产品特点 FEATURES

1 Modular power supply design: NMP1K2 model offers 6 slots for output modules, supporting up to 1200W total power

2 Wide input range: AC 90~264V, DC120~370VDC; frequency range 47~63Hz

3 High efficiency: Up to 91% (for H/K modules at 24V/48V full load)

4 Multiple output module options: Single output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual output (NMD-240: up to 30V@5A each, combined 240W)

5 Comprehensive protection functions: Overload (shut down, repower to recover), overvoltage (constant current limiting), overtemperature (auto shut down and recover when cooled)

6 Rich control features: Remote ON/OFF (global and local), current sharing (for parallel operation), remote sense (compensate wiring voltage drop up to 0.5V), voltage/current programming, DC OK signal (TTL level), over-temperature alarm signal (TTL level)

7 High safety compliance: Meets medical (2x MOPP isolation) and ITE standards (ANSI/AAMI ES60601-1, UL62368-1, EN60601-1, etc.)

8 Strong EMC performance: Complies with EN55032, EN55011, and EN61000 series for emission and immunity

9 Compact size: NMP1K2 front-end is 250×127×41mm; output modules are 118.5×37.9×18mm

10 Auxiliary power output: 5V/2A (NMP1K2) for system use

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring medical safety standards (2x MOPP isolation)

2 Industrial automation systems: Powering PLCs, sensors, actuators with multiple DC voltage needs

3 Test and measurement instruments: Providing stable, adjustable DC outputs for various testing setups

4 Communication systems: Supporting base stations, routers, and other devices needing reliable power

5 Instrumentation: Powering precision instruments with different voltage requirements

6 Parallel operation applications: For higher power demands by connecting multiple modules in parallel (up to 6 slots for NMP1K2)

7 Laboratory setups: Flexible power supply for R&D projects needing configurable outputs

注意事项 PRECAUTIONS

1 Derating requirement: When output voltage <12V and ambient temperature is between -15°C and -30°C, reduce output current to 90% of rated value

2 Mounting: Follow recommended screw sizes (M4 for front-end, M3.5 for modules) and torque (12Kgf-cm for front-end AC terminal,10Kgf-cm for module DC terminal)

3 Global ON/OFF control: Ensure the shorting connector (RC1 to GND-P) is assembled; otherwise, the unit has no output

4 Parallel operation rules: Max 6 slots for NMP1K2; connect CS pins for current balancing; output voltage difference among parallel modules should be <0.2V; total power not exceed1200W; use short, large-diameter wiring

5 Remote sense: Use +S/-S pins to compensate voltage drop on load wiring (up to0.5V)

6 Overtemperature protection: The unit shuts down when overheated and recovers automatically after cooling down

7 Overload/overvoltage handling: Overload triggers shut down (repower to recover); overvoltage uses constant current limiting

8 Local ON/OFF control: For NMS-240 modules, open RC2 to GND for ON, short for OFF; for NMD-240, control V1/V2 separately via RC2/RC3
