP, OLP or fan failure. Flashing red: internal temperature reaches 60°C; the unit still operates normally without entering OTP and sends a CANBus alarm. Alarm outputs are isolated TTL signals with a 10 mA maximum signal-current figure. The function text calls this a sink limit, whereas the pin table calls it a sourcing limit; confirm the required sink/source interface before connecting a direction-dependent load. The flashing-red 60°C figure is an internal temperature warning, not the ambient full-load limit or a specified fan-start temperature. The auxiliary supply is 12 V nominal (10.6-13.2 VDC), maximum 0.8 A, between CN1 pins 1 and 2. It contains ORing diodes and is not controlled by remote ON/OFF; do not extend this ORing statement to the main output. CANBus and CN2 Interface 1, 2, 3, 4 / NC Reserved for future use in the standard model. 5, 6 / -Vo(Signal) Negative local-sense/function-reference signal; cannot be connected directly to the load. 7 / CANH, 8 / CANL CANBus data lines; isolated and referenced to GND-aux. The pin table labels these as the CANBus-model interface. The family lists a built-in CANBus interface for control, settings, information reading, status monitoring and output trimming. Page 5 states CAN 2.0B with a maximum bus-speed figure printed as 250 kHz. Confirm the communication timing, address settings and commands in the manufacturer User Manual; this catalog does not provide those details. CN2 has 8 positions: onboard HRS DF11-8DP-2DS or equivalent, mating HRS DF11-8DS or equivalent, contacts HRS DF11-**SC or equivalent. The exact contact variant and a supplied CN2 cable quantity are not specified. Do not interchange CN1 and CN2 housings or invent a CAN ordering suffix.

External Output-Voltage Programming The standard PV range for NSP-1600-12 is 60-125% of nominal output voltage. A 15-125% range is available only by request; it is not assumed fitted to this model. Apply the external DC control voltage between CN1 pin 12 (PV) and pin 14 (-Vo(Signal)); this reference is non-isolated from the main output. Use the required remote- or local-sense connections below. The page 4 curve shows these external-voltage anchors: 1 V → 60%, 2 V → 78%, 3 V → 95%, 4.7 V → 125%.
