Patent ID: 7514815

Claim:
A system for controlling power to a plurality of loads from a plurality of power sources, wherein at least one of the plurality of power sources is a primary power source and at least one of the power sources is a back-up power source, the system comprising: a first input to receive power from the primary power source; a second input to receive power from the back-up power source; a plurality of outputs to provide output power to the plurality of loads; a plurality of controllable switches each coupled to the first input, the second input and at least one of the plurality of outputs; and a controller adapted to control the plurality of controllable switches, wherein the controller is configured to detect a loss of primary power and to control the plurality of controllable switches based on a categorization of the plurality of loads as delayable or non-delayable, and wherein the controller is configured to selectively turn on and off delayable loads based on available power from the back-up power source, and wherein the controller is programmable to set a maximum delay time for each of the delayable loads.
