5. Operating Instructions
5.1 Powering On/Off
Flip the power switch on the rear panel to the ON position. The LED display will illuminate.
5.2 Adjusting Voltage and Current
The power supply features coarse and fine adjustment knobs for precise control:
- V-COARSE / V-FINE: Adjusts the output voltage. Use V-COARSE for large changes and V-FINE for precise adjustments (setting the last two decimal places).
- A-COARSE / A-FINE: Adjusts the output current limit. Use A-COARSE for large changes and A-FINE for precise adjustments.
- Encoder Knob Function: Press the voltage or current knob to switch the number of digits being adjusted. Rotate the knob to set the value.

6. Maintenance
To ensure the longevity and optimal performance of your power supply:
- Keep the unit clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners.
- Ensure the ventilation openings on the sides and rear of the unit are not obstructed to allow proper airflow for the intelligent cooling fan.
- Store the power supply in a dry, cool environment when not in use.
- Regularly inspect the input and output power cords for any signs of damage.
7. Troubleshooting
If you encounter issues with your DC Power Supply, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/display off | Power cord disconnected, power switch off, blown fuse. | Check power cord connection, ensure power switch is ON, inspect and replace fuse if necessary. |
| No output voltage/current | Output terminals not connected, OCP activated, current limit set too low. | Ensure output cords are securely connected. Check if OCP is triggered (alarm/display). Increase current limit using A-COARSE/A-FINE knobs. |
| Inaccurate readings | Loose connections, external interference. | Ensure all connections are secure. Minimize external electromagnetic interference. For precise measurements, use a calibrated multimeter. |
| Unit overheating | Obstructed ventilation, prolonged high load. | Ensure ventilation openings are clear. Reduce load or allow unit to cool down. The intelligent cooling fan should activate. |
If the problem persists, please contact Kungber Technical Support.
