产品特点 FEATURES

1 Modular design with 6 slots, supporting up to 1200W total output power

2 Compatible with single-output (NMS-240:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240: up to30V/5A each, combined240W) modules

3 Wide input range:90-264VAC or120-370VDC; frequency range47-63Hz

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

5 Complies with multiple safety standards: medical (ANSI/AAMI ES60601-1 Ed3.1, TUV EN60601-1 Ed3.1), ITE (UL62368-1, EN62368-1, IEC62368-1, IEC60950-1), and EAC TP TC004

6 Comprehensive protection: overload (constant current limiting), overvoltage (shutdown, repower to recover), over-temperature (shutdown, auto recover when cooled)

7 Rich functional features: remote sense (compensate wiring voltage drop up to0.5V), output voltage/current programming (PV/PC), DC OK signal (TTL level indicating module status), T-alarm (overtemp signal), current sharing (for parallel operation), global/local ON/OFF control

8 Auxiliary power outputs: front-end5V/2A, module-level5V/10mA

使用场景 APPLICATIONS

1 Industrial automation systems requiring multiple stable DC voltage supplies

2 Medical devices adhering to ES60601-1 safety standards (e.g., diagnostic equipment, patient monitors)

3 Test and measurement setups needing adjustable voltage/current for component testing

4 Telecommunication infrastructure (routers, switches) needing modular and scalable power

5 Data centers/server racks using parallel operation for higher current capacity

6 Embedded system development with varying power requirements (switching modules as needed)

注意事项 PRECAUTIONS

1 Global ON/OFF control: If not using external control, assemble the provided shorting connector (RC1 to GND-P); otherwise, the unit will have no output

2 Remote sense: Use twisted-pair cables for +S/-S lines to reduce electromagnetic interference

3 Voltage/current programming: Follow spec guidelines for PV/PC voltage ranges and ensure correct connections to avoid damage

4 Parallel operation guidelines:

a. Connect CS pins of all modules in parallel to balance current

b. Ensure output voltage difference between modules is <0.2V

c. Total output current ≤ (rated current per module) × number of modules; total power ≤1200W

d. Max6 modules can be paralleled for NMP1K2

e. Use short, thick wires for parallel connections to minimize voltage drop

f. Do not use the PC (current programming) function when modules are in parallel

1 Over-temperature handling: If the unit shuts down due to overheating, allow it to cool to ambient temp before restarting

2 Low-temperature derating: For modules with output voltage <12V and ambient temp between -15°C and -30°C, derate output current to90% of rated value

3 Mounting: Use M4 screws with torque7-10 Kgf-cm to ensure secure installation and avoid mechanical failure

4 Local ON/OFF control: For NMS modules, open RC2 (pin3) to turn on, short to turn off; for NMD modules, open RC2/RC3 to turn on respective outputs
