产品特点 FEATURES

1 Modular power supply with 6 slots (NMP1K2 model), supporting up to 1200W total output power.

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

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

4 Safety compliance: Meets medical (2x MOPP between primary-secondary) and ITE standards (EN60601-1 Ed3.1, UL62368-1, etc.), earth leakage current <400uA@264VAC, touch current <100uA@264VAC.

5 Protection mechanisms: Overload (constant current limiting), overvoltage (shut down, re-power to recover), over-temperature (auto recover when cooled), short circuit (hiccup or constant current limiting).

6 Flexible functionality: Remote on/off (global and local), remote sense (compensates up to 0.5V wiring drop), voltage/current programming (PV/PC pins), DC OK signal (TTL level), current sharing for parallel modules.

7 Auxiliary power outputs: 5V-AUX-P (2A for NMP1K2) for front-end, Vcc2 (5V/10mA) for output modules.

8 Mechanical specs: Dimensions 250x127x41mm (LxWxH), M4 mounting screws (torque7-10 Kgf-cm), specified air flow direction.

注意事项 PRECAUTIONS

1 Installation: Use M4 screws with torque7-10 Kgf-cm; follow specified air flow direction to ensure proper cooling.

2 Wiring: Use adequate wire gauge to minimize voltage drop; twist remote sense lines (+S/-S) to reduce electromagnetic interference.

3 Derating: Follow derating curves (e.g., output voltage <12V and temp -15~-30°C: derate to90% of rated current; ambient temp above50°C: adjust output power as per curve).

4 Parallel operation: Connect CS pins of modules; ensure output voltage difference <0.2V among parallel modules; total power not exceed1200W (NMP1K2).

5 Remote control: Install shorting connector (RC1 to GND-P) if global on/off is not used; local on/off: open=ON, short=OFF (RC2/RC3 pins to GND).

6 Safety: Disconnect AC power before maintenance; adhere to application-specific safety standards (medical/ITE).

7 Programming: Use PV/PC pins within specified voltage ranges; reference to GND when using these functions.
