5.3 Output ON/OFF Control
- To turn the output ON, press the 'OUT' button. The 'OUT' LED will illuminate.
- To turn the output OFF, press the 'OUT' button again. The 'OUT' LED will turn off.
5.4 Over-Voltage Protection (OVP) Setup
- Press the 'OVP' button to enter the OVP configuration interface. The display will show 'OFF' or 'ON' and the current OVP trip point.
- To enable OVP, press and rotate the 'CURRENT' knob to set the OVP status to 'ON'.
- Use the 'VOLTAGE' knob to set the desired OVP trip point (e.g., 40.00V).
- Press the 'OVP' button again to return to the main interface. The 'OVP' LED will be lit, indicating OVP is active.
- If the output voltage exceeds the set OVP trip point, the 'OVP' LED will flash, and the output will be disabled.
- To disable OVP, press the 'OVP' button, then press and rotate the 'CURRENT' knob to set the OVP status to 'OFF'. Press 'OVP' again to exit.
5.5 Over-Current Protection (OCP) Setup
- Press the 'OCP' button to enter the OCP configuration interface. The display will show 'OFF' or 'ON' and the current OCP trip point.
- To enable OCP, press and rotate the 'CURRENT' knob to set the OCP status to 'ON'.
- Use the 'VOLTAGE' knob to set the desired OCP trip point (e.g., 10.00A).
- Press the 'OCP' button again to return to the main interface. The 'OCP' LED will be lit, indicating OCP is active.
- If the output current exceeds the set OCP trip point, the 'OCP' LED will flash, and the output will be disabled.

- Storage: When not in use for extended periods, store the power supply in a cool, dry place, away from direct sunlight and extreme temperatures.
- Fuse Replacement: If the fuse blows, replace it with one of the same type and rating. Refer to the specifications for the correct fuse type.
8. Troubleshooting
- No Power:
a. Check if the power cord is securely connected to both the power supply and the wall outlet.
b. Ensure the main power switch is in the 'ON' position.
c. Check the fuse on the rear panel. Replace if blown. - No Output Voltage/Current:
a. Ensure the 'OUT' button is pressed and its LED is illuminated.
b. Check if OVP or OCP protection has been triggered (OVP/OCP LEDs flashing). If so, clear the fault condition and reset the protection or disable it temporarily for testing.
c. Verify that the voltage and current settings are not set to zero. - OVP/OCP LED Flashing:
a. This indicates that the Over-Voltage Protection or Over-Current Protection has been activated.
b. Reduce the output voltage or current setting, or check your load for faults (e.g., short circuit, excessive current draw).
c. To reset, turn off the output using the 'OUT' button, correct the issue, and then turn the output back on. - Overheating:
a. Ensure the cooling fan is operating and not obstructed.
b. Check for adequate ventilation around the unit.
9. User Tips
- Pre-set Limits: Always set your desired voltage and current limits before connecting a new or sensitive load to prevent accidental damage.
- Load Connection: Connect the load to the output terminals only after the power supply is turned on and the desired voltage/current limits are set, but before enabling the output.
- Auxiliary Output: Remember the auxiliary output is limited to 5A MAX. Do not exceed this limit.
- Protection Features: Utilize the OVP and OCP features to protect your circuits and the power supply from unexpected conditions.
