Vertical Power Primary Power System

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. 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 provides 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.


General Specifications

  • Transient protection on all connections
  • The PPS is compatible with systems using a backup alternator in parallel with the primary alternator. The PPS is not compatible with two-bus systems.
