Abstract
Abstract There is a provided a system of one or more uninterrupted power supply (UPS) units, each UPS unit having distributed processing system and a network interface for interfacing with a local area network, the network providing a communication between the one or more UPS devices and also to loads powered by such UPS devices. In one embodiment having a plurality of UPSs, one of the UPSs is a main upstream UPS which is in communication with each down stream UPS to which it supplies supplemental power and which in turn supply power to respective loads. In another embodiment the UPS supplies power to a plurality of prioritized loads, and is in communication with each such load over a network and also controls power distribution to each such load through a power distribution module (PDM).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
144 words
A system comprising an uninterrupted power supply (UPS), a plurality of loads having predetermined priorities for maintenance of power thereto, a network for transmitting data to and from each of said loads and said UPS, and bar connection means for connecting power separately from said UPS to each of said loads, said UPS having network interface means for interfacing with said network, said network interface means further comprising processor means for processing data and control signal generating means for generating control signals for controlling connection of power to each of said loads, said processor means comprising first means for generating messages to each of said loads wherein said messages concern time remaining for receipt of power by such load, and second means for generating shutdown signals and connecting said shutdown signals to said control signal generating means for controlling prioritized shutdown of said loads.
Claim 2
Independent Claim
144 words
A system comprising an uninterrupted power supply (UPS), a plurality of loads having predetermined priorities for maintenance of power thereto, a network for transmitting data to and from each of said loads and said UPS, and bar connection means for connecting power separately from said UPS to each of said loads, said UPS having network interface means for interfacing with said network, said network interface means further comprising processor means for processing data and control signal generating means for generating control signals for controlling connection of power to each of said loads, said processor means comprising first means for generating messages to each of said loads wherein said messages concern time remaining for receipt of power by such load, and second means for generating shutdown signals and connecting said shutdown signals to said control signal generating means for controlling prioritized shutdown of said loads.
Claim 3
Dependent Claim
27 words
