Applying Voltage to the Load
- Press the Off/On key on the front panel to apply the voltage to the load. The “Output” and “C.V.” indicators on the display light. The power supply works in constant voltage (CV) mode; the display now shows the actual output voltage and current.
If the current exceeds the set current limit, the power supply automatically goes into constant current (CC) mode. The “C.V.” indicator goes out and the “C.C.” indicator on the display lights
- Press the Off/On key to switch the output off.
Setting Voltage and Current
You can save 3 different voltage/current settings using the memory keys M1~M3.
- Press the “V/A” key on the front panel to set the voltage. The voltage readout flashes.
For use in constant voltage mode: this is the desired constant voltage.
- Turn the round adjustment knob until you reach approximately the desired voltage. Press the adjustment knob to select a digit in the voltage readout and turn the adjustment knob to fine-tune.
- Press the “V/A” key again to set the current. The current readout flashes.
- For use in constant voltage mode: this is the desired current limit.
- For use in constant current mode: this is the desired constant current.
- If you enable overcurrent protection, the output switches off automatically if the current exceeds this value.
- Turn the round adjustment knob until you reach approximately the desired current. Press the adjustment knob to select a digit in the current readout and turn the adjustment knob to fine-tune.
- Press the memory key “MEN” again (or wait until the display to start flashing). Then press the M1-M3 button The settings are saved in the selected memory (the display stops flashing).
Recalling Settings
To recall one of the saved settings, press the corresponding memory key M1~M3, the corresponding voltage/current settings appear on the display.
Note: the output is switched off automatically when you press a memory key to recall a setup.
Using the Power Supply in Constant Current Mode
If you want to use the power supply in constant current mode: you set up the desired output current between 0A and 3A/5A. You also set up the desired voltage limit.
Using the Power Supply in Constant Voltage Mode
If you want to use the power supply in constant voltage mode, you set up the desired output voltage between 0V and 30V. You also set up the desired current limit.
If the output current exceeds the limit, the power supply automatically goes into constant current mode.
Switching the Power Supply On or Off
- Connect the included power cord to the back of the device (see the pic. below) and plug the other end into a suitable, earthed power socket. Always connect the device to an earthed power socket!
- Press the Power button on the front panel to switch the power supply on. At this moment, there is no output voltage or current on the output terminals.
- Press the Power button to switch the power supply off.
Connecting a Load
- Connect the load’s positive terminal to the red terminal “+” of the power supply.
- Connect the load’s negative terminal to the black terminal “-” of the power supply.
- You can connect “+” or “-“ terminal to the green earth terminal of the power supply to pin the voltage to 0V (earth potential) at that terminal.
If you leave the earth terminal unconnected, the output floats with respect to the ground.
WEB Access and Network Settings

Remote control mode allows you to operate a power supply via WEB interface using your preferred Internet browser.
