Some friends' purchased power supplies always experience burning out, probably not due to the switch itself. I need to check if there is a fault with the load. Because switch mode power supplies are usually located outdoors, parts exposed to wind and rain are prone to problems. We need to check if there are any damaged parts in the load, and if so, replace them. Next, we need to check if there is poor contact with the load, connect all the wires properly to ensure that there is no sparking phenomenon, and finally check if there is aging and rusting. If there is a leakage, such parts should be replaced.

When purchasing a rainproof switch power supply, we should choose a high-quality and guaranteed power supply. When choosing, we should also pay more attention to the power board to avoid the situation of replacing inferior products with good ones. The inferior products on the market use half wave lead plates, which will shorten the service life of the switch power supply, while the regular service life will be longer. At the same time, many low-quality products are manufactured using second-hand components, and once used for a long time, they can explode, which is a very dangerous situation. Therefore, everyone must remember that you get what you pay for, and choose products with guaranteed quality.
