产品特点 FEATURES

1 Modular power supply from MW (Meanwell), model NMP1K2-CHCEHE-00, part of NMP series with 6 slots and max 1200W total power.

2 Supports single-output modules (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output modules (NMD-240:30V/5A each), each module up to 240W.

3 Wide input voltage range:90-264VAC or120-370VDC, frequency47-63Hz; high power factor (>0.95 at230VAC full load).

4 High efficiency up to91% (for H/K modules at nominal24V/48V).

5 Multiple protection functions: Overload (constant current limiting), overvoltage (shutdown, re-power to recover), overtemperature (auto-recover after cooling).

6 Rich control features: Global/local ON/OFF control, remote sense (compensates up to0.5V wiring drop), output voltage/current programming (PV/PC), DC OK signal (TTL level), current sharing (CS for parallel modules).

7 Compliance with safety standards: ITE (UL62368-1) and medical (2x MOPP between primary-secondary) standards; EMC standards like EN55032 (emission) and EN61000 series (immunity).

8 Mechanical specs: Dimensions250×127×41mm, weight~2kg; packing6pcs per carton (13kg).

使用场景 APPLICATIONS

1 Industrial automation: Power for PLCs, servo drives, DCS systems requiring multiple stable DC voltages.

2 Medical equipment: Suitable for low-risk medical devices (diagnostic tools, patient monitors) due to medical safety compliance (2x MOPP).

3 Telecommunications: Base stations, network switches/routers needing modular power solutions.

4 Test & measurement: Lab instruments requiring precise, adjustable DC power outputs.

5 Data centers: Peripheral devices or server racks with diverse voltage needs.

6 LED applications: Large LED displays or industrial lighting systems using different voltage modules.

注意事项 PRECAUTIONS

1 Installation: Ensure proper grounding; use M4 screws for mounting with torque7-10 Kgf-cm (NMP1K2).

2 Temperature derating: Follow derating curves—e.g., output voltage<12V and ambient temp-15°C to-30°C: derate current to90% rated; reduce load at higher temps.

3 ON/OFF control: For global control, assemble shorting connector (RC1 to GND-P) if no external control is used; local module control: open RC2/RC3 for ON, short for OFF.

4 Parallel operation: Connect CS pins of modules; ensure output voltage difference<0.2V; total power≤1200W (NMP1K2); use short/large diameter wires; remote control must act on all parallel modules simultaneously.

5 Remote sense: Use twisted pairs for sense lines to minimize noise; max compensation is0.5V.

6 Over-temperature handling: If T-Alarm signal is high (4.5-5.5V), cool the device immediately to avoid damage.

7 Wiring: Use appropriate wire sizes for terminals; output terminals: M3.5 screws (max10mm penetration, torque≤10 Kgf-cm).
