7. Troubleshooting
If you encounter issues with your power supply, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power output / Indicator light off | Power outlet not active, loose connection, faulty unit. | Check wall outlet with another device. Ensure all cables are securely connected. If issue persists, the unit may be faulty. |
| Device not powering on or flickering | Incompatible voltage/wattage, device fault, overloaded power supply. | Verify your device requires 12V DC and its wattage is ≤120W. Reduce the load if multiple devices are connected. Test with another compatible device. |
| Power supply feels hot | Normal operation under load, poor ventilation, excessive load. | Ensure adequate ventilation around the power supply. Reduce the connected load if it consistently feels excessively hot. The unit has over-temperature protection. |
| DC plug does not fit | Incorrect DC jack size. | This power supply uses a 5.5x2.1mm DC plug. Verify your device's input jack size. |
If troubleshooting steps do not resolve the issue, please contact BTF-LIGHTING customer support.
