Automatic variable power outlet for energy saving power source

摘要

A variable power device in a form of a power strip includes a plurality of power outlets for powering electrical devices connected thereto. A current sensing circuit is electrically coupled to each power outlet and senses current flowing through the power outlet and drawn by an electrical device connected to the outlet. A power control circuit selectively provides one of a standby mode power signal and an active mode power signal to a respective power outlet in response to the feedback signal from the current sensing circuit associated with the power outlet.
