SKU: MAXEMP12V1 Categories: , , , ,

3 stage protection device designed for 12 Volt systems ONLY (Please verify correct application before ordering).

This device is rated to protect against EMP, ESD, CME, and Lightning damage. The EMP Defender 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 EMP Defender works like this by shunting the extra voltage away from your electrical circuit allowing it to operate as normal.

    I selected this product over the others on the market due to outstanding specifications and recovery time. I also liked the fact that it is bench tested during and after manufacturing.

    I purchased one of these for my Kenworth, I wanted something robust that would protect me while I’m going down the highway. I ordered one from their competitor first and returned it once I saw this one. This thing is built like a tank!!! Thank you Jon
