Equip your vehicle with the Faraday Defense T.R.A.P.-B, a compact yet powerful transient voltage suppression device designed to shield your car’s sensitive electronics from high-voltage threats like lightning strikes, EMPs, and other conducted transients.
As a critical component for vehicle protection, the T.R.A.P-B attaches directly to your battery terminals, offering a reliable defense that ensures your vehicle's operation and electronics remain safeguarded. Hand-assembled in the USA using premium, automotive-grade materials, this device is ideal for anyone looking to enhance their vehicle's resilience against sudden electrical disturbances.
The Faraday Defense T.R.A.P-B is a specialized protection device that guards your vehicle’s electrical systems from dangerous voltage surges that can cause extensive and costly damage. Transient voltage surges, whether from load changes, external charging sources, or environmental events, can interrupt a vehicle's systems or, in worst cases, leave you stranded. By installing the T.R.A.P-B, you can ensure your vehicle's electronics are fortified against such unpredictable risks, offering peace of mind no matter the conditions on the road.
The T.R.A.P-B's small form factor packs a powerful transient voltage suppression capacity of up to 5,000 watts, making it suitable for most vehicles. By mitigating short-term, high-voltage events, the T.R.A.P-B helps prevent damage from conducted transients and high-energy events, protecting both your vehicle's functionality and your investment.
With the T.R.A.P-B, your vehicle is safeguarded from EMP events and electrical surges caused by environmental and mechanical sources. This technology intercepts brief but damaging voltage spikes, preventing harm to your vehicle’s sensitive electronics.
The T.R.A.P-B comes with IP68-rated ring terminals, which fit most vehicle batteries with ease. Its compact design ensures it doesn’t interfere with your engine setup, and its weatherproof packaging allows it to perform reliably under various environmental conditions.
Thanks to its efficient design, the T.R.A.P-B only draws power when necessary, ensuring your battery remains unaffected during regular operation. This means you can leave it installed permanently without worry of battery drain.
Even when your vehicle is powered down, the T.R.A.P-B remains active, continuously shunting any high-frequency transient energy. This ensures that any potential voltage threats are neutralized, even when you’re not in the car.
The T.R.A.P-B’s construction includes automotive-grade wires, copper terminals, and marine-grade heat shrink. Designed for rugged use, it meets AEC Q101 qualifications, ensuring resilience even in harsh weather or road conditions.
Faraday Defense provides a limited warranty policy, ensuring the absence of defects in materials, workmanship, and performance during the warranty period.
The danger to vehicles from an EMP is the high voltage that is introduced on the cables from E1 and E2. Those transient voltages are extremely brief in time (from nanoseconds to microseconds) and can therefore be suppressed using small devices. This is distinctly different than the case with homes, which would also experience a powerful E1 current surge from the power grid.
Yes, putting energy “traps” at multiple points in your vehicle does a better job shunting away the unwanted energy. Maximum protection is achieved by using a T.R.A.P.™ in every auxiliary power outlet, as well as using the T.R.A.P.™-B across the vehicle’s battery.
The T.R.A.P.™ provides transient protection even with the ignition switch turned off because interconnected cable assemblies can still receive damaging energy. The T.R.A.P.™ continues to act as a high-frequency energy sink even when the vehicle is unpowered.
T.R.A.P.™ products draw essentially zero current except when there is a significant overvoltage, so they won’t drain your battery.
