Abstract
An electro-magnetic pulse (EMP) protection circuit with a counter has a surge protection circuit capable of suppressing EMP, and also use an extra counting circuit for sensing light emission or variation of magnetic force of the surge protection circuit to count the action times of the surge protection circuit, thereby warning that the surge protection circuit has reached its usage limit and has to be replaced. Therefore, protect a variety of electronic products perfectly to avoid greater losses.
