产品特点 FEATURES

1 Brand: MW (Meanwell), model: NMP1K2-KCCCHK-02, part of NMP series modular power supplies

2 Front-end configuration: 1200W maximum power with 6 slots for output modules

3 Input parameters: AC input 90~264VAC (47~63Hz) or DC input 120~370VDC; power factor >0.95@230VAC full load, >0.98@115VAC full load; typical efficiency up to ~91% at full load with H/K modules (24V/48V)

4 Safety compliance: Meets medical safety standards (2x MOPP isolation between primary and secondary) and ITE standards (e.g., ANSI/AAMI ES60601-1 Ed.3.1, UL62368-1, TUV EN60601-1 Ed.3.1)

5 Output module support: Compatible with single-output modules (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A, each up to240W) and dual-output modules (NMD-240: dual30V@5A, total240W) with adjustable voltage ranges

6 Protection mechanisms: Overload protection (constant current limiting or shutdown), overvoltage protection (shutdown, recover via re-power), overtemperature protection (shutdown, auto-recover after cooling)

7 Functional capabilities: Remote sense (compensates up to0.5V voltage drop), global/local remote ON/OFF control, DC OK signal (TTL level indicating module status), current sharing (parallel module operation), output voltage/current programming (PV/PC pins)

8 Auxiliary power: Front-end provides5V@2A auxiliary output; modules offer5V@10mA auxiliary output

9 Mechanical specs: Front-end dimensions(250×127×41mm L×W×H), module dimensions(118.5×37.9×18mm L×W×H); front-end mounting uses M4 screws with7~10 Kgf-cm torque

10 EMC performance: Complies with EN55032/EN55011 (emission class B), EN61000-4 series (immunity), SEMI F47 standards

使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs, servo drives, sensors, actuators in manufacturing lines

2 Medical equipment: Diagnostic instruments, patient monitors, lab devices requiring medical safety isolation

3 Telecommunications infrastructure: Routers, switches, base station components with multi-voltage needs

4 Test and measurement instruments: Oscilloscopes, signal generators, lab testing setups needing adjustable stable power

5 Data centers: Server racks, storage systems, network devices with modular voltage configurations

6 LED lighting systems: High-power LED arrays, streetlights, indoor lighting installations

7 Broadcast/media equipment: Cameras, mixers, transmitters, editing systems in studio environments

注意事项 PRECAUTIONS

1 Mounting: Use M4 screws with7~10 Kgf-cm torque for front-end; ensure proper airflow direction

2 Parallel operation: For NMS-240 modules, connect CS pins together, voltage difference<0.2V, max6 modules/front-end; total current≤rated per module×count, total power≤1200W; use short/large wires, avoid PC function in parallel

3 Temperature derating: When output voltage<12V and temp-15~-30°C, derate current to90% of rated; reduce load at temps above50°C per derating curves

4 Remote control: Assemble shorting connector (RC1 to GND-P) if not using external global ON/OFF; local ON/OFF via RC2(NMS-240) or RC2/RC3(NMD-240)

5 Safety: Proper grounding to limit leakage current(<400uA@264VAC); use circuit breakers for inrush current(40A@230VAC,25A@115VAC)

6 Programming: Follow PV(voltage)/PC(current) pin guidelines (referenced to module GND); no PC function in parallel

7 Signal handling: Twisted pairs for remote sense lines (+S/-S) to minimize noise; DC OK(4.5~5.5V when on) and T-Alarm(high when overtemp) for status monitoring

8 Fault recovery: Overvoltage shutdown→re-power unit; overtemperature shutdown→wait for cooling before restarting
