产品特点 FEATURES

1 Modular structure with 6 slots, supporting flexible configuration of single-output (NMS-240 series:5V/36A,12V/20A,24V/10A,48V/5A) and dual-output (NMD-240 series:30V/5A dual) power modules

2 1200W maximum total output power to meet high-power application needs

3 Wide input voltage range: AC90~264V or DC120~370VDC, adaptable to global power grids

4 Multiple protection mechanisms: Over-temperature protection (OTP), overload protection (OLP), over-voltage protection (OVP), and constant current limiting

5 Rich control and monitoring functions: Remote sense (compensates for load wiring voltage drop up to 0.5V), current sharing (for parallel module operation), DC OK signal (TTL level indicating output status), and local/global ON/OFF control

6 High energy efficiency: Up to 91% typical efficiency, reducing energy consumption and heat generation

7 Strict safety compliance: Conforms to IEC60601-1 (medical equipment) and IEC62368-1 (ITE equipment) standards, with 2x MOPP isolation between primary and secondary circuits

8 Stable output performance: Low ripple and noise, excellent line regulation and load regulation

使用场景 APPLICATIONS

1 Medical equipment: Suitable for devices requiring high safety and stability, such as diagnostic instruments, monitoring equipment, and treatment devices

2 Industrial automation: Power supply for PLC systems, servo drives, sensors, and control panels in factory automation lines

3 Test and measurement: Provides reliable power for electronic test equipment like oscilloscopes, signal generators, and load testers

4 Communication systems: Supports base stations, routers, switches, and other network equipment

5 Data centers: Modular power supply for server racks and storage systems

6 LED lighting: High-power LED display screens, street lighting, and industrial lighting systems

7 Other high-power applications: Laboratory equipment, audio-visual systems, and renewable energy systems

注意事项 PRECAUTIONS

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

2 Parallel operation guidelines: Ensure output voltage difference between modules is less than 0.2V; total output power should not exceed 1200W; use short and thick wires for parallel connections; remote control must simultaneously turn on/off all parallel modules; do not use the output current programming (PC) function in parallel mode

3 ON/OFF control: If global ON/OFF control is not used, assemble the provided shorting connector (RC1 to GND-P); for local control, open RC2/GND to turn on the module, short to turn off

4 Installation precautions: Use M4 screws with a mounting torque of 7~10Kgf-cm; ensure sufficient airflow for heat dissipation to avoid overheating

5 Wiring specifications: Use 20~26AWG wires with a strip length of 10mm for output terminals; twist remote sense lines to reduce interference

6 Environmental adaptation: Refer to the derating curve for adjustments under high ambient temperatures or low input voltage conditions

7 Maintenance: Regularly check for loose connections, dust accumulation, and abnormal heat generation to ensure long-term stable operation
