- Fuse Replacement: If the power supply does not turn on, check the fuse located in the power socket on the back panel. Replace it with a fuse of the same type and rating if necessary.
- Storage: When not in use for extended periods, store the power supply in a cool, dry place away from direct sunlight and excessive dust.
6. Troubleshooting
This section addresses common issues you might encounter with your BSIDE I8 Series power supply.
6.1 Protection Mechanisms
Figure 6: Six Major Testing Protections
The power supply is equipped with six major protection functions:
- Over-Voltage Protection (OVP): If the output voltage exceeds the set OVP limit, the output will be cut off. The display will show "OVP" and the output will be OFF.
- Over-Current Protection (OCP): If the output current exceeds the set OCP limit, the output will be cut off. The display will show "OCP" and the output will be OFF.
- Overload Protection: Protects against excessive power draw.
- Over-Temperature Protection: Shuts down the unit if internal temperature becomes too high.
- Short Circuit Protection: Prevents damage in case of a short circuit at the output.
- Polarity Reverse Protection: Protects against incorrect polarity connections.
If any protection is triggered, identify and resolve the underlying issue (e.g., reduce load, check for short circuits) before re-enabling the output.
6.2 Common Issues
- No Power: Check the power cord connection, the main power switch, and the fuse on the back panel. Ensure the 110V/220V switch is set correctly.
- No Output: Ensure the "OUTPUT" button is pressed and the output is enabled. Check if OVP or OCP has been triggered.
- Unstable Output: Verify that the load is within the power supply's specifications. Check for loose connections.

8. User Tips
- Utilize Memory Presets: For frequently used voltage and current combinations, save them to the M1, M2, or M3 memory slots for quick recall, saving time during repetitive tasks.
- Monitor Output Status: Pay attention to the "CV" (Constant Voltage) and "CC" (Constant Current) indicators on the display to understand the current operating mode of the power supply.
- Check Protection Settings: Always set appropriate OVP and OCP limits before connecting sensitive loads to prevent damage.
- Keep Ventilation Clear: Ensure the cooling fan and vents are unobstructed to maintain optimal performance and prolong the lifespan of the device.
- Use USB Communication (I84020/I83010): If your model supports it, connect to a computer via the USB serial port for advanced programming and data logging, enhancing control and analysis capabilities.
