产品特点 FEATURES

Modular power supply system (NMP1K2 model) with up to 6 slots for output modules

1 Supports single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240:30V/5A x2) modules

2 Wide input voltage range: AC 90~264V or DC120~370VDC

3 High efficiency up to 91% (full load with 24V/48V modules)

4 Complies with safety standards: IEC/UL62368-1, IEC60601-1 (2x MOPP isolation for medical applications)

5 Built-in protection: Overload (constant current limiting), overvoltage (shutdown & re-power recovery), overtemperature (shutdown & auto-recovery)

6 Advanced functions: Remote sense (compensates up to 0.5V voltage drop), output voltage/current programming, DC OK signal (TTL level), current sharing for parallel operation

7 Global and local ON/OFF control options

8 Operating temperature range: -30°C ~ +70°C (with derating)

9 Compact front-end dimensions: 250x127x41mm

10 Auxiliary power outputs: +5V/2A (front-end) and +5V/10mA (per module)

使用场景 APPLICATIONS

Industrial automation systems (PLCs, DCS, motor drives)

1 Medical equipment (compliant with IEC60601-1)

2 Test and measurement instruments

3 Telecommunication and data communication systems

4 LED lighting control systems

5 Industrial control panels

6 Server and data center power distribution

7 Audio/visual equipment racks

8 Renewable energy systems (DC input applications)

注意事项 PRECAUTIONS

Must install the shorting connector (RC1 to GND-P) to activate the output

1 Ensure proper airflow direction (as per mechanical specs) for heat dissipation

2 When using remote sense, use twisted-pair cables for +S/-S pins to reduce noise

3 For parallel operation: Connect CS pins of modules, ensure output voltage difference <0.2V between modules, total load not exceeding 1200W

4 Follow derating curves: Reduce load at ambient temps above 50°C or input voltages below 115VAC

5 Local ON/OFF control: For NMS-240 modules, open RC2 to GND for ON, short for OFF; for NMD-240 modules, use RC2 (V1) and RC3 (V2) respectively

6 Do not exceed auxiliary power limits: +5V-AUX-P (2A max for NMP1K2), Vcc2 (10mA max per module)

7 Use appropriate wiring: Control pins (20-26AWG), output terminals (M3.5 screws with max torque 10Kgf-cm)

8 If T-Alarm signal is triggered (high level), check ventilation or reduce load to prevent overheating

9 When output voltage <12V and temp between -15°C and -30°C, derate output current to 90% of rated value
