How Has EMP Shield Been Tested?
Isn’t a nuclear explosion required to create an EMP?
The threat of an EMP is the large amount of electricity that is induced into conductors that generate heat and can be destroyed. There are only a few testing facilities in the world capable of producing the same amount of electricity that an EMP produces.
EMP Shield has been designed to exceed the US Military requirements for protection against a high-altitude nuclear detonation that results in an electromagnetic pulse. This family of products has been tested to verify compliance with the following Military Standards:
MIL-STD-461-RS105 Transient electromagnetic pulse of up to 50 kV/m, double exponential wave with a rise time in the nanosecond range, that is applied to the equipment under test (EUT) at least 5 times. We tested at 50 kV/m and also 90 kV/m (80% above required testing voltage).
MIL-STD-188-125-1 High Altitude EMP
MIL-STD-461G Control of Electromagnetic Interference
MIL-STD-461-CS-115 The purpose of CS115 is to test an electronic or electrical system to withstand signals coupled onto the test unit’s associated cabling. The test unit will be subjected to rise and fall times, pulse width, and amplitude as specified on Figure CS115-1 at a 30 Hz rate for one minute;
MIL-STD-461-CS116 applies to 10 kHz to 100 MHz for all interconnecting cables, including power cables, and individual high side power leads;
MIL-STD-461 CS117 apples to all safety-critical equipment interconnecting cables and non-safety critical equipment with interconnecting cables/electrical interfaces that are part of or connected to equipment performing safety critical functions. The goal is to test the unit’s ability to withstand lightning transients coupled onto the test unit’s associated cables and power leads;
MIL-STD-464C Electromagnetic Environmental Effects Requirements for Systems.
Our test results show that we begin shunting the over-voltage condition in less than 1 nanosecond, and our units are designed to shunt over 100,000 Amps per phase. Our devices are scalable to any size.

How Does EMP Shield Work?
EMP Shield will protect all the electronics and equipment connected to your electrical system.
This is accomplished by shunting (shorting) the over voltage coming in from the grid and the induced voltage that is collected within your home.
Whether the source of electrons are from within your home or coming into your electrical system from outside the home (the grid), the Shield will see the surge and protect your electrical system. Our technology reacts in less than 1 billionth of a second. Since the shunting is completed incredibly fast, the over voltage is drained away from the equipment before the voltage can rise high enough to damage any equipment. We call this new technology SightSpeed™

Just a little insurance policy. Hope it’s never needed, but cheaper than repairs if it is.
Dan Mason (verified owner) –
Received quickly, well packaged, great support from staff. Looking forward to installing and getting protection up and running. Thanks guys and gals!
Joe (verified owner) –
Most US military bases have now completed off grid backup power support, only makes sense to try to protect the device we may come to depend on for various power outages.
