Abstract
The invention relates to an energy-saving control circuit capable of automatically turning off power supplies, which is characterized in that all power supplies are automatically turned off when an electrical appliance at the master control output end is powered off or in standby and outputs power lower than the set power so as to realize zero power consumption and energy conservation. Through utilizing a power measuring circuit of an electronic electric energy meter, the energy-saving control circuit is suitable for detecting loads with various properties and is precise and reliable. The trouble that a power plug is pulled out or a switch on a socket is turned off every time after the electrical appliance is used is saved.
