产品特点 FEATURES

1 Brand: MW (Meanwell), Model: NMP1K2-HKHHHH-12 (part of NMP series modular power supplies)

2 Modular design: 1200W maximum total power with 6 slots, supports interchangeable single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240: up to 30V per channel,240W total per module) modules

3 Wide input range:90~264VAC or120~370VDC,47~63Hz frequency compatibility

4 High efficiency: Up to91% typical at full load with H/K modules (24V/48V nominal)

5 Comprehensive safety compliance: Meets medical (2x MOPP isolation between primary-secondary) and ITE standards including ANSI/AAMI ES60601-1 Ed3.1,UL62368-1,TUV EN60601-1 Ed3.1,EN62368-1,IEC60601-1 Ed3.1,IEC62368-1

6 Multiple protection mechanisms: Overload (constant current limiting), overvoltage (shut down output, repower to recover), overtemperature (auto-recover after cooling), short circuit (hiccup mode or constant current limiting)

7 Flexible control functions: Global/local remote on/off, remote sense (compensate up to0.5V wiring drop), output voltage programming (PV pin), output current programming (PC pin), DC OK signal (TTL level indicating module status), current sharing (for parallel operation)

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

9 Mechanical specifications: NMP1K2 front-end dimensions250×127×41mm (L×W×H), weight~2kg; module dimensions118.5×37.9×18mm

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices, patient monitors, and treatment equipment requiring medical-grade isolation and stable power

2 Industrial automation: PLC systems, control panels, and robotic equipment needing multiple customizable voltage outputs

3 Test & measurement instruments: Lab equipment and calibration tools requiring precise voltage/current adjustment and programmable settings

4 Telecom & data centers: Base stations, server racks, and network devices needing high-efficiency, modular power solutions with parallel operation capability

5 Laboratory research: Custom experimental setups requiring flexible voltage configurations and remote monitoring/control

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding; use M4 screws for front-end mounting with torque7~10Kgf-cm; fill blank slots with BLANK-NMS240 modules to maintain safety and airflow

2 Operation: Install the provided shorting connector (RC1 to GND-P) if not using global remote on/off; use twisted pairs for remote sense lines to minimize interference

3 Derating requirements: When output voltage <12V and ambient temperature is -15~-30°C, derate output current to90% of rated value; follow derating curves for ambient temperature and input voltage to avoid overheating

4 Parallel operation: For current sharing, connect CS pins of all modules; ensure output voltage difference between parallel modules <0.2V; total load must not exceed1200W for NMP1K2; do not use current programming (PC) function in parallel mode

5 Protection handling: In case of overvoltage/overtemperature shutdown, power off the device, check load and environment, then repower after cooling; for overload, reduce load to within rated limits

6 Environmental: Avoid operating in condensing humidity; keep ambient temperature within -30~+70°C (with derating above50°C)
