Model and Output Complete model MSP-1000-48 Model code MSP identifies the series; 1000 is the power-class designation; 48 identifies the nominal DC output voltage. Use the actual rating below for this model. Rated DC output 48 V / 21 A / 1008 W Current range 0–21 A Built-in voltage adjustment 46–56 V, using SVR1; respect the rated current and power limits. Ripple and noise 250 mVp-p maximum; 20 MHz bandwidth; 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Voltage tolerance ±1.0%, including setup tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±0.5% Efficiency 94% typical under the stated measurement conditions. Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. Input and Startup Input range 90–264 VAC, 127–370 VDC; universal AC input with active PFC. The low-line curve limits usable output. Frequency / surge tolerance 47–63 Hz; withstands 300 VAC surge input for 5 seconds. Power factor PF >0.95 at 230 VAC and >0.98 at 115 VAC, typical at full load. Input current 8.5 A at 115 VAC / 5 A at 230 VAC, typical. Inrush current 20 A at 115 VAC / 40 A at 230 VAC, typical; active inrush-current limiting is shown in the block diagram. Setup / rise time 1000 ms / 50 ms at 230 VAC; 2000 ms / 50 ms at 115 VAC, at full load. Hold-up time 16 ms at 230 VAC and 16 ms at 115 VAC, typical at full load. Setup time is measured at the first cold start; repeated power cycling can increase it. Below 40 VAC, performance may degrade and the final-equipment manufacturer must reconfirm basic safety and essential performance; this note does not extend the rated input range. Protection Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power; constant-current limiting with automatic recovery after the fault is removed. Over-voltage protection 58–65 V; output shuts down and requires re-powering to recover. Over-temperature protection Output shuts down and automatically recovers after temperature decreases. Remote Control, Standby and DC-OK Remote ON/OFF CN100 pin 3 (RC+) to pin 4 (RC-): short = ON; open = OFF. Remote-off no-load consumption <0.75 W with RC+ and RC- open. Standby auxiliary output 5 V / 0.3 A; 4.75–5.25 V, ±5% tolerance, 50 mVp-p maximum ripple. AUX pin 2 is referenced to AUXG pin 1 and is not switched off by remote ON/OFF. DC-OK signal TTL output, referenced to CN100 GND pin 6 or 8: 3.3–5.6 V when the supply is ON; 0–1 V when OFF. Remote sense Up to 0.5 V load-wiring drop compensation. Connect +S pin 9 to load positive and -S pin 10 to load negative; twist the sense pair to minimize pickup. CN100 Control Connector Pin 1 — AUXG Auxiliary-output ground. Pin 2 — AUX Auxiliary voltage output, referenced to pin 1; 0.3 A maximum. Pins 3 / 4 — RC+ / RC- Remote-control input and return: short = ON; open = OFF. Pin 5 — CS Current-share signal; interconnect CS pins when using the supported parallel arrangement. Pins 6 / 8 — GND Connected to output -V; DC-OK signal return. Pin 7 — DC-OK TTL status signal, HIGH when the supply turns on; referenced to pin 8. Pins 9 / 10 — +S / -S Positive and negative remote sense; connect as shown in the model-specific wiring diagram. Parallel Operation Use short, large-diameter output wiring. Maximum total parallel current = rated current per unit × number of units × 0.9. Up to four units are shown; follow the complete manufacturer interconnection diagram, including CS, GND and sense wiring. The output-voltage difference between parallel units must be less than 0.2 V. Below 5% of the total rated current, current sharing may not be fully balanced. The catalogue describes the family as up to 4000 W (3+1), but the model-specific current formula and derating limits still apply. Cooling, Derating and Environment Temperature and load The specification lists -40 to +70°C subject to the derating curve. Horizontal mounting, 24/48 V branch: 100% load through +60°C, declining to 60% at +70°C. Input-voltage derating At 60 Hz, the input curve rises from 80% load at 90 VAC to 100% at 200 VAC, remaining at 100% through 264 VAC. Cooling / fan control Built-in cooling fan with ON/OFF control by internal NTC RT50 or 30% load minimum, as stated in the specification. The catalogue does not give a numeric ambient switching temperature for this sensor. Working humidity 20–90% RH, non-condensing. Storage -40 to +85°C and 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 5 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Altitude derating For this fan-cooled supply, reduce the permissible ambient temperature by 5°C per additional 1000 m above 2000 m (6500 ft), as specified in the catalogue note. Temperature and low-input-voltage limits apply together; the upper working-temperature figure does not mean full rated power is available at every input voltage.

  MEAN WELL MSP-1000 series: Medical AC/DC Power Supply - MSP-1000-12

  MEAN WELL MSP-1000-12 is a single-output enclosed medical AC/DC power supply rated at 12 V, 80 A and 960 W. It supports a maximum 1000 W for 3 seconds; 960 W remains the continuous rating. Active current sharing is available under the specified parallel-operation limits. Select the load using the output rating and both ambient-temperature and input-voltage derating curves. Product Datasheet Download MEAN WELL MSP-1000 Datasheet (PDF) The MSP-1000 section is on PDF pages 17, 18, 19, 20, 21, 22. Refer to the complete mechanical drawings and notes when planning installation. Model and Output Complete model MSP-1000-12 Model code MSP identifies the series; 1000 is the power-class designation; 12 identifies the nominal DC output voltage. Use the actual rating below for this model. Rated DC output 12 V / 80 A / 960 W Current range 0–80 A Built-in voltage adjustment 11–14 V, using SVR1; respect the rated current and power limits. Ripple and noise 150 mVp-p maximum; 20 MHz bandwidth; 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Voltage tolerance ±2.0%, including setup tolerance, line regulation and load regulation. Line / load regulation ±0.5% / ±2.0% Efficiency 91.5% typical under the stated measurement conditions. Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. Maximum output power is 1000 W for 3 seconds; do not treat this short-duration figure as the continuous output rating. Input and Startup Input range 90–264 VAC, 127–370 VDC; universal AC input with active PFC. The low-line curve limits usable output. Frequency / surge tolerance 47–63 Hz; withstands 300 VAC surge input for 5 seconds. Power factor PF >0.95 at 230 VAC and >0.98 at 115 VAC, typical at full load. Input current 8.5 A at 115 VAC / 5 A at 230 VAC, typical. Inrush current 20 A at 115 VAC / 40 A at 230 VAC, typical; active inrush-current limiting is shown in the block diagram. Setup / rise time 1000 ms / 50 ms at 230 VAC; 2000 ms / 50 ms at 115 VAC, at full load. Hold-up time 16 ms at 230 VAC and 16 ms at 115 VAC, typical at full load. Setup time is measured at the first cold start; repeated power cycling can increase it. Below 40 VAC, performance may degrade and the final-equipment manufacturer must reconfirm basic safety and essential performance; this note does not extend the rated input range. Protection Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power; constant-current limiting with automatic recovery after the fault is removed. Over-voltage protection 14.5–16.5 V; output shuts down and requires re-powering to recover. Over-temperature protection Output shuts down and automatically recovers after temperature decreases. Remote Control, Standby and DC-OK Remote ON/OFF CN100 pin 3 (RC+) to pin 4 (RC-): short = ON; open = OFF. Remote-off no-load consumption <0.75 W with RC+ and RC- open. Standby auxiliary output 5 V / 0.3 A; 4.75–5.25 V, ±5% tolerance, 50 mVp-p maximum ripple. AUX pin 2 is referenced to AUXG pin 1 and is not switched off by remote ON/OFF. DC-OK signal TTL output, referenced to CN100 GND pin 6 or 8: 3.3–5.6 V when the supply is ON; 0–1 V when OFF. Remote sense Up to 0.5 V load-wiring drop compensation. Connect +S pin 9 to load positive and -S pin 10 to load negative; twist the sense pair to minimize pickup. CN100 Control Connector Pin 1 — AUXG Auxiliary-output ground. Pin 2 — AUX Auxiliary voltage output, referenced to pin 1; 0.3 A maximum. Pins 3 / 4 — RC+ / RC- Remote-control input and return: short = ON; open = OFF. Pin 5 — CS Current-share signal; interconnect CS pins when using the supported parallel arrangement. Pins 6 / 8 — GND Connected to output -V; DC-OK signal return. Pin 7 — DC-OK TTL status signal, HIGH when the supply turns on; referenced to pin 8. Pins 9 / 10 — +S / -S Positive and negative remote sense; connect as shown in the model-specific wiring diagram. Parallel Operation Use short, large-diameter output wiring. Maximum total parallel current = rated current per unit × number of units × 0.9. Up to four units are shown; follow the complete manufacturer interconnection diagram, including CS, GND and sense wiring. The output-voltage difference between parallel units must be less than 0.2 V. Below 5% of the total rated current, current sharing may not be fully balanced. The catalogue describes the family as up to 4000 W (3+1), but the model-specific current formula and derating limits still apply. Cooling, Derating and Environment Temperature and load The specification lists -40 to +70°C subject to the derating curve. Horizontal mounting, 12/15 V branch: 100% load through +50°C, declining to 60% at +60°C; the plotted branch ends at +60°C. Input-voltage derating At 60 Hz, the input curve rises from 80% load at 90 VAC to 100% at 200 VAC, remaining at 100% through 264 VAC. Cooling / fan control Built-in cooling fan with ON/OFF control by internal NTC RT50 or 30% load minimum, as stated in the specification. The catalogue does not give a numeric ambient switching temperature for this sensor. Working humidity 20–90% RH, non-condensing. Storage -40 to +85°C and 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 5 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Altitude derating For this fan-cooled supply, reduce the permissible ambient temperature by 5°C per additional 1000 m above 2000 m (6500 ft), as specified in the catalogue note. Temperature and low-input-voltage limits apply together; the upper working-temperature figure does not mean full rated power is available at every input voltage. Dimensions, Terminals and Installation Overall dimensions 218 × 105 × 63.5 mm (L × W × H); case 977. Mechanical drawing tolerance ±0.5 mm. Mounting-hole labels Bottom: 4-M4 L=6; sides: 8-M4 L=4 (both sides). Use the complete drawing for thread engagement and hole positions; these labels are not accessory ordering codes. Hole-position references The drawing marks 152.4 mm spacing, a 32.8 mm end reference, and the 20.75/63.5 mm transverse references; side-view references include 38.3 and 12.5 mm. Follow the full drawing for each datum. AC input terminals 1 = AC/L; 2 = AC/N; 3 = FG protective earth. DC output terminals 1–3 = +V; 4–6 = -V. Confirm polarity against this model’s terminal diagram. Terminal drawing dimensions The AC side marks 10 and 8.2 mm; the DC side marks 11 and 9.2 mm. These are drawing dimensions at their indicated locations, not a claim that every value is terminal pitch. Terminal projections AC-input side: 12 mm maximum; DC-output side: 18 mm maximum. Airflow and adjustment The mechanical drawing arrow points outward at the fan/input end. Keep the indicated airflow path unobstructed. The drawing identifies the LED and SVR1 output-voltage adjustment. Connector Mating Parts CN100 board connector HRS DF11-10DP-2DS or equivalent.

For this MSP-600 voltage version, the output-voltage difference between parallel units must be less than 2%. The diagram interconnects +S, -S, CS and GND. For more than four units, consult the manufacturer. Below 2% of rated load, only one master unit may operate; other slave units may enter standby with their output LED and relay off. This minimum-load condition is part of the parallel-operation instructions. Cooling, Derating and Environment Temperature and load The specification lists -40 to +70°C subject to the derating curve. Horizontal mounting: the plotted load remains at 100% from -40°C through +50°C, then declines to 50% at +70°C. Input-voltage derating At 60 Hz, the input curve rises from 80% load at 85 VAC to 100% at 100 VAC, remaining at 100% through 264 VAC. Cooling / fan control Built-in cooling fan with ON/OFF control; fan ON at 35±15% load or when internal sensor RTH2 reaches at least 50°C. The sensor temperature is not an ambient-temperature rating. Working humidity 20–90% RH, non-condensing. Storage -40 to +85°C and 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 5 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Altitude derating For this fan-cooled supply, reduce the permissible ambient temperature by 5°C per additional 1000 m above 2000 m (6500 ft), as specified in the catalogue note. Temperature and low-input-voltage limits apply together; the upper working-temperature figure does not mean full rated power is available at every input voltage.

Ripple and noise 150 mVp-p maximum; 20 MHz bandwidth; 12-inch twisted pair terminated with parallel 0.1 µF and 47 µF capacitors. Voltage tolerance ±1.0%, including setup tolerance, line regulation and load regulation. Line / load regulation ±0.2% / ±0.5% Efficiency 88% typical under the stated measurement conditions. Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. Input and Startup Input range 85–264 VAC, 120–370 VDC; universal AC input with active PFC. The low-line curve limits usable output. Frequency / surge tolerance 47–63 Hz; withstands 300 VAC surge input for 5 seconds. Power factor PF >0.93 at 230 VAC and >0.99 at 115 VAC, typical at full load. Input current 8.5 A at 115 VAC / 5 A at 230 VAC, typical. Inrush current 35 A at 115 VAC / 80 A at 230 VAC, typical; active inrush-current limiting is shown in the block diagram. Setup / rise time 1000 ms / 50 ms at 230 VAC; 2500 ms / 50 ms at 115 VAC, at full load. Hold-up time 16 ms at 230 VAC and 16 ms at 115 VAC, typical at full load. Setup time is measured at the first cold start; repeated power cycling can increase it. Below 40 VAC, performance may degrade and the final-equipment manufacturer must reconfirm basic safety and essential performance; this note does not extend the rated input range. Protection Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power; constant-current limiting with automatic recovery after the fault is removed. Over-voltage protection 30–34.8 V; output shuts down and requires re-powering to recover. Over-temperature protection Output shuts down and automatically recovers after temperature decreases. Remote Control, Standby and DC-OK Remote ON/OFF CN100 pin 3 (RC+) to pin 4 (RC-): short or 0–0.8 V = OFF; open or 4–10 V = ON.

Parallel-operation Boundary The active current-sharing arrangement in this catalogue is limited to the 24 V, 36 V and 48 V MSP-600 versions. Do not apply that function to this model merely because the common connector drawing labels pin 5 as CS. Cooling, Derating and Environment Temperature and load The specification lists -40 to +70°C subject to the derating curve. Horizontal mounting: the plotted load remains at 100% from -40°C through +50°C, then declines to 50% at +70°C. Input-voltage derating At 60 Hz, the input curve rises from 80% load at 85 VAC to 100% at 100 VAC, remaining at 100% through 264 VAC. Cooling / fan control Built-in cooling fan with ON/OFF control; fan ON at 35±15% load or when internal sensor RTH2 reaches at least 50°C. The sensor temperature is not an ambient-temperature rating. Working humidity 20–90% RH, non-condensing. Storage -40 to +85°C and 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 5 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Altitude derating For this fan-cooled supply, reduce the permissible ambient temperature by 5°C per additional 1000 m above 2000 m (6500 ft), as specified in the catalogue note. Temperature and low-input-voltage limits apply together; the upper working-temperature figure does not mean full rated power is available at every input voltage.

Setup time is measured at the first cold start; repeated power cycling can increase it. Below 40 VAC, performance may degrade and the final-equipment manufacturer must reconfirm basic safety and essential performance; this note does not extend the rated input range. Protection Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power; constant-current limiting with automatic recovery after the fault is removed. Over-voltage protection 3.96–4.62 V; output shuts down and requires re-powering to recover. Over-temperature protection Output shuts down and automatically recovers after temperature decreases. Remote Control, Standby and DC-OK Remote ON/OFF CN100 pin 3 (RC+) to pin 4 (RC-): short or 0–0.8 V = OFF; open or 4–10 V = ON. Remote-off no-load consumption <0.8 W with RC+ and RC- shorted or at 0–0.8 V. Standby auxiliary output 5 V / 0.3 A; 4.75–5.25 V, ±5% tolerance, 50 mVp-p maximum ripple. AUX pin 2 is referenced to AUXG pin 1 and is not switched off by remote ON/OFF. DC-OK signal TTL output, referenced to CN100 GND pin 6 or 8: 3.3–5.6 V when the supply is ON; 0–1 V when OFF. Remote sense Up to 0.5 V load-wiring drop compensation. Connect +S pin 9 to load positive and -S pin 10 to load negative; twist the sense pair to minimize pickup. CN100 Control Connector Pin 1 — AUXG Auxiliary-output ground. This signal return is isolated from the +V/-V output terminals. Pin 2 — AUX Auxiliary voltage output, referenced to pin 1; 0.3 A maximum. Pins 3 / 4 — RC+ / RC- Remote-control input and return: short = OFF; open = ON. Pin 5 — CS CS is identified in the common connector table; active current sharing is specified only for MSP-600-24, -36 and -48, not this voltage version. Pins 6 / 8 — GND Connected to output -V; DC-OK signal return. Pin 7 — DC-OK TTL status signal, HIGH when the supply turns on; referenced to pin 8. Pins 9 / 10 — +S / -S Positive and negative remote sense; connect as shown in the model-specific wiring diagram. Parallel-operation Boundary The active current-sharing arrangement in this catalogue is limited to the 24 V, 36 V and 48 V MSP-600 versions. Do not apply that function to this model merely because the common connector drawing labels pin 5 as CS. Cooling, Derating and Environment Temperature and load The specification lists -40 to +70°C subject to the derating curve. Horizontal mounting: the plotted load remains at 100% from -40°C through +50°C, then declines to 50% at +70°C. Input-voltage derating At 60 Hz, the input curve rises from 80% load at 85 VAC to 100% at 100 VAC, remaining at 100% through 264 VAC. Cooling / fan control Built-in cooling fan with ON/OFF control; fan ON at 35±15% load or when internal sensor RTH2 reaches at least 50°C. The sensor temperature is not an ambient-temperature rating. Working humidity 20–90% RH, non-condensing. Storage -40 to +85°C and 10–95% RH, non-condensing. Temperature coefficient ±0.03%/°C over 0–50°C. Vibration 10–500 Hz, 5 G; 10 minutes per cycle and 60 minutes along each X, Y and Z axis. Altitude derating For this fan-cooled supply, reduce the permissible ambient temperature by 5°C per additional 1000 m above 2000 m (6500 ft), as specified in the catalogue note. Temperature and low-input-voltage limits apply together; the upper working-temperature figure does not mean full rated power is available at every input voltage. Dimensions, Terminals and Installation Overall dimensions 218 × 105 × 63.5 mm (L × W × H); case 977A. Mechanical drawing tolerance ±1 mm. Mounting-hole labels Bottom: 4-M4 L=6; sides: 8-M4 L=4 (both sides). Use the complete drawing for thread engagement and hole positions; these labels are not accessory ordering codes.

Follow the full drawing for each datum. AC input terminals 1 = AC/L; 2 = AC/N; 3 = FG protective earth. DC output terminals 1–3 = -V; 4–6 = +V. Confirm polarity against this model’s terminal diagram. Terminal drawing dimensions The AC side marks 10 and 8.2 mm; the DC side marks 11 and 9.2 mm. These are drawing dimensions at their indicated locations, not a claim that every value is terminal pitch. Terminal projections AC-input side: 12 mm maximum; DC-output side: 18 mm maximum. Airflow and adjustment The mechanical drawing arrow points from the fan/input end toward the DC-output end. Keep the indicated airflow path unobstructed.

These pages do not establish a MOPP patient-protection rating or certify the completed medical equipment. Match the required insulation, leakage, grounding and final-system safety evaluation to the intended application. Protection and Cooling Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power, using constant-current limiting; automatic recovery after the fault is removed. Overvoltage 57.6–67.2 V threshold for this model; shuts down the output, with re-powering required to recover. Overtemperature Shuts down the output; automatic recovery after temperature falls. Controlled cooling fan Built-in fan ON/OFF control: fan turns on at a typical load threshold of 20 ±10%, or when internal thermistor RTH2 reaches at least 50°C. RTH2 is not the ambient-temperature rating. Ambient derating Horizontal mounting: 100% load from −40°C to +50°C, decreasing linearly to 50% at +70°C. The operating range is −40°C to +70°C, subject to this curve. Input-voltage derating At 60 Hz, the curve rises from 80% load at 85 VAC to 100% at 100 VAC, then remains at 100% through 264 VAC.

Observe the rated current and rated power limits when adjusting output voltage. Ripple and noise 150 mVp-p maximum; measured with 20 MHz bandwidth, a 12-inch twisted pair and 0.1 µF + 47 µF parallel capacitors. Voltage accuracy Voltage tolerance ±1.0%; line regulation ±0.2%; load regulation ±0.5%. Tolerance includes setup, line and load regulation. Typical efficiency 88%, at the catalogue default test conditions. Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. The family name is not a substitute for this exact model’s output rating. Input and Timing Normal input range 85–264 VAC or 120–370 VDC; AC frequency 47–63 Hz. Apply low-input derating. Active PFC Typical PF >0.95 at 230 VAC and >0.99 at 115 VAC, both at full load. Typical AC current 5 A at 115 VAC; 2.4 A at 230 VAC. Inrush / surge withstand Typical inrush 35 A at 115 VAC and 70 A at 230 VAC. Active inrush-current limiting is shown in the block diagram. Withstands 300 VAC surge input for 5 seconds; 300 VAC is not the continuous input rating. Setup / rise time 1000 ms / 100 ms at 230 VAC; 2500 ms / 100 ms at 115 VAC, at full load. Hold-up time 16 ms typical at 230 VAC and 16 ms typical at 115 VAC, at full load. No-load consumption The feature list states no-load input power below 0.6 W. Note 6 specifies below 0.5 W with the main output remotely OFF: RC+ to RC− at 0–0.8 V or shorted. Setup time is measured at the first cold start. Repeated ON/OFF switching may increase setup time. Below 40 VAC, the catalogue warns of possible performance degradation and requires the final-equipment manufacturer to reconfirm basic safety and essential performance. This is an abnormal low-input condition, not an extension of the normal 85–264 VAC operating range. Medical Isolation, Leakage and Approval Scope Medical isolation level Primary-to-secondary: 2 × MOOP; primary-to-earth: 1 × MOOP. Secondary-to-earth: 1 × MOOP. MOOP stands for means of operator protection. Leakage at 264 VAC Earth leakage <300 µA; touch leakage <100 µA.

Apply the model-specific input, leakage and derating limits below. Product Datasheet Download MEAN WELL MSP-450 Datasheet (PDF) The MSP-450 section is on PDF pages 10, 11, 12. Refer to the complete mechanical drawings and notes when planning installation. Exact Model and Output Ratings Complete model MSP-450-7.5: MSP-450 single-output enclosed medical-type AC/DC power supply; -7.5 identifies the nominal 7.5 VDC output. Catalogue revision 2025-12-05. Rated output 7.5 VDC; 60 A; 450 W. Current range: 0–60 A. These are the exact model ratings, subject to the derating limits below. Output voltage adjustment 6.8–9 V using SVR. Observe the rated current and rated power limits when adjusting output voltage. Ripple and noise 100 mVp-p maximum; measured with 20 MHz bandwidth, a 12-inch twisted pair and 0.1 µF + 47 µF parallel capacitors. Voltage accuracy Voltage tolerance ±2.0%; line regulation ±0.5%; load regulation ±1.0%. Tolerance includes setup, line and load regulation. Typical efficiency 86.5%, at the catalogue default test conditions. Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. The family name is not a substitute for this exact model’s output rating. Input and Timing Normal input range 85–264 VAC or 120–370 VDC; AC frequency 47–63 Hz. Apply low-input derating. Active PFC Typical PF >0.95 at 230 VAC and >0.99 at 115 VAC, both at full load. Typical AC current 5 A at 115 VAC; 2.4 A at 230 VAC. Inrush / surge withstand Typical inrush 35 A at 115 VAC and 70 A at 230 VAC. Active inrush-current limiting is shown in the block diagram. Withstands 300 VAC surge input for 5 seconds; 300 VAC is not the continuous input rating. Setup / rise time 1000 ms / 100 ms at 230 VAC; 2500 ms / 100 ms at 115 VAC, at full load. Hold-up time 16 ms typical at 230 VAC and 16 ms typical at 115 VAC, at full load. No-load consumption The feature list states no-load input power below 0.6 W. Note 6 specifies below 0.5 W with the main output remotely OFF: RC+ to RC− at 0–0.8 V or shorted. Setup time is measured at the first cold start. Repeated ON/OFF switching may increase setup time. Below 40 VAC, the catalogue warns of possible performance degradation and requires the final-equipment manufacturer to reconfirm basic safety and essential performance. This is an abnormal low-input condition, not an extension of the normal 85–264 VAC operating range. Medical Isolation, Leakage and Approval Scope Medical isolation level Primary-to-secondary: 2 × MOOP; primary-to-earth: 1 × MOOP. Secondary-to-earth: 1 × MOOP. MOOP stands for means of operator protection. Leakage at 264 VAC Earth leakage <300 µA; touch leakage <100 µA. Listed safety approvals IEC60601-1:2005+A1+A2; ANSI/AAMI ES60601-1:2005+A2; CAN/CSA C22.2 No.60601-1:2014+A2; EAC TP TC004. Design references by request BS EN/EN60335-1 and BS EN/EN62368-1 are listed as design references, by request. Withstand voltage Input-to-output: 4 kVAC; input-to-FG: 2 kVAC; output-to-FG: 0.5 kVAC. Insulation resistance 100 MΩ minimum for input/output, input/FG and output/FG, tested at 500 VDC, 25°C and 70% RH. The stated insulation classification is MOOP. These pages do not establish a MOPP patient-protection rating or certify the completed medical equipment. Match the required insulation, leakage, grounding and final-system safety evaluation to the intended application. Protection and Cooling Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power, using constant-current limiting; automatic recovery after the fault is removed. Overvoltage 9.4–10.9 V threshold for this model; shuts down the output, with re-powering required to recover. Overtemperature Shuts down the output; automatic recovery after temperature falls. Controlled cooling fan Built-in fan ON/OFF control: fan turns on at a typical load threshold of 20 ±10%, or when internal thermistor RTH2 reaches at least 50°C. RTH2 is not the ambient-temperature rating. Ambient derating Horizontal mounting: 100% load from −40°C to +50°C, decreasing linearly to 50% at +70°C. The operating range is −40°C to +70°C, subject to this curve. Input-voltage derating At 60 Hz, the curve rises from 80% load at 85 VAC to 100% at 100 VAC, then remains at 100% through 264 VAC. Altitude derating For this fan-cooled model, reduce the allowed ambient temperature by 5°C per additional 1000 m above 2000 m. Apply input-voltage, temperature and output-rating limits together. Keep the indicated fan inlet/outlet and surrounding airflow path unobstructed; verify cooling in the final enclosure. No numerical mounting-clearance distance is specified in these catalogue pages. Standby, Remote Control and DC OK Standby output 5 V, 0.3 A maximum; tolerance ±5% (4.75–5.25 V), ripple 50 mVp-p maximum. AUX is not switched by the main-output remote ON/OFF control. Standby reference AUX pin 3 returns to AUXG pin 4. AUXG is isolated from the main +V/−V terminals; do not substitute the DC-OK ground. Remote ON/OFF Between RC+ pin 1 and RC− pin 2: 4–10 V or open contact = power ON; 0–0.8 V or short contact = power OFF. DC-OK signal DC-OK pin 5 is referenced to GND pin 6, which connects to main −V. TTL high when the PSU is ON: 3.3–5.6 V; OFF: 0–1 V. Remote sense Connect +S pin 7 to the positive load terminal and −S pin 8 to the negative load terminal.

Exact Model and Output Ratings Complete model MSP-300-24: MSP-300 single-output enclosed medical-type AC/DC power supply; -24 identifies the nominal 24 VDC output. Catalogue revision 2026-02-09. Rated output 24 VDC; 14 A; 336 W. Current range: 0–14 A. These are the exact model ratings, subject to the derating limits below. Output voltage adjustment 21.6–28.8 V using SVR. Observe the rated current and rated power limits when adjusting output voltage. Ripple and noise 150 mVp-p maximum; measured with 20 MHz bandwidth, a 12-inch twisted pair and 0.1 µF + 47 µF parallel capacitors. Voltage accuracy Voltage tolerance ±1.0%; line regulation ±0.2%; load regulation ±0.5%. Tolerance includes setup, line and load regulation. Typical efficiency 87%, at the catalogue default test conditions. Unless otherwise stated, specifications are measured at 230 VAC input, rated load and 25°C ambient. The family name is not a substitute for this exact model’s output rating. Input and Timing Normal input range 85–264 VAC or 120–370 VDC; AC frequency 47–63 Hz. Apply low-input derating. Active PFC Typical PF >0.95 at 230 VAC and >0.99 at 115 VAC, both at full load. Typical AC current 4.5 A at 115 VAC; 2.25 A at 230 VAC. Inrush / surge withstand Typical inrush 35 A at 115 VAC and 70 A at 230 VAC. Active inrush-current limiting is shown in the block diagram. Withstands 300 VAC surge input for 5 seconds; 300 VAC is not the continuous input rating. Setup / rise time 1000 ms / 50 ms at 230 VAC; 2500 ms / 50 ms at 115 VAC, at full load. Hold-up time 16 ms typical at 230 VAC and 16 ms typical at 115 VAC, at full load. No-load consumption No-load input power below 0.5 W with the main output remotely OFF: RC+ to RC− at 0–0.8 V or shorted. Medical Isolation, Leakage and Approval Scope Medical isolation level Primary-to-secondary: 2 × MOOP; primary-to-earth: 1 × MOOP. MOOP stands for means of operator protection. Leakage at 264 VAC Earth leakage <450 µA; touch leakage <100 µA. Listed safety approvals IEC60601-1:2005+A1+A2; ANSI/AAMI ES60601-1:2005+A2; CAN/CSA C22.2 No.60601-1:2014+A2; EAC TP TC004. Design references by request BS EN/EN60335-1 and BS EN/EN62368-1 are listed as design references, by request. Withstand voltage Input-to-output: 4 kVAC; input-to-FG: 2 kVAC; output-to-FG: 0.5 kVAC. Insulation resistance 100 MΩ minimum for input/output, input/FG and output/FG, tested at 500 VDC, 25°C and 70% RH. The stated insulation classification is MOOP. These pages do not establish a MOPP patient-protection rating or certify the completed medical equipment. Match the required insulation, leakage, grounding and final-system safety evaluation to the intended application. Protection and Cooling Short circuit / overload Short-circuit protection is listed. Overload threshold: 105–135% of rated output power, using constant-current limiting; automatic recovery after the fault is removed. Overvoltage 30–34.8 V threshold for this model; shuts down the output, with re-powering required to recover. Overtemperature Shuts down the output; automatic recovery after temperature falls. Controlled cooling fan Built-in fan ON/OFF control: fan turns on at a typical load threshold of 35 ±15%, or when internal thermistor RTH2 reaches at least 50°C. RTH2 is not the ambient-temperature rating. Ambient derating Horizontal mounting: 100% load from −40°C to +50°C, decreasing linearly to 50% at +70°C. The operating range is −40°C to +70°C, subject to this curve. Input-voltage derating At 60 Hz, the curve rises from 80% load at 85 VAC to 100% at 100 VAC, then remains at 100% through 264 VAC. Altitude derating For this fan-cooled model, reduce the allowed ambient temperature by 5°C per additional 1000 m above 2000 m. Apply input-voltage, temperature and output-rating limits together. Keep the indicated fan inlet/outlet and surrounding airflow path unobstructed; verify cooling in the final enclosure. No numerical mounting-clearance distance is specified in these catalogue pages. Standby, Remote Control and DC OK Standby output 5 V, 0.3 A maximum; tolerance ±5% (4.75–5.25 V), ripple 50 mVp-p maximum. AUX is not switched by the main-output remote ON/OFF control. Standby reference AUX pin 1 returns to AUXG pin 2. AUXG is isolated from the main +V/−V terminals; do not substitute the DC-OK ground. Remote ON/OFF Between RC+ pin 6 and RC− pin 4: 4–10 V or open contact = power ON; 0–0.8 V or short contact = power OFF. DC-OK signal DC-OK pin 3 is referenced to GND pin 5, which connects to main −V. TTL high when the PSU is ON: 3.3–5.6 V; OFF: 0–1 V. Remote sense Connect +S pin 7 to the positive load terminal and −S pin 8 to the negative load terminal. Twist +S and −S together; maximum line-drop compensation is 0.5 V. Use the complete function and connection drawings on PDF pages 8–9. DC-OK is a TTL status output, not a dry relay contact; no additional contact-current or sourcing-current rating is specified here. The documented functions for this family are standby, remote ON/OFF, DC OK and remote sense. No active current-sharing or parallel-unit count is specified for these models. Power Terminals and CN100 Pin Assignment Power terminals 1 / 2 / 3 AC/L / AC/N / FG (frame ground), respectively. Power terminals 4–5 / 6–7 4 and 5: DC −V; 6 and 7: DC +V. CN100 pin 1 — AUX 4.75–5.25 V auxiliary output, maximum 0.3 A, referenced to AUXG pin 2; remains available independently of remote ON/OFF control. CN100 pin 2 — AUXG Auxiliary return, isolated from the main +V and −V output terminals. CN100 pin 3 — DC-OK TTL status output referenced to GND pin 5; high when the PSU turns on. CN100 pin 4 — RC- Remote-control ground. CN100 pin 5 — GND DC-OK signal return; connected to the main −V output. CN100 pin 6 — RC+ Remote ON/OFF control input relative to RC− pin 4; an open contact enables the main output and a short disables it. CN100 pin 7 — +S Positive remote-sense lead to the positive load terminal; use a twisted pair with −S. CN100 pin 8 — -S Negative remote-sense lead to the negative load terminal; use a twisted pair with +S. Pin numbers refer to the actual connector orientation shown on PDF page 7. Verify polarity and the separate return functions before wiring. Mating Connector and Installation Parts Board connector CN100: HRS DF11-8DP-2DS or equivalent, as printed in the catalogue. Mating housing HRS DF11-8DS or equivalent, as printed. Contact reference HRS DF11-**SC or equivalent. The asterisks are a contact-family placeholder, not a complete orderable contact suffix. Confirm the complete mating-housing/contact variant, wire size and crimp tooling with the connector supplier before ordering. The catalogue does not specify an included harness quantity, a complete contact suffix or an accessory-kit order code; no inclusion is implied by the drawing.
