Patent ID: 8897924

Claim:
A method for providing power management to a power source for providing input current to a plurality of power outlets and a plurality of other loads, comprising: measuring, in an unrestricted power mode, an input current provided by the power source to the loads and the power outlets across each power phase of the power source; determining whether the measured input current is less than a first set current value; repeating said measuring the input current, in the unrestricted power mode, in response to said determining; deciding whether the measured input current is greater than the first set current value and less than a second set current value that is greater than the first set current value; entering a first power limiting mode in response to said deciding, the first power limiting mode including: disabling each unused power outlet; measuring a first resultant input current provided to the loads and the remaining power outlets across each power phase of the power source; and enabling each of the disabled power outlets and exiting the first power limiting mode if the first resultant input current remains less than a first release current value during a first time interval that is greater than a first release timer value, the first release current value being less than the first set current value.
