Systems and devices for reducing phantom load

摘要

Systems and devices are described herein for reducing a phantom load. The system may include a device for connection to a power source and a transformer (110) or machine, wherein the device is configured to disconnect the transformer or machine from the power source under a predetermined load condition. The device may include a contactor (160), a current detector (130), a timer (140), and a controller (150). Portions of the current detector, timer, or controller may be implemented in a microcontroller.
