产品特点 FEATURES

1 Modular design with 4 slots (NMP650 series), supporting up to 650W total output power

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

3 Wide input voltage range: AC90~264V or DC120~370V; frequency range:47~63Hz

4 High efficiency up to 91% (full load with H/K modules at 24V/48V) and power factor >0.95 at full load (230VAC)

5 Compliance with multiple safety standards: ANSI/AAMI ES60601-1, UL62368-1, TUV EN60601-1, EN62368-1, IEC60601-1, IEC62368-1, EAC TP TC004

6 Rich functional features: remote sense (compensates up to 0.5V voltage drop), output voltage/current programming (PV/PC pins), global/local ON/OFF control, DC OK signal (module status indication), temperature alarm (T-Alarm), current sharing (parallel modules)

7 Comprehensive protections: overload (constant current limiting), overvoltage (shut down and recover on repower), overtemperature (auto-recover after cooling)

8 Wide working temperature range: -30~+70°C (with derating as per curve)

9 Compact dimensions:250*89*41mm; net weight ~1.45kg

10 Auxiliary power output:5V@1.5A (for NMP650)

使用场景 APPLICATIONS

1 Industrial automation systems requiring multiple stable DC power outputs

2 Medical equipment (compliant with medical safety standards like ES60601-1)

3 Test and measurement instruments needing adjustable and reliable power

4 Communication base stations and network equipment

5 Industrial control systems (PLCs, DCS, etc.)

6 LED display systems and lighting applications

7 Laboratory equipment and R&D setups

8 Any application where modular, flexible, and efficient power supply is needed

注意事项 PRECAUTIONS

1 Derate output current as per curve: reduce to 90% when output voltage <12V and ambient temp is -15~-30°C; derate at temps above 50°C as specified

2 Proper mounting: use M4 screws with torque7~10 Kgf-cm; follow airflow direction for heat dissipation

3 Global ON/OFF control: assemble shorting connector (RC1 to GND-P) if not using external control; use dry contact between RC1 and GND-P otherwise

4 Remote sense lines should be twisted pairs to minimize interference

5 Parallel modules for current sharing: connect CS pins; ensure voltage difference <0.2V; total power ≤650W; do not use PC function; turn ON/OFF all modules simultaneously

6 Avoid condensing humidity environments (20~90% RH non-condensing)

7 Do not overload beyond 650W max capacity

8 Local ON/OFF control: use dry contact between RC2 (NMS-240) or RC2/RC3 (NMD-240) and corresponding GND pins

9 Handle overtemperature alarms promptly: check cooling if T-Alarm signal is high

10 Use compatible accessories (blank slots for unused positions) as recommended
