产品特点 FEATURES

1 Modular power supply (model NMP1K2-EEEEHC-02) from MW (Meanwell), featuring 6 slots for output modules (each up to 240W, e.g., NMS-240 single output or NMD-240 dual output)

2 Wide input range: 90~264VAC / 120~370VDC, frequency 47~63Hz; high power factor (PF>0.95@230VAC full load, PF>0.98@115VAC full load)

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

4 Compliance with medical and ITE safety standards: ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1, EN62368-1, IEC60601-1 Ed3.1, IEC62368-1, TUV IEC60950-1, EAC TP TC004; 2x MOPP isolation between primary and secondary

5 Comprehensive protection: Overload (constant current limiting), overvoltage (shut down, re-power to recover), overtemperature (shut down, auto recover when cool), inrush current limiting, leakage current <400uA@264VAC

6 Flexible control functions: Global ON/OFF (RC1 pin), local ON/OFF (RC2/RC3 pins), remote sense (compensates up to 0.5V voltage drop), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (TTL level, 4.5~5.5V when ON), current sharing (CS pin for parallel operation)

7 Auxiliary power: 5V/2A from front-end (NMP1K2), 5V/10mA per output module

8 Mechanical specs: Dimensions 250x127x41mm (LxWxH), weight ~2kg; mounting with M4 screws (torque 7~10Kgf-cm)

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and control systems requiring stable, modular power

2 Medical equipment: Suitable for devices compliant with medical safety standards (2x MOPP isolation)

3 Telecom infrastructure: Flexible power distribution in rack-mounted systems for routers, switches, and communication devices

4 Test and measurement: Stable output with low ripple/noise (100~250mVp-p max) for precision instruments

5 Data centers: Parallel operation of modules for high reliability and scalable power capacity

6 Laboratory setups: Adjustable voltage/current (via PV/PC pins) for various experimental and testing needs

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding; use M4 screws for mounting with torque 7~10Kgf-cm; keep vents clear for airflow

2 Global ON/OFF control: If not using global control, short RC1 (CN32-PIN6) to GND-P (CN32-PIN3) with the provided shorting connector

3 Local ON/OFF control: For NMS-240 modules, open RC2 (PIN3) to GND (PIN1/2) for ON, short for OFF; for NMD-240 modules, open RC2 (PIN3) to GND1 (PIN1) for V1 ON, open RC3 (PIN4) to GND2 (PIN2) for V2 ON

4 Remote sense: Connect +S/-S pins to load terminals to compensate for voltage drop (max 0.5V)

5 Parallel operation (NMS-240 only): Connect CS pins of all modules; ensure output voltage difference <0.2V between modules; total power ≤1200W; use short/large-diameter wires; remote control must turn all modules ON/OFF simultaneously; do not use PC function in parallel

6 Derating: For output voltage <12V and ambient temperature -15~-30°C, derate current to 90% of rated; refer to derating curves for high-temperature operation

7 Safety: Do not operate beyond specified voltage/current limits; avoid touching live parts when powered; disconnect power before maintenance

8 Maintenance: Regularly check for overheating (T-Alarm signal indicates temp limit exceeded); keep the unit clean and free of dust
