EMP Shield is an EMP protection technology for your vehicle. Tested to military and UL 1449 standards from ETL and built to exceed military standards (MIL-STD-188-125-1, MIL-STD-464C, and MIL-STD-461G), The EMP Shield is one of the World’s fastest whole home surge protectors operating in less than 1 billionth of a second. Our devices have been military tested and proven to defend against the E1, E2, and E3 phases of an electromagnetic pulse. EMP Shield is designed to protect an entire home from lightning, a solar flare (coronal mass ejection), power surges, and electromagnetic pulses. EMP Shield's family of technologies has been tested at Keystone Compliance, in accordance with all military standards. EMP Shield will protect all the electronics and equipment connected to your electrical system. This is accomplished by shunting (shorting) the overvoltage coming in from the grid and the voltage surges that are collected within your home.
