- AC Input Power Socket: Connects to the main power supply.
- Fuse Box: Contains the protective fuse.
6. Setup
- Unpacking: Carefully remove the power supply and all accessories from the packaging.
- Input Voltage Selection: Before connecting the power cord, ensure the AC input voltage switch on the rear panel is set to match your local mains voltage (230V or 115V). Incorrect selection can damage the unit.
- Power Connection: Connect the provided power cord to the AC input power socket on the rear panel and then to a suitable wall outlet.
- Output Connections: Connect the test lines to the output terminals (red to positive, black to negative, green to ground if needed) and then to your load device. Ensure connections are secure.
7. Operating Instructions
7.1 Powering On/Off
- Press the Power Switch on the front panel to turn the unit ON or OFF.
7.2 Adjusting Voltage and Current
The power supply uses an encoder knob for precise adjustment.
- Press the V/A (Voltage/Current Switching) button to select whether you want to adjust voltage or current. The corresponding digit on the display will blink.
- Rotate the Encoder Knob to increase or decrease the numerical value. Clockwise rotation increases the value, counter-clockwise decreases it.
- Press the Encoder Knob to move the cursor to the desired digit position for fine adjustment.
7.3 Output Control
- Press the Output button to enable or disable the power output. The 'OUT' indicator light will show the status.
- System Settings: Long press the Output button for 5 seconds to enter the system settings menu. Here you can adjust LCD screen brightness and eliminate key tones.
7.4 Over Current Protection (OCP) Mode
- To enter OCP mode, long press the Current adjustment knob (or the dedicated OCP button on some models).
- When a short circuit occurs in the output, the machine will stop outputting and provide an alarm prompt, and the OCP indicator light will illuminate.
7.5 USB Fast Charging Interface
Some models are equipped with USB-A and/or USB-C fast charging ports for convenient device charging.
7.6 Data Storage Function (M1, M2, M3)
Certain models feature three sets of data storage buttons (M1, M2, M3) to quickly recall frequently used voltage and current settings.
- To save a setting: Adjust the desired voltage and current, then long press one of the M1, M2, or M3 buttons until the display confirms saving.
- To recall a setting: Short press the corresponding M1, M2, or M3 button to load the saved values.
8. Maintenance
- Cleaning: Disconnect the power supply from the mains before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents.
- Ventilation: Ensure the cooling fan and ventilation openings on the sides and rear are free from dust and obstructions. Regularly clean the fan area to maintain optimal cooling.
- Fuse Replacement: If the unit does not power on, check the fuse located in the fuse box on the rear panel. Replace it with a fuse of the same type and rating if blown.
- Storage: Store the power supply in a cool, dry place away from direct sunlight and extreme temperatures when not in use for extended periods.
9. Troubleshooting
| Problem | Possible Cause | Solution |
