The VP-X

    Electronic Circuit Breaker System

    The Ultimate Solution for Easy Wiring

    Switch Your Thinking!

    The VP-X Electronic Circuit Breaker System is the best way to wire and fly your experimental and light-sport aircraft. This advanced, solid-state system enables easier airplane wiring, safer flying, and provides a better, more flexible solution than traditional thermal breakers or automotive-style fuses. 

    The VP-X is a Better Way to Wire and Fly Your Airplane

    The Vertical Power VP-X Electronic Circuit Breaker System gives you an unprecedented level of detail and control of your electrical system, while at the same time greatly simplifying wiring. With flap, trim and other functions built right into the VP-X, you just wire directly from the VP-X to each electrical device. You no longer have to install circuit breakers, bus bars, relays, trim and flap modules, shunts, e-bus diodes, or other complex wiring on the back side of the instrument panel.

    EFIS integration Provides a New Level of Information and Control

    Monitor and interact with your electrical system right on your EFIS. The Vertical Power integration means you know the health of your electrical system at all times.

    The VP-X System

    This system diagram illustrates how the VP-X (shown on the right side) is connected to your electrical loads and other components. Here it is receiving bus power from the Vertical Power PPS (Primary Power System). It can alternatively be connected to a traditional battery contactor. 

    Visit the Vertical Power System page for more information on the entire PPS/VP-X system.

    The Vertical Power System

    The only solid-state electrical system for experimental and light-sport aircraft.

    Vertical Power is the only solid-state electrical system designed specifically for use on experimental and light-sport aircraft. Whether you use the VP-X individually, or together with the PPS for an end-to-end system, you will be using the finest, most reliable electrical system available today.

    Choose From Two Models: VP-X Pro and VP-X Sport

    Not all planes are alike, so we don't take a one-size-fits-all approach with the VP-X.

    The Full-Featured VP-X Pro

    The best choice for larger aircraft or those who enjoy enhancing their aircraft with the latest advances in avionics in the future.

    The VP-X Pro is our most full-featured Electronic Circuit Breaker System. It includes 32 switched power circuits and the ability to handle both 14V and 28V systems, so it is ideal for the widest range of aircraft. It also features a dual-bank design with dual processors and power supplies for an added level of redundancy and safety. The extra circuits can also provide ample growing room for the future. 

    The Efficient VP-X Sport

    The best choice for medium size and under experimental aircraft. It's also ideal for light-sport aircraft.

    The VP-X Sport has just what you need for a wide-variety of aircraft from basic flyers up to the most popular kits being built today. It features 24 switched power circuits on a 14V bus. With the VP-X Sport, a builder gets all the benefits of the Vertical Power Electronic Circuit Breaker System – easier wiring, quicker installation, increased information and control, and more – for about the same as you would pay for a traditional thermal breaker system.
