Primary Power System, PPS

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.

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).

p/n. KT1458-1

the Kit is composed by:

1 PPS, Primary Power System;

1 Vertical Power Information card (p/n. 81002-1);

1 kit wiring harness (p/n. KT1458-1-002);

1 kit hardware accessory (p/n. KT1458-1-003)

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.
