Many people wonder why the Switching power supply 30V shell is sometimes charged? Let's briefly take you to understand the three reasons for electrification:

good price and quality Switching power supply 30V on sales
(1) The manufacturing process of Switching power supply 30V is poor, and the FeCl3 used in making the circuit board is not completely cleaned. When the weather is humid, a conductive layer will be formed and the case will be charged. This situation is common in some low-priced switching power supplies, and the feeling of leakage is particularly obvious. In this case, the leakage is more dangerous, and the electric shock to people is more obvious and serious, so the power supply must be replaced in this case.
(2) In Switching power supply 30V, the center ground of the common mode filter capacitor is connected to the chassis, and the chassis is connected to the ground wire in the single-phase three-wire system. Capacitors have a certain impedance value, so more or less the casing will have a certain potential. If there is no ground wire installed, there will be a very obvious "electric shock" feeling when touching the casing in wet weather.
(3) Switching power supply 30V emits a large amount of high-frequency electromagnetic waves to the surrounding space during normal operation. These electromagnetic waves gather on the casing to form static electricity and accumulate. When there is a suitable discharge circuit and someone touches the casing, it will discharge to the outside , using the "shock" sensation that a person feels.
