Cabin Power System
Components
With newer aircraft having a 28 V electrical systems and older aircraft not having a cigarette lighter, the possibility of plugging in your personal portable electronic devices such as laptop computers, CD players, hand-held GPS units and backup radios to keep from depleting the internal batteries is no longer an impossible feat. The Cabin Power System provides a 12V outlet in the cabin.
The Cabin Power System consists of a Voltage Regulator Unit (VRU) assembly that is connected to a power outlet mounted within the aircraft cabin. The VRU (shown above) converts aircraft power to 12V at 1.5A at the outlet. With its small size (2 7/8" L x 3 ½" W x 2 1/8" H) and weight (only 5 oz) the VRU can easily be mounted in a variety of locations. In Cessna 172, 182, and 206 models it is approved for mounting on top of the map compartment behind the instrument panel. The VRU is installed with a minimal amount of wires and hardware.
The outlet is a 9-pin circular connector, which meets ARINC 628 Part 2 requirements for commercial airline in-seat power connectors. An adapter cable that goes from the ARINC 628 connector to a cigarette-lighter style connector is also available.
The Cabin Power System is currently STC-PMA'd for Cessna 172, 182, and 206 models. The system is shipped complete with a Flight Manual Supplement, Instructions for Continued Airworthiness, and an Installation Manual in hard copies and on a CD-ROM. It can also be installed on other aircraft under a field approval.
