使用场景 APPLICATIONS

1 Industrial automation systems: Powering PLCs,sensors,actuators requiring multi-voltage stable power

2 Medical devices: Suitable for patient monitors,diagnostic equipment due to medical safety compliance

3 Test and measurement labs: Flexible voltage/current programming and remote control meet lab setup needs

4 Telecommunication networks: Supporting routers,switches with multiple voltage requirements

5 Data center infrastructure: Parallel operation ensures high reliability for server racks or storage systems

6 LED lighting applications: Remote sense compensates cable voltage drop for stable lighting

7 Precision instrumentation: Adjustable outputs with low ripple noise fit for analytical devices

注意事项 PRECAUTIONS

1 Installation: Ensure the shorting connector(RC1 to GND-P) is assembled;otherwise no output.Use M4 screws for mounting with torque7~10Kgf-cm

2 Operation:

3 Local ON/OFF: For NMS-240,open RC2-GND to turn on;short to turn off.For NMD-240,use RC2/GND1(V1) and RC3/GND2(V2)

4 Remote sense: Connect +S/-S to load terminals to compensate voltage drop(max0.5V)

5 Programming: Use PV pin for voltage adjustment(referenced to GND) and PC pin for current adjustment(referenced to GND)

6 Parallel operation: Connect CS pins of modules;output voltage difference <0.2V;total power ≤650W;avoid PC function in parallel

7 Environmental:

8 Operating temperature: -30~+70℃(derate current if temp>50℃;Vo<12V and -15~-30℃:derate to90% rated current)

9 Humidity:20~90% RH non-condensing;storage temp:-40~+85℃

10 Safety: Disconnect AC/DC input before maintenance;ensure proper grounding

11 Maintenance: Regularly clean dust to prevent overheating;check DC OK and T-Alarm signals for abnormalities
