Part of the purchased Switch Power Supply always burns out. First check if the load is faulty. Because the switching power supply is generally outdoors, the parts that are blown by the wind are prone to problems. Then we need to see if there is a bad contact in the load and ensure that there is no sparking. If the above two problems do not occur, then see if the aging is rusting. Replace parts of this type if there is a leakage.
When purchasing the rain-proof switching power supply, we must choose a good quality and guaranteed power supply. When selecting the power supply board, pay more attention to it to avoid the situation of sub-filling. The inferior products on the market use half-wave lead plates. This will make the LED Waterproof power supply have a shorter service life, and the regular service life will be longer. At the same time, many inferior products are made of second-hand components. Once they are used for a long time, they will explode. It is a very dangerous situation, so we must choose products with guaranteed quality.
