Abstract

A multi-socket power extension source includes a power inlet port, and power outlets coupled to the power inlet port through switches. The multi-socket power extension source includes a controller configured to control the switches. The controller is configured to repetitively determine if an estimate of a total current through the power inlet port exceeds a prescribed current limit. When the estimated total current exceeds the prescribed current limit, the controller is configured to identify the outlet having the largest current increase and turn off the switch coupled to that outlet. The controller is further configured to reconnect the surge outlet, when an updated estimated total current is less than the prescribed current limit by at least the current of the surge outlet, or after a prescribed reconnect time period. The multi-socket power extension source may be coupled to a secondary multi-socket power extension source in an expansion configuration.
