Overview
|
The D B Assembly, Inc R-14/28-25 APU is designed to operate avionics equipment in private and commercial aircraft.
The R-14/28-25 will output 14 or 28 volts DC at up to 25 amperes. The voltage is filtered to eliminate hum and is regulated against input AC line voltage changes. The output DC voltage and current are displayed on front panel meters. The DC is also protected by a circuit breaker. Selection of output voltage is by a front panel switch, which is protected by a switch guard. Closing the guard forces the switch to the 14-volt position. The RB-14/28-25 plugs directly into the APU receptacle on the aircraft. It comes equipped with either the standard three-prong connector or the Piper coaxial connector. Both connectors can be supplied, optionally at a slight extra cost. DC cable length is 8'. The AC line cord is normally 8' in length, but special lengths up to 50' are available. The housing is steel, powder coated in red, for optimum flight line safety. Rubber feet and handle are included. |
