EMP Defender, Surge Defender, and Lightning Shielding Questions
What is an EMP or Surge Defender?
A device that is used to prevent damage to electronic circuits and devices during over voltage conditions.
What causes Over Voltage conditions?
There are many ways this can happen, from common daily activity to rare devistating events. Here are just a few.
EMP (Electromagnetic Pulse) These can be tiny from something as simple as overhead powerlines to as large as a Nuclear explosion.
Link: Electromagnetic pulse
ESD (Electrostatic Discharge) Similar to the shock you get when touching a metal object in dry weather conditions.
Link: Electrostatic discharge
CME (Coronal Mass Ejection) A burst of plasma and accompanying magnetic field, ejected from the sun towards the earth.
Link: Coronal mass ejection
LEMP (Lightning Electromagnetic Pulse) A nearby Lightning strike produces a magnetic field capable of damaging electronics even without direct contact.
MEMP (Meteoric Electromagnetic Pulse) The explosive breakup of a meteoroid passing through the Earth’s atmosphere.
How does it work?
By shunting the high voltage away from the protected electronics.
Link: Electrical shunts
Think of it as a flood gate on a lake. Once it reaches a certain level the extra water is diverted away and the lake level stays at a safe maximum level.
Why do I need one?
Well hopefully you never do, but for the money it’s well worth the peace of mind knowing that it is there to protect you.
What can an EMP or Surge Defender protect?
Cars, Trucks, etc...
CB and Amateur Radio Equipment
Have these been tested to work?
That components we use in our devices are sourced from companied such as Littelfuse, Bourns, Micro semiconductors, Vishay, Texas instrument, and more. Below are just a small portion of the testing that has been completed.

On top of their testing we provide our own testing with actual EM (Electromagnetic) pulses applied to each device to verify correct operation so you can trust the EMP Defender will be there to protect you when it is needed.
What about other Military testing like MIL-STD-188-125-1, MIL-STD-464C, and MIL-STD-461G?
MIL-STD-188-125-1 standard establishes minimum requirements and design objectives for high-altitude electromagnetic pulse (HEMP) hardening of fixed ground-based facilities that perform critical, time-urgent command, control, communications, computer, and intelligence (C4I) missions. This rating involves adding protection to communication lines, power lines, and provide metal shielding on a building to protect the structure from exterior EM effects.
MIL-STD-464C standard establishes electromagnetic environmental effects (E3) interface requirements and verification criteria for airborne, sea, space, and ground systems, including associated ordnance. In short, MIL-STD-464 is a collection of baseline system- and platform-level requirements and verification methods for fully assembled systems – the submarine, the launch vehicle, the surface ship and the others mentioned in MIL-STD-461
MIL-STD-461G standard establishes interface and associated verification requirements for the control of the electromagnetic interference (EMI) emission and susceptibility characteristics of electronic, electrical, and electromechanical equipment and subsystems designed or procured for use by activities and agencies of the Department of Defense (DoD). The MIL-STD-461 document is applied to electrical or electronic systems of rugged servers and workstations, used in military programs and applications.
The difference between MIL-STD-461 and MIL-STD-464, is the former addresses specific pieces of equipment and subsystems, and the latter addresses systems and platforms at large.
I see there are other companies making similar products, how are yours different?
Each product is specifically designed and built for its application.
DC (Direct Current) systems operate using a Positive (Red wire) and a Negative (Black wire). That is why our DC systems only have 2 wires where other Manufacturers may have 3 wire.
AC (Alternating Current) systems require two power wires called Line (Typically a Black or Red wire) and Neutral (Typically a White wire), plus a third wire that is connected to Earth ground (Typically a Green wire).
Our products are smaller than our competitors.
More energy efficient.
Wider variety of options available including custom built for customer specific needs.
