产品特点 FEATURES

1 Modular power supply design (NMP1K2 model supports up to 6 slots, 1200W maximum total output power)

2 Complies with medical safety standards (2x MOPP between primary and secondary) and ITE standards, suitable for medical and industrial applications

3 Wide input voltage range: 90~264VAC or 120~370VDC, adaptable to different power grids

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

5 Multiple output module options: Supports single output modules (NMS-240 series) with adjustable voltage ranges (5V,12V,24V,48V) and dual output modules (NMD-240 series)

6 Rich protection functions: Overload protection (constant current limiting or shut down), overvoltage protection (shut down and recover on re-power), overtemperature protection (shut down and auto-recover when cool)

7 Flexible control functions: Global and local ON/OFF control, remote sense to compensate for wiring voltage drop, output voltage/current programming (PV/PC), DC OK signal for output status monitoring, T-Alarm for overtemperature alert

8 Current sharing capability: Allows parallel operation of modules to increase output current (with proper connection and voltage matching)

9 Auxiliary power output: 5V/2A (NMP1K2) for system control and monitoring

注意事项 PRECAUTIONS

1 Installation: Ensure proper mounting torque for terminals (12Kgf-cm for AC input,10Kgf-cm for DC output) to avoid loose connections

2 Global ON/OFF control: Use the correct shorting connector for the global RC1 pin to enable power output; open RC1 (CN32-PIN6) to GND-P (CN32-PIN3) for OFF, short for ON

3 Temperature derating: When output voltage <12V and ambient temperature is -15~-30°C, derate output current to 90% of rated value; follow derating curves for ambient temperature and input voltage

4 Parallel operation: Ensure output voltage difference <0.2V when paralleling modules; do not exceed total output power (1200W for NMP1K2); avoid using PC function in parallel mode

5 Remote sense: Use twisted pairs for sense lines (+S/-S) to minimize noise; connect correctly to compensate for wiring voltage drop

6 Wiring: Use appropriate wire gauge for input/output connections to handle current and reduce voltage drop

7 Safety: Follow electrical safety guidelines during installation/maintenance; disconnect power before servicing

8 Manual reference: Consult official MEAN WELL NMP series manual for detailed parallel/series operation or advanced control functions
