Critical Infrastructure
Low Voltage HEMP Filters

Society depends on critical infrastructure like power grids, military monitoring, and water processing plants. In applications where disruption can mean disaster, high levels of protection are necessary.

TSS USA Manufacturing’s LV low voltage HEMP filters meet the highest protection standards:

  • MIL-STD-188-125-1A
  • UL1283 (in process)
  • MIL-STD-188-125-2
  • Low Voltage Directive
  • MIL-STD-220
  • MIL-F-15733

In high-security, heavily regulated applications, and commercial proprietary applications—military and national security, healthcare, finance, energy, transportation, communications, and industrial—HEMP-rated filters provide protection from an electromagnetic pulse (EMP) or high-altitude electromagnetic pulse (HEMP) event.

A brief bombardment coming from lightning or an electrostatic discharge, the switching on of a power source, or even intentional generation, like with a powerful special electronic weapon or a nuclear warhead detonated high up over the planet, can temporarily disrupt a device or even permanently damage it.
When discussing critical infrastructure—perhaps military important military equipment monitoring the safety of the country or maybe a commercial installation providing power, a water processing plant, cloud computing for companies, telecommunications, food, transportation, energy, or other important services—the potential for EMP is important to safeguard against.

Two ways this is done is with shielded equipment of facilities and grounding to divert unexpected impulses into the earth, bypassing the equipment that needs protection.

But there is a third way an EMP pulse can do serious damage to communications, power, and other electronics equipment and services and even destroy equipment at a distance: it can hitch a ride on incoming cables or wires.

They are conductors, and the EMP hops aboard as though it were a commuter train and ride, without distraction, into equipment it can disrupt or damage.

There are up to three EMP components: E1 short duration (nanoseconds to microseconds) pulse, E2 effects similar to lightning (microseconds to seconds), and E3 (seconds to minutes) like an extremely intense solar flare.

To protect against high altitude EMPs, organizations can incorporate the use of HEMP-rated filters. HEMP filters also protect from EMP that other sources closer to the ground generate. Such protection can prove useful either for military and security or public sector use.

The low-voltage versions of TSS HEMP filters, running at voltages of up to several hundred volts and typically within ambient temperature ranges of -40°C to 50°C.

TSS USA Manufacturing operations are in the U.S.A. and source raw materials and components predominately from the U.S. to serve your critical operations. TSS filters meet the FAR 52.225-1 Made in America.
