Energy saving control switch

Abstract

The invention discloses an energy-saving control switch, which is characterized by consisting of a switch with a relay, a system power supply, a time delay circuit, a relay control circuit, a power detection circuit, a master control output end and a controlled output end. The control circuit is simple, and when an electrical appliance at the master control output end is turned off or standby, and the output of the electrical appliance is lower than set power, the energy-saving control switch performs energy-saving control, and automatically turns off all power supplies. Zero-power consumption energy saving can be realized, and the energy-saving control switch can turns on / off all the power supplies at the same time. The trouble of unplugging a power plug or turning off a switch on a socket after the electrical appliance is used can be eliminated. The energy-saving control switch is applicable to a single electrical appliance or a plurality of related series of electrical appliances. A power measurement circuit of an electronic energy meter is utilized, and the energy-saving control switch is suitable for the load detection of various kinds of performance, is accurate, reliable, low in control circuit power consumption, low in cost, convenient, practical, safe and energy-saving, comprises a few components, and has a memo function.

Description

Technical field: [0001] The invention belongs to the field of electronic control and relates to an energy-saving control circuit. Background technique: [0002] ①When people use electrical appliances, they often forget to turn off the power supply, or turn it off by remote control for standby, which will waste electric energy, which is not conducive to the maintenance of electrical appliances, affects the life of electrical appliances, and even leads to accidents. There are energy consumption and standby security issues. [0003] ②In order to eliminate the power consumption of electrical appliances in standby and avoid long-term power on, most electrical appliances need to be unplugged after use to cut off the AC power supply. Frequent plugging and unplugging is not only troublesome, but also aggravates poor contact, damages plugs and sockets, and affects use. [0004] ③ Most of the existing energy-saving controllers have complex circuits, unstable work, high cost and diffi...
