产品特点 FEATURES

1 Brand: MW (Meanwell), Model: NMP1K2-HKKKKK-14, belonging to the NMP series of 1200W modular power supplies with 6 slots

2 Input specifications: AC 90-264V, DC 120-370V; frequency range 47-63Hz; power factor >0.95@230VAC full load

3 Efficiency: Up to 91% at full load with H/K modules (24V/48V nominal voltage)

4 Safety certifications: Complies with ITE standards (UL62368-1, EN62368-1, IEC62368-1) and medical standards (ANSI/AAMI ES60601-1 Ed3.1, TUV EN60601-1 Ed3.1, IEC60601-1 Ed3.1) with 2x MOPP isolation between primary and secondary

5 Modular output options: Each slot supports NMS-240 (single output:5V/36A,12V/20A,24V/10A,48V/5A) or NMD-240 (dual output: up to30V@5A each, combined 240W max per module)

6 Protection functions: Overload (constant current limiting), overvoltage (shutdown, repower to recover), over-temperature (shutdown, auto recover when cool), short circuit (hiccup or constant current limiting)

7 Advanced functions: Remote sense (compensates up to0.5V wiring drop), remote ON/OFF (global and local control), DC OK signal (TTL level indicating output status), auxiliary power (5V/2A for NMP1K2), current sharing (for parallel modules), voltage/current programming (via PV/PC pins)

8 EMC compliance: EN55032 Class B (emission), EN61000-4 series (immunity), SEMI F47

使用场景 APPLICATIONS

1 Medical equipment: Diagnostic devices (ultrasound, blood analyzers), patient monitoring systems (benefits from medical isolation and stable power)

2 Industrial automation: PLCs, DCS systems, robotics (modular design allows flexible power allocation)

3 Test and measurement: Lab equipment, signal generators, oscilloscopes (precise voltage/current control via PV/PC pins)

4 Telecommunications: Base stations, network switches (reliable power with redundancy via parallel modules)

5 Data centers: Server racks, storage systems (modular design adapts to varying power needs)

6 Other applications: Scenarios requiring stable, modular power with medical or ITE compliance

注意事项 PRECAUTIONS

1 Installation: Use recommended screws (M4 for front-end, M3.5 for DC output terminals) with specified torque (12Kgf-cm for AC input,10Kgf-cm for DC output); ensure proper grounding

2 Temperature derating: For output voltage <12V and ambient temp between -15°C to -30°C, derate output current to90% of rated; follow derating curves for higher temperatures

3 Global ON/OFF: The shorting connector (RC1 to GND-P) must be installed; otherwise, no output

4 Parallel operation: Connect CS pins together; ensure output voltage difference <0.2V; total power ≤1200W; do not use PC function in parallel

5 Remote sense: Use twisted pairs for sense lines to minimize noise

6 Over-temperature: If T-Alarm signal is high (4.5-5.5V), improve airflow or reduce load

7 Wiring: Use appropriate wire gauge for input/output to minimize voltage drop
