7. Troubleshooting

If your LED lights are not functioning correctly with the Nehbujin power supply, consider the following:

• No Power:
  • Check if the wall outlet is functional by plugging in another device.
  • Ensure the power supply is fully inserted into the outlet.
  • Verify that the GFCI receptacle has not tripped. Reset if necessary.

  • Polarity Mismatch: Some LED lighting systems are sensitive to polarity. Carefully check the positive (+) and negative (-) markings on both your LED lights' connector and the power supply's connector (as shown in Section 4). If they are reversed, the lights will not work. This power supply has a specific polarity configuration.
  • LED Light Malfunction: Test your LED lights with a known working power supply if possible, or test the power supply with another compatible LED light set to isolate the issue.
  • Overload: Ensure the total wattage of your connected LED lights does not exceed the power supply's maximum output of 8W.
• Flickering Lights:
  • Check for loose connections between the power supply and the LED lights.
  • Ensure the power supply is not overloaded.
