10. Troubleshooting
If you encounter issues with your converter, consider the following:
- No Output Voltage:
- Check input voltage to ensure it is within the 8V-35V range.
- Verify input polarity (Red to +, Black to -).
- Check for short circuits in the output wiring or load. The device has short-circuit protection, which may temporarily shut down output.
- Ensure the load does not exceed 3A/15W.
- Output Voltage is Unstable or Incorrect:
- Confirm input voltage stability.
- Check for loose connections.
- Ensure the device is not overheating. Over-temperature protection may reduce output.
- Device Overheating:
- Ensure adequate ventilation around the converter.
- Reduce the load if it is consistently near the maximum limits.
