产品特点 FEATURES

1 Modular 6-slot design: 1200W front-end (NMP1K2) compatible with interchangeable single-output modules (NMS-240) supporting 5V (C),12V(E),24V(H),48V(K) (240W max per module)

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

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

4 Safety compliance: Meets medical (2x MOPP isolation) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1)

5 Advanced functional pins: Remote sense (compensates up to 0.5V wiring drop), output voltage programming (PV), output current programming (PC), DC OK signal (TTL level), current sharing (CS for parallel operation)

6 Comprehensive protection: Overload (constant current limiting), overvoltage (shut down, re-power recover), overtemperature (auto-recover when cool), short circuit

7 Auxiliary power: Front-end provides 5V/2A aux power; each module offers 5V/10mA aux power

8 Compact size: 250×127×41mm (L×W×H)

9 Flexible control: Global (RC1 pin) and local (RC2 pin) ON/OFF options

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators with diverse DC voltage needs

2 Medical devices: Compliant with medical safety standards for equipment requiring isolated power

3 Telecommunications: Supporting routers, switches, base stations with multiple voltage outputs

4 Test & measurement: Customizable voltage configurations for lab instruments and testing setups

5 Data centers: Parallel operation of modules for high reliability and load balancing

6 Embedded systems: Tailored power solutions for specialized hardware designs

注意事项 PRECAUTIONS

1 Installation: Use M4 screws with 7-10 Kgf-cm torque for mounting; install the shorting connector (RC1 to GND-P) if not using external global control

2 Operation:

3 Local ON/OFF: Open RC2 (module pin3) to turn on, short to GND to turn off

4 Remote sense: Connect +S/-S pins to load terminals to compensate for voltage drop

5 Parallel operation: Connect CS pins of modules, ensure output voltage difference <0.2V; total load ≤1200W

6 Environmental:

7 Derate to 90% current if output voltage <12V and ambient temp is -15°C to -30°C

8 Operating temp range: -30°C to +70°C (follow derating curve for high temps)

9 Avoid condensing humidity (20-90% RH non-condensing)

10 Safety: Disconnect AC input before maintenance; ground properly via FG terminal to reduce leakage current

11 Maintenance: Do not touch live parts when powered on; replace modules with compatible NMS-240 models only
