Patent ID: 6882943

Claim:
A system for configuring a power supply apparatus to supply a voltage optimized to tolerate a voltage range about a nominal operating voltage of a device, and comprising: a utility voltage test component operable to test and communicate to a comparison component a present utility voltage value; said comparison component operable to compare said present utility voltage value with a present nominal operating voltage value of said device; a configuring component in data communication with said comparison component and responsive to said present utility voltage value falling within an upper half of a first range having a centre point higher than said present nominal operating voltage value and lower than an upper out-of-tolerance voltage value of said device, configuring said power supply apparatus to supply power at a voltage within said first range; and said configuring component further responsive to said present utility voltage value falling within a lower half of a second range having a centre point lower than said present nominal operating voltage value and higher than a lower out-of-tolerance value of said device, configuring said power supply apparatus to supply power at a voltage within said second range.
