Shop name:Chong Qing Shuo Yue Ke Ji You Xian Gong Si 1) Add an overvoltage protection circuit to prevent high voltage. 2) Use a set of differential mode filters and two differential inductors to perform differential mode filtering on the AC power supply to suppress mid- and high-frequency interference. 3) Three sets of common mode filters are combined by X2 capacitor and common mode inductor to form a common mode filter. Due to the use of three-level (also known as three-level) filtering, the effect of filtering out noise is better. It can effectively suppress the fast transient group pulse interference problem of some user sites with a repetition frequency of several thousand hertz.
