Energy-saving controller for high-power electrical appliances

Abstract

The invention discloses an electricity-saving controller for a high-power electrical appliance. The electricity-saving controller is characterized by consisting of a starting circuit, a system power supply, a power detection circuit, a delay control circuit, a relay circuit, a master control output end and a controlled output end. The control circuit is simple; when the electrical appliance at the master control output end is shutdown or standby and the output is less than preset power, the energy-saving control is performed and all power supplies are cut off automatically. The zero power consumption and the energy saving are achieved. When one power supply is started, all power supplies are started; when one power supply is shutdown, all power supplies are shut down; therefore, the troubles in up-plugging power supply plugs or turning off switches on sockets are solved after each use. The electricity-saving controller for the high-power electrical appliance is applicable to the single electrical appliance or a plurality of relative series of appliances; a power metering circuit with an electronic power meter is applicable to load detection of various performances and is accurate and reliable; the control circuit has the advantages of low power consumption, few elements, low cost, convenience and practicability, safety and energy-saving, and reduction of troubles and memo.

Description

[0001] Technical field: [0002] The invention belongs to the field of electronic control and relates to an energy-saving control circuit. [0003] Background technique: [0004] 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. [0005] 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. [0006] ③ Most of the existing energy-saving controllers have complex circuits, unstable work, high...
