Faraday Defense DEFCON Vehicle EMP Protection 12V DC Circuit Protection

SKU CH-S7ZV-FQF86

12–15 V DC surge protector rated at 270,000 A and over 2,000 J with sub-nanosecond response for vehicle EMP, lightning and solar-flare defence

  • Protects 12-15 V DC systems from EMP, lightning, CME and solar flare events
  • Handles 270,000 A total surge current for extreme transient suppression
  • Absorbs over 2,000 J total energy to safeguard vehicle electronics
  • Activates in under 1 ns typical for near-instantaneous protection
  • 36-inch positive, negative and ground leads simplify installation in auto and truck applications

Vehicle EMP Protection

The Faraday Defense DEFCON unit provides 12-15 volt DC circuit protection for automotive and truck electrical systems. It is designed to guard against lightning strikes, coronal mass ejections, solar flares and general surge events. The device connects via positive, negative and ground wires measuring 36 inches in length. It suits owners seeking hardened protection for mobile 12V electronics.

Thermals and Power Draw

Typical current consumption is 9mA, imposing minimal load on the vehicle electrical system. The unit activates in less than one nanosecond to clamp transients before they reach sensitive components. A total surge current rating of 270,000 amps and an energy rating exceeding 2,000 joules indicate high single-event absorption capacity. No active cooling is required for normal operation.

Wiring and Form Factor

The three-wire harness uses 36-inch leads for flexible routing to battery or distribution points. Physical dimensions are 4.5 inches long, 3.375 inches wide and 1.875 inches high, allowing installation in confined engine bays or under dash areas. The compact enclosure supports permanent mounting without special brackets. No configuration software or accessories are included.

Questions about this item

How do I wire the positive, negative, and ground leads into a 12-15 volt DC vehicle system, and which step is most often missed?

Connect the three 36-inch wires to the battery or distribution block matching polarity, then secure the ground to a clean chassis point; the step most often missed is verifying that the ground contact is bare metal and torque-tight.

What maintenance or replacement will the DEFCON unit need after it absorbs a large surge?

The device is a sacrificial suppressor; after a major lightning, CME, or solar-flare event that exceeds its 270,000 Amp or 2,000 Joule rating, the internal elements must be replaced because they do not self-reset.

At what sustained current or temperature does the protection stop clamping effectively?

The unit is rated for 9 mA typical quiescent draw and clamps in under 1 ns; continuous over-voltage that keeps the device conducting beyond its energy rating will degrade the elements, so the first limit reached is the 2,000 Joule total energy capacity.
