Abstract
The present invention of a power supply and battery back-up system includes an AC/DC power supply and a battery for supplying operating power to a telecommunications system. The battery is connected to the telecommunications system and is designed to supply the telecommunications system with operating power if the power supply fails for some reason. The power supply is designed to output the peak operating power required by the telecommunications system, supplying the telecommunications system with whatever operating power it needs and supplying the difference between the operating power supplied to the telecommunications system and the peak operating power output by the power supply to the battery for charging. In one embodiment, the battery back-up system includes a battery monitoring circuit for monitoring the battery voltage and a relay connected between the battery and the telecommunications system for disconnecting the battery if the battery voltage falls below a pre-set level.
