产品特点 FEATURES

1 Modular design: NMP1K2 supports up to 6 slots, each module (NMS-240 single/ NMD-240 dual) delivers up to 240W, flexible configuration for different voltage needs (5V,12V,24V,48V etc.)

2 Wide input range: AC 90~264V or DC120~370V, suitable for global use

3 High efficiency: Up to 91% at full load (with H/K module at 24V/48V nominal)

4 Multiple safety certifications: Complies with IEC60601-1 (medical, 2x MOPP isolation), IEC62368-1, UL62368-1 etc.

5 Rich protection functions: Overload (OLP), over voltage (OVP), over temperature (OTP) protection; OTP shuts down output and recovers automatically when temp drops

6 Advanced control features: Global/local ON/OFF control, remote sense (compensates voltage drop up to 0.5V), output voltage/current programming (PV/PC pins), DC OK signal (TTL level for output status), current sharing (CS pin for parallel operation balance)

7 Auxiliary power output: +5V-AUX_P (2A for NMP1K2,1.5A for NMP650) and Vcc2 (5V/10mA for modules)

8 Compact size: NMP1K2 front-end is 250*127*41mm (L*W*H), easy to integrate into equipment

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety standards (like patient monitors, diagnostic equipment) due to 2x MOPP isolation

2 Industrial automation systems: Provides stable power for PLCs, sensors, actuators with flexible voltage configurations

3 Test and measurement instruments: Delivers precise, adjustable power for lab testing devices

4 Communication systems: Supports base stations, routers, switches with reliable power supply and current sharing for parallel operation

5 Broadcast and media equipment: Powers video cameras, editing systems, transmitters needing stable and modular power

6 Data center and server applications: Flexible power modules for server racks or edge computing devices

7 Research and development labs: Adjustable voltage/current outputs for prototype testing and experimentation

注意事项 PRECAUTIONS

1 Installation: Blank slots in the chassis must be filled with BLANK-NMS240 accessory to ensure proper operation

2 Temperature derating: When output voltage is below12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of rated value

3 Global ON/OFF control: The shorting connector (from RC1 to GND-P) must be assembled; without it, the power supply will have no output

4 Remote sense: Use +S/-S pins to compensate voltage drop on load wiring (max 0.5V)

5 Current sharing: For parallel operation of NMS-240 modules, connect CS pins together; ensure output voltage difference between modules is <0.2V; total output power should not exceed 1200W (NMP1K2)

6 Over temperature alarm: T-Alarm signal (TTL level) indicates internal temp status; high (4.5~5.5V) means temp exceeds limit, low (0~0.5V) means normal

7 Local ON/OFF control: For NMS-240 modules, short RC2 to GND to turn off output; open to turn on; for NMD-240, use RC2/RC3 pins for V1/V2 control respectively

8 Parallel operation: Max 6 slots for NMP1K2; when load is <10% of rated, some modules may enter standby mode; PC function is not allowed in parallel operation
