Bycan 14/28-Volt Red Baron Avionics Auxiliary Power Unit
Having an auxiliary power unit on aircraft is a smart move. APUs are great during ground operation and maintenance work, to power aircraft systems, but even better is when they can provide backup power in flight in the event of an outage. The Bycan RB-14/28-25 Red Baron APU is designed for efficient operation of aircraft avionics. Auxiliary power unit receptacles aboard the plane will accept this device, which comes equipped with either the Piper coaxial connector or the standard 3-prong connector. With a small additional cost, both connectors can be included. The APU's voltage is filtered, eliminating hum and it's regulated against changes in the input AC line voltage.
