产品特点 FEATURES

Modular power supply with 1200W maximum output (6 slots) from MW (明纬)

1 Wide input range: 90~264VAC /120~370VDC, 47~63Hz; high power factor (PF>0.95@230VAC full load) and efficiency up to 91% (typical with H/K modules at 24V/48V full load)

2 Safety certifications: Complies with ANSI/AAMI ES60601-1 Ed3.1, UL62368-1, TUV EN60601-1 Ed3.1, EN62368-1, IEC60601-1 Ed3.1, IEC62368-1, EAC TP TC004; isolation levels: Primary-Secondary (2x MOPP), Primary-Earth (1x MOPP); withstand voltage: I/P-O/P (4KVAC), I/P-FG (2KVAC), O/P-FG (0.5KVAC)

3 Rich protection functions: Overload (shut down, re-power to recover), overvoltage (constant current limiting), overtemperature (shut down, auto recover when cool), short circuit (hiccup or constant current limiting based on module type)

4 Flexible control functions: Global/local ON/OFF, remote sense (compensate up to 0.5V line drop), output voltage programming (PV), output current programming (PC), DC OK signal (TTL level), current sharing (for parallel operation), T-alarm (overtemperature signal)

5 Mechanical specs: Dimensions 250×127×41mm (L×W×H), typical weight 2kg; packing:6pcs/13kg/0.88CUFT

使用场景 APPLICATIONS

Medical equipment: Diagnostic devices, patient monitors, and other medical devices requiring 2x MOPP isolation compliance

1 Industrial automation: PLC systems, DCS controllers, servo drives, and factory automation equipment

2 Telecom infrastructure: Base stations, network routers, switches, and communication equipment

3 Test and measurement instruments: Laboratory equipment, signal generators, and power analyzers

4 Other applications: Any system needing flexible, reliable multi-output power with high safety and efficiency standards

注意事项 PRECAUTIONS

Installation:

1 Use recommended screws (M4 for AC input terminals, M3.5 for DC output terminals) with specified torque (12Kgf-cm for AC,10Kgf-cm for DC)

2 Ensure proper grounding to prevent electric shock and reduce noise

Operation:

1 Global ON/OFF control: If not using global control, must install the shorting connector (RC1 to GND-P) to enable output

2 Local ON/OFF control: For NMS-240 modules, short RC2 to GND for OFF, open for ON; for NMD-240 modules, short RC2/RC3 to GND1/GND2 for OFF, open for ON

3 Remote sense: Use twisted-pair cables for +S/-S lines to minimize electromagnetic interference; do not exceed 0.5V compensation limit

4 Parallel operation (NMS-240 modules): Connect CS pins of all modules together; ensure output voltage difference between modules <0.2V; total output current ≤ sum of rated currents of modules; total power ≤1200W; use short, large-diameter wires for parallel connections; remote control must activate all modules simultaneously; do not use output current programming (PC) function when modules are in parallel

5 Derating: Follow derating curves for ambient temperature and input voltage; derate current to90% when output voltage <12V and ambient temp is -15~-30°C

Maintenance:

1 Keep ventilation openings clear to maintain airflow and prevent overheating

2 Avoid operating in environments with condensation, excessive dust, or corrosive gases
