Abstract
Battery back up system is disclosed for powering a wall transformer when a power supply failure occurs. The system comprises a back up battery connectable to the wall transformer to provide power to the device powered by the wall transformer, upon a power interruption. The system may include an adaptor into which the backup battery and wall transformer may be connected. The adaptor may be connected to a conventional AC power source. Other embodiments of the invention allow a backup battery to be directly connected to the wall transformer.
Claims8
A battery backup system for powering a wall transformer when a power supply failure occurs comprising:
- a) a backup battery;
- and
- b) an adaptor sized and configured to be mechanically mountable to the power supply and physically supportable thereby, the adaptor having an input port plug connectable to the power supply, an output port plug connectable to the wall transformer, and an input/output port plug connectable to the backup battery, the adaptor having circuitry connecting the output and input/output ports, and isolation circuitry for isolating the power supply from the output and input/output ports when a power supply failure occurs.
A battery backup device for powering wall-mounted transformer connectable to a power source and an electrical appliance, the battery backup device comprising:
- a) an input/output port connectable to the wall transformer;
- b) a backup battery in electrical communication with the input/output port, operative to supply power to the transformer when power to the transformer is interrupted;
- and
- c) a plug extendable from the input/output port, operative to connect the input/output port to the wall transformer and to physically support the battery backup pack by mechanical connection to the wall transformer.
