An einem Gehäuse für aeronautische Ausrüstung fixierbare Notstromversorgung

摘要

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.
