Electromagnetic Pulse Protection Modules

We manufacture a wide range of products to protect against the effects of high altitude detonation of Nuclear devices.

The result of such an event is tHigh Altitude Electromagnectic Pulse Illustrationhe generation of electromagnetic pulses, which induce a high voltage transient in exposed conductors. The resulting EMP may affect several thousands of square kilometres, with a magnitude of tens of kilovolts, and can result in serious damage to insulation, breakdown of semiconductors, and the consequent malfunction of critical equipment such as Energy Power Supply and Communications Systems.

  • From low-voltage telecommunications and signal lines to high-current and voltage installations.
  • From 10v, 5A continuous with a maximum surge current capability of 4.5kA  - (8/20µs), up to and including 500v, 600A continuous, with a 50kA maximum surge.
