The use of switch mode power supplies is becoming increasingly widespread, especially in high-tech applications, which has promoted the development of high-tech and is very helpful in saving energy, resources, and environmental protection. The rainproof switch power supply has significant implications, and here I can introduce some common knowledge about it.

The rainproof switch power supply includes a box body, a switch power supply, and a switch power supply adapter board. Its box body consists of a bottom shell and a top cover. Its bottom shell is a U-shaped end surface composed of a bottom plate and two side plates, and at least one screw fastening groove is provided on the inner side of the bottom plate for fixing the switch power adapter board; There are also cover sliding grooves on the two outer sides of the side panel that cooperate with the bottom shell sliding groove. Inner circular grooves are provided near the four corners of the bottom shell to fix the upper and lower covers. Install exhaust holes at the locations corresponding to the fan holes on the face cover and switch power supply. Then, install a rain cover on the exhaust holes, and set up a wiring hole on the lower cover. At least one water outlet should be provided on the lower cover. This not only prevents rainwater from entering the box, but also greatly improves the heat dissipation effect.

Many friends don't know how to connect this power supply, but here you can also teach us. Firstly, connect V to the positive pole of the switch, V - to the negative pole of the switch, and then connect L and N to the position of the AC220V terminal, which is very simple and convenient.

Some friends' purchased power supplies always show signs of burning out, probably not due to the switch itself. I need to check if the load is malfunctioning. Due to the fact that 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 the load has poor contact, connect the wires properly to ensure that there is no sparking phenomenon, and then check if it has aged and rusted. 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 selecting the power board, we should also pay more attention to prevent the situation of inferior products being sold as good. 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. 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, we must remember that you get what you pay for, and choose products with guaranteed quality.

The above is some common knowledge about rainproof switch power supplies, hoping to be helpful to us.
