Smart automatic standby power cut-off receptacle

Smart standby power car end according to the invention the outlet is by calculating the average value of the amount of electricity that is measured during a predetermined time when the switching unit on (ON) to a primary and, based thereon, and setting the electricity quantity reference value for the standby power is determined, and further 2 by firstly, switching unit off (oFF) only when the electric charge motion values ​​measured during a predetermined time when determining the standby power is not large to proceed than the reference value, it was able to block to determine more accurately and safely standby power than the existing, thus providing a failure, the benefits that can be significantly prevented by shortening the life of the appliances connected to the load. In addition, the smart standby power car according to the invention only outlet provides an effect that can be further converted by the switching unit off when, additionally a current measuring unit and a control unit to the sleep mode, to reduce unnecessary power of the air outlet circuit itself. Furthermore the invention in a smart standby power car according stage outlet is further provided by the effect of further organically combine the EMC filter side SMPS, reducing the electromagnetic wave of its own internal circuitry effectively.
