产品特点 FEATURES

1 Modular design with 6 slots (NMP1K2 model) supporting up to 1200W total output power, compatible with interchangeable NMS-240 (single output) and NMD-240 (dual output) modules

2 Wide input voltage range: 90~264VAC or 120~370VDC, suitable for global applications

3 Compliance with medical (2x MOPP isolation) and ITE safety standards, ensuring reliability in critical use cases

4 Rich functional features: remote sense (compensates up to 0.5V wiring drop), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), temperature alarm (T-Alarm signal)

5 Support for global or local ON/OFF control: global control via RC1 pin, local control via module RC2/RC3 pins

6 Current sharing capability for parallel operation of NMS-240 modules, enabling higher power output with balanced load distribution

7 High efficiency (up to 91% for H/K modules at nominal 24V/48V), reducing energy loss and heat generation

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices, patient monitoring systems, and other medical devices requiring compliant power supplies

2 Industrial automation: PLC systems, motor drives, sensors, and control panels needing stable modular power

3 Test and measurement instruments: Laboratory equipment, signal generators, and analyzers requiring precise voltage/current control

4 Communication infrastructure: Base stations, network switches, and routers needing reliable high-power modular power

5 Data centers and server racks: Modular power distribution for servers and storage devices

6 Custom electronic systems: Prototyping and production of devices needing flexible voltage configurations

注意事项 PRECAUTIONS

1 Ensure the shorting connector (RC1 to GND-P) is properly installed for global ON/OFF control; otherwise, the power supply will have no output

2 Follow derating guidelines: When output voltage is below 12V and ambient temperature is between -15°C to -30°C, derate output current to 90% of rated value; refer to derating curves for other conditions

3 For parallel operation of NMS-240 modules: Connect CS pins of all modules, ensure output voltage difference between modules is less than 0.2V, and do not exceed maximum slot count (6 for NMP1K2)

4 Use twisted pairs for remote sense (±S pins) to minimize interference; remote sense compensates up to 0.5V wiring voltage drop

5 When programming output voltage/current (PV/PC pins), adhere to specified voltage ranges and do not exceed module limits

6 Handle over-temperature alarms promptly: T-Alarm signal (high level) indicates internal temperature exceeds limits; reduce load or improve cooling to prevent shutdown

7 Do not use output current programming (PC) function when modules are in parallel operation

8 Ensure proper grounding and wiring to avoid electrical hazards and maintain performance
