Max DC Surge Protector 150V

3 stage protection device designed to protect DC electrical systems ONLY (Please verify correct application before ordering).

This device is rated to protect against EMP, ESD, CME, and Lightning damage. The surge protector works like a flood control gate on a lake. On a lake once the water level reaches a maximum level the extra water is diverted and the lake level is maintained at a safe level. The surge protector does this by shunting the extra voltage away from your electrical circuit allowing it to operate as normal.
