产品特点 FEATURES

1 Modular design with 4 slots (NMP650 series) for flexible output configuration

2 Wide input voltage range:90~264VAC /120~370VDC; frequency range:47~63Hz

3 High power factor:PF>0.95 (230VAC) / PF>0.98 (115VAC) at full load

4 Complies with medical (2x MOPP between primary and secondary) and ITE safety standards

5 Supports multiple output modules (NMS-240 single output:5V/36A,12V/20A,24V/10A,48V/5A; NMD-240 dual output: up to30V@5A each, combined 240W max)

6 Built-in protection functions: overload (constant current limiting), overvoltage (shut down, repower to recover), overtemperature (shut down, auto recover after cooling)

7 Equipped with remote control (ON/OFF), DC OK signal (TTL level), auxiliary power output (5V/1.5A for NMP650)

8 Supports current sharing for parallel operation of modules

9 High efficiency (up to91% for H/K modules at nominal 24V/48V full load)

注意事项 PRECAUTIONS

1 Ensure the shorting connector accessory (from RC1 to GND-P) is assembled for normal operation

2 Derate output current to90% of rated value when output voltage <12V and ambient temperature is between -15°C and -30°C

3 Use remote sense function to compensate for voltage drop on load wiring (up to0.5V)

4 When parallelizing modules for current sharing: connect CS pins mutually, ensure output voltage difference <0.2V among modules, total output power not exceeding650W (NMP650), and do not use PC (output current programming) function

5 Follow ON/OFF control logic: global ON/OFF via RC1 (short to GND-P for ON), local ON/OFF via RC2 (open for ON, short for OFF for NMS-240)

6 Avoid exceeding operating temperature range (-30°C to +70°C) without proper derating

7 Use short, large-diameter wiring for parallel connections to ensure current balance
