OVPD-TM Over Voltage Protection Device with Test Mode
$149.00
This device is designed to “crowbar” the Circuit Breaker by applying a short circuit electronically and “pop” the current Alternator Field Circuit Breaker when voltage is over 16 Volts to protect all of your electronics in your vehicle.
Planes these days have expensive electronics, from glass panels to lithium batteries, that need to be protected from an over voltage occurrence if your regulator fails. Your regulator controls the voltage output of your charging system, and if you have “unregulated” voltage event, your charging system can exceed the level of protection your electronics have and permanently damage them.
Some charging systems have over voltage protection as a standard feature, while others such as automotive engines do not. This device works as a crowbar that will automatically and instantly shut your alternator off once the voltage exceeds 16.1V so that high voltage levels do not reach your electronics and destroy them. This can also easily be added to a charging system that does have over voltage protection so you have redundancy. This is the safest and easiest way to protect you electronic investments in your plane.
This device is designed to “crowbar” the Circuit Breaker by applying a short circuit electronically and “pop” the current Alternator Field Circuit Breaker when voltage is over 16 Volts to protect all of your electronics in your vehicle.
The OVPD-TM is easy to install
1- Determine a suitable mounting location near the Alternator Field circuit breaker (CB), and mount. Often Velcro or a Nylon tie will suffice under your panel.
2- Connect the RED wire to the LOAD side of the circuit breaker. This is the side going to the alternator, not the bus. Use the included ring terminal.
3- Connect BLACK wire to a local ground. Aircraft ground or a ground block. Again, use the included ring terminal.
4- For the Test Mode Button (TMB) Model, use the included push-to-test switch to test the OVPD.
5- Push the Circuit Breaker back in to reset the device after the test.

BB-TH-U Thermal Battery Box “U” Case
Thermal battery box to protect from radiated or convection heat. This battery box is designed to be compatible with our existing “U” case battery models; ETX1600, ETX900-24, ETX680-24-VNT.
The EarthX thermal battery box is designed to protect the battery in engine compartment installations from periods of high temperature (up to 1 hour), such as after shutdown, and from radiant heat from hot surfaces like exhaust systems during and after flight. This stainless-steel box has a mirror finish to minimize the effect of radiant heat, and it has a high-performance insulating foam layer between the box and battery to reduce effect of convection heat. Weight is .68Kg or 1 Lb. 8oz.
All batteries have optimal temperature ranges for use in operation. The ETX-Hundred series is rated for 140 deg F (60 deg C) or less for optimal longevity and performance of the battery. Typical lead acid batteries are rated to 113 deg F or 45 deg C.
BB-TH Thermal Battery Box “E” Case
Thermal battery box to protect from radiated or convection heat. Fits the “E” case batteries including ETX680/ETX900/ETX900-VNT/ETX1200. Designed to protect the battery in engine compartment installations from periods of high temperature (up to 1 hour), such as after shutdown, and from radiant heat from hot surfaces like exhaust systems during and after flight. This stainless-steel box has a mirror finish to minimize the effect of radiant heat, and it has a high-performance insulating foam layer between the box and battery to reduce effect of convection heat. The hold-down tab comes with a mounting fixture that can hold a cooling air duct up to 1” in diameter. This battery box was engineered to be strong enough to withstand 30 G of force yet only weighs .49Kg or 1 Lb. 1.2oz.
All batteries have optimal temperature ranges for use in operation. The ETX-Hundred series is rated for 140°F ( 60ºC) or less for optimal longevity and performance of the battery. Typical lead acid batteries are rated to 113ºF or 45ºC.
BB-MU2 Light Weight Aluminum Battery Box
The light weight aluminum battery box is excellent to use with the EarthX lithium “E” case batteries for easy installation. Has a bolt-down tab for easy removal of the battery from the front or top, and is acrobat rated (even with PC680).
This battery box can be used with: ETX680, ETX900, ETX900-VNT, ETX1200, and Odyssey’s PC680
