产品特点 FEATURES

1 Modular power supply design: NMP1K2 model supports up to 6 slots (1200W maximum total power), compatible with single-output (NMS-240, up to 240W per module) and dual-output (NMD-240, up to 240W combined) modules

2 Wide input voltage range: 90~264VAC or 120~370VDC, frequency range 47~63Hz, suitable for global applications

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

4 Comprehensive protection: Over-temperature (OTP), over-voltage (OVP), over-current (OCP), overload (OLP) protections; auto-recovery after fault removal for some protections

5 Flexible control functions: Global/local ON/OFF control, remote sense (compensates up to 0.5V voltage drop), output voltage (PV) and current (PC) programming, DC OK signal (TTL level), current sharing (CS) for parallel operation

6 Safety compliance: Meets medical (2x MOPP between primary and secondary) and ITE standards; earth leakage current <400uA/264VAC, touch current <100uA/264VAC

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

8 Compact mechanical design: Front-end dimensions 250×127×41mm (L×W×H), modules 118.5×37.9×18mm (L×W×H)

使用场景 APPLICATIONS

1 Industrial automation: Powering PLCs, sensors, actuators, and other control equipment

2 Medical devices: Suitable for low-risk medical equipment (e.g., diagnostic tools, patient monitoring devices) due to medical safety compliance

3 Telecommunications: Providing stable power for routers, switches, base stations, and communication cabinets

4 Test and measurement: Supporting lab instruments that require adjustable voltage/current outputs

5 Data centers: Modular power solution for server racks or network equipment

6 Custom electronic systems: Ideal for applications needing flexible power configurations (different voltage/current combinations)

7 Industrial equipment: Powering machinery, robotics, and process control systems

注意事项 PRECAUTIONS

1 Installation: Use recommended screw sizes (M4 for front-end, M3.5 for modules) and torque limits (max 12Kgf-cm for front-end, max10Kgf-cm for modules) to avoid damage

2 Temperature derating: Follow derating curves for ambient temperatures; for output voltage <12V and ambient -15~-30°C, reduce output current to 90% of rated value

3 Parallel operation: When paralleling NMS-240 modules, connect CS pins, ensure output voltage difference <0.2V, total power ≤1200W (NMP1K2), use short/large-diameter wires, and remote control must turn all modules on/off simultaneously

4 Remote control setup: For NMS-240 local ON/OFF, open RC2 (pin3) to GND for ON, short for OFF; for NMD-240, open RC2/RC3 to respective GNDs for ON

5 Accessory use: Install the provided shorting connector (RC1 to GND-P) to enable output; contact Meanwell for parallel/series connection accessories

6 Safety: Ensure proper grounding; do not exceed maximum load limits for individual modules or total system

7 Fault handling: For over-temperature protection, wait for the device to cool down before re-powering; for other faults, check load and connections before restarting

8 Storage: Store in a dry, cool environment (-40~85°C, 10~95% RH non-condensing) when not in use
