Product Description

 

1. Adopting no low frequency transformer switching power supply technology, so it has AC and DC compatible input function, also the input voltage range is wide.

 

2. Adopting the advanced switching power supply control technology, components & partsand elaborate design.

 

3. Many units can be parallel operated to enlarge current, and it has automatic current sharing function.

 

4. It can provide 2 (0-5V) analogue signals to adjusting the output constant voltage value and constant current value; it can provide 5V level signal input port to control unit turn on and off; it can provide function of sampling outside of positive and negative pole to reduce the voltage drop on the wire.

 

5. It has the features of small volume, light weight, high efficiency, which ensures the stability and credibility of long-term full-load operation.

 

6. Output voltage and current are respectively and individually digital displayed.

 

7. Output constant voltage value and constant current value can be continuously adjusted within the range of respective maximum value (0-100%).
