产品特点 FEATURES

1 Modular design: NMP1K2 model supports up to 6 slots, each compatible with NMS-240 single-output modules (5V/36A,12V/20A,24V/10A,48V/5A) or NMD-240 dual-output modules, max total power 1200W

2 Wide input range: AC 90-264V, DC120-370VDC; frequency range 47-63Hz

3 High efficiency and power factor: Up to 91% typical efficiency (full load with H/K modules at 24V/48V); PF>0.95 at full load (230VAC), PF>0.98 at full load (115VAC)

4 Rich control functions: Global/local ON/OFF control (via RC1/RC2 pins), 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), over-temperature alarm (T-Alarm signal)

5 Multiple protection mechanisms: Overload (constant current limiting), overvoltage (shut down and recover on re-power), overtemperature (shut down and auto-recover when cool)

6 Safety compliance: Meets IEC60601-1 (medical,2x MOPP), IEC62368-1, UL62368-1, TUV EN60601-1 standards; earth leakage current <400uA (264VAC), touch current <100uA (264VAC)

7 Auxiliary power outputs:5V-AUX-P (2A for NMP1K2) for system use; Vcc2 (5V/10mA) for module control

8 Mechanical specs: Dimensions 250×127×41mm (L×W×H); mounting torque guidelines (12Kgf-cm for input terminals,10Kgf-cm for output); airflow direction as per mechanical diagram

9 Derating support: Adjust output current based on ambient temperature and input voltage (e.g., output voltage <12V and temp -15~-30°C: derate to90% rated current)

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding (FG pin connection); follow mounting torque guidelines (12Kgf-cm for input terminals,10Kgf-cm for output); maintain adequate airflow as per direction; use M4 screws for mounting with max penetration depth4mm

2 Operation: Do not exceed max total power (1200W for NMP1K2); follow derating curves for low ambient temperatures (<-15°C) or high load conditions; ensure output voltage difference <0.2V when parallelizing modules; do not use PC function during parallel operation; connect RC1 to GND-P with provided shorting connector if global ON/OFF is not used

3 Safety: Avoid touching live parts when powered on; use cables with appropriate current ratings; comply with local electrical safety regulations; do not disassemble or modify the unit

4 Maintenance: Keep vents clean to prevent overheating; regularly check for abnormal noise or temperature; replace modules only with original MW parts; disconnect power before any maintenance

5 Special notes: When using remote sense, twist +S/-S lines to reduce interference; for NMD-240 dual-output modules, ensure correct wiring for V1/V2 ON/OFF control; do not mix different module types in parallel operation without manufacturer approval
