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

This device protects your electrical system from:

EMP (Electromagnetic pulse)

EMPs are Intense bursts of electromagnetic energy that can be utilized to damage electronics. Man-made nuclear EMP are impressive weapons of war that are sparingly used due to their highly destructive nature.

ESD (Electrostatic discharge)

Electrostatic discharge (ESD) is the sudden release of electricity from one charged object to another when the two objects come into contact. While we’ve all experienced ESD when we’ve been shocked by a metal doorknob or car door, most ESD strikes are quite harmless to humans. However, for sensitive Electronic circuits, the high peak voltage and current of these ESD strikes can cause catastrophic failures.

CME (Coronal mass ejection, a.k.a. Solar Flares)

The sun could be one of our biggest threats in the next 100 years. If an enormous solar flare like the one that hit Earth 150 years ago struck us today, it could knock out our electrical grids, satellite communications and the internet.
