A back up power supply for avionics equipment that can be installed in existing avionics equipment trays without having to rewire the aircraft. According to a preferred embodiment of the invention (described for illustrative purposes in the context of providing a power supply back up for a cockpit voice recorder (CVR)), the power supply/CVR combination is retrofit in an existing CVR rack. The power supply is, according to the aforementioned preferred embodiment, modular; removable/replaceable; and is "independent" relative to the main aircraft power source and wiring. The power supply/CVR combination is designed to fit into a conventional CVR tray; and the CVR is designed to fit into the modular power supply. Furthermore, according to a preferred embodiment, the power supply is "plug compatible" with the existing electrical connector in the CVR tray and includes circuitry which allows both the power supply and CVR to be tested using the existing CVR test button in the cockpit; and to report faults from either unit using existing aircraft wiring. Moreover, the power supply includes circuitry which automatically electrically disconnects it from the CVR and exposed pins when the power supply is removed from the CVR tray. The CVR and power supply of the preferred embodiment of the invention being modular are easy to install, require no cables, occupy approximately the same space previously occupied by the existing CVR, and have substantially the same center of gravity as the existing CVR. Integrated avionics/back up power supply units are also contemplated by the invention where the units are designed to fit into existing equipment trays to eliminate and/or minimize the need for re-wiring the aircraft.
