OPERATION

Connection and Operation Procedure

1.  After checking with the rating label plug in to AC mains.

2.  Switch on the power supply and the LCD display should illuminate

3.  The (CV) icon should be shown on the display.

4.  Turn to current control to maximum if you do not require lower current limiting value, 

otherwise do the preset the (CC) limiting procedure.

5.  Set your desired output voltage and then turn off the output.

6.  Connect to your load positive to positive and negative to negative.

7.  Turn on the output terminal again and check if display shows (CV).

Note

 If display shows (CC), either your preset current limiting value is too low or your 

load requires more voltage and current. Increase the voltage or current accordingly until 

(CV) appears. 

 

Ground Connection 

• 

Depending on the application, the power supply output terminals can be grounded 

in any one of the following grounding conditions : 

• 

Negative ground –  black (-) negative terminal is shorted with green GND terminal.  

Positive ground – red (+) positive terminal is shorted with green GND terminal.  

Floating ground – green terminal is not shorted with any of the output terminals. 

Notes

• 

When operating this power supply as a floating ground, high impedance leakage 

can exist between the power supply circuitry and the chassis ground.
