Primary Power You Can Count On

Finally, a simple and reliable primary power solution.

The Vertical Power Primary Power System (PPS) is an entirely new approach to the master, starter, and charging circuit on your experimental aircraft or LSA. It combines the functions of multiple high-current, electro-mechanical components into a single, solid-state device that installs in minutes with plug-and-play simplicity. Plus, the high-reliability of the PPS means you won't find yourself stranded on a deserted landing strip without the power to start your plane.

What is the PPS?

The PPS is a new power distribution component that handles your aircraft's high-current power. It controls the flow of power from the battery to the starter and supplies power to the Vertical Power VP-X (or a traditional bus) for your electrical system loads. The PPS also supports the charging circuit by completing the B-lead connection to the alternator (a basic system diagram is provided below).

There Is No Comparison

Until now, your only primary power choice was the "old way", a combination of electro-mechanical components that haven't significantly changed in half a century.

Now you have a choice...the PPS.

The PPS is a carefully-engineered and highly-qualified device that eliminates the need for you to engineer and manufacture your own primary power circuit. This not only puts an end to common errors in homemade circuits, but the solid-state construction of the PPS proivdes extremely high reliability when compared to the failure-prone solenoids, relays and contactors used in traditional circuits. In addition, the plug-and-play design of the PPS installs in minutes, saving you valuable time and allowing you to fly that much sooner.

The Primary Power System Diagram

The PPS, shown on the left side of this diagram, can be installed or retrofitted on an experimental aircraft equipped with the VP-X Electronic Circuit Breaker System or a traditional electrical bus. Visit the Vertical Power System page for more information.

The only solid-state electrical system designed 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 PPS individually, or together with the VP-X for an end-to-end system, you will be using the finest, most reliable electrical system available today.

The PPS Benefits

Whether you are an experimental aircraft builder or an LSA manufacturer, the new PPS provides many unique and important benefits. High reliability and easy installation are just the start. Take a look at the lists below to see why the PPS is truly easier, safer and better than traditional components.

• Speeds installation – easily mount one box instead of 5 or more individual devices.
• Saves space – smaller than the old-style individual components mounted together on the firewall.
• Clearly labeled for quick connection to electrical system.

• Reduces exposure to components at battery voltage.
• Eliminates hazardous and costly wiring mistakes.
• Highly engineered and proven design – no need to solve the challenging puzzle of what components you need and how they should be connected.

• Delivers higher reliability – replaces older mechanical contactors with solid-state technology.
• Low static power draw of 1 mA – won't drain your battery if you forget to turn off your master switch.
• Integrates perfectly with the Vertical Power VP-X system for a comprehensive solid-state electrical solution.
