Abstract

A power supply apparatus for use with an aircraft can include an aircraft interface input adapted for operatively connecting to and receiving DC power from an aircraft'"'"'s power bus, and a single connection input adapted for operatively connecting to and supplying power and communications to a plurality of aircraft devices. The apparatus can include a DC to DC electrical converter that converts the DC power received from the aircraft power bus and converts the power to appropriate voltages for powering the aircraft devices.

Claims

1. A power supply apparatus for use with an aircraft comprising:
