Abstract
An apparatus for controlling a power supply includes a plug, a plurality of electrical outlets, a communication interface, an encoder, and a selecting circuit. The selecting circuit is electrically coupled between the electrical outlets and the plug. The encoder receives a control signal via the communication interface and outputs a selecting signal to the selecting circuit. The selecting circuit controls connections between the electrical outlets and the plug via the selecting signal.
