Electrical energy saving device i.e. power strip, for e.g. micro-computer, has decision taking unit to maintain on state as long as consumed power is higher than threshold, and turns off apparatuses when power is lesser than threshold

摘要

The device has a measurement unit providing information representative of power consumed by a functional group of external apparatuses. A push-button (11), control unit (12) and an infrared telecommand signal receiver (13) control an operating voltage of the apparatuses. A hard-core maintaining unit maintains on state of the apparatuses for a preset time. A decision taking unit maintains the on state of the apparatuses as long as consumed power is higher than a preset threshold, and automatically turns off the apparatuses when the consumed power is lesser than the threshold.
