Now many units have installed the program-controlled switchboard, and the most important part of the program-controlled switchboard is integrated circuit (IC). IC anti-interference ability is low, even if from the line induction Lightning electromagnetic pulse (LEMP), can also penetrate IC components. Therefore, the program-controlled switches are prone to lightning accidents. The most damaged parts are the relay board, the user board, the billing card and the power supply section. Because of th
