  • Patent number: 5534734
    Abstract: A power shedding device controls the application of power from an uninterruptible power supply (UPS). It includes circuitry for detecting an alarm signal indicative of a condition requiring the rationing of power from the UPS, and a plurality of power outlets for connection to a plurality of loads such as computers, printers, and other associated devices. A microprocessor controls the application of power to each power outlet pursuant to program control such that the application of power to a first power output is independent of the application of power to a second power output. Manually operable switches are provides for presetting shedding profiles for the power outlets during a shutdown procedure. The processor is responsive to receipt of an alarm signal to shed each power output in accordance with its corresponding manually preset shedding profile. A low UPS battery alarm results in an override of the shedding profiles if the remaining time to shutdown for an outlet exceeds a predetermined limit.
