6 Methods Of Solving Common Ultra-Thin LED Power Supply Issues


The ultra-thin LED power supply is significant in the operation of various LED lighting systems. The drivers, such as the switch mode power supply, convert unregulated direct current to a regulated one. There are some cases where the power supply may fail to work efficiently. In such cases, the light strips may dim, there may be power supply failure or electrical fires. Below are some common issues present in the ultra-thin LED driver and how to solve them.

1. Failure of the ultra-thin LED power supply to work well at high temperatures

There are situations where your LED power supply cannot work efficiently at very high temperatures. Most LED drivers’ output drops in environs with 50 degrees temperature and above. Some LED driver’s specification indicates that de-rating is rare. The drop can be an output power of between 50% and 100%. To solve the issue, you can always install extra power supplies. The extra drivers can compensate for the drop in the efficiency levels.

2. Incompatibility issues

There are instances where your power supply and the LEDs device are incompatible. For example, the 24V DC cannot work well with the 12V LED strip. Therefore, check whether the LED strip and the power supply are compatible in such a situation. Also, before you buy a power supply, always ensure that it will be compatible with your LED strip.

3. An ultra-thin LED power supply that is not entirely waterproof

An outdoor power supply that quickly catches water can be hazardous in some situations. Therefore, ensure that your power supply’s design is for outdoors. If it is not waterproof, you can always make a waterproof enclosure to protect your LED driver. It will cost you extra money to ensure waterproofness. But, you can always buy a waterproof, ultra-thin LED power supply for safety purposes.

4. Flash off and on of the power supply

There are some instances where the power supply can flash off and on or even fail. In such cases, check the output and input power. The output and input power should be compatible with your installation requirements. You can find information on the power at the back or front of the driver. If you over-drive your power supply, it may flash off and on or fail to work ultimately.

5. Loose connections

Loose connections are another common problem that drivers may have. Double-check and see whether all the wires and connectors are in their suitable place to solve the problem. To avoid loose connections, you can also tighten up the DC adapter’s screws.

6. Inappropriate ultra-thin LED power supply mounting issues

Inappropriate mounting can lead to power supply operation failure. The critical point is that different power supplies and projects have varying mounting requirements. If you ignore the requirements, then there is a high chance that your power supply will not function efficiently. For instance, some power supplies need to face up during installation. The main aim of the mounting direction is to allow free air movement. Also, it would help if you did not mount the waterproof power supplies facing the sun.


Most ultra-thin LED power supply issues are not because of the inefficiency of the power supply. But, the failure of not reading the specifications carefully. The above common problems will help you identify what to avoid and what not to.
