Mini EMP Defender 12V with test button

Designed with a test button so that that the status indicator lights do not have a drain on a battery electrical system. Great for use on Generators, equipment with small DC batteries or systems that do not get recharged on a regular bases.

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

This device is rated to protect against EMP, ESD, and CME 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.
