The standby power-off power strip is low in components number, low in cost, simple and reliable in circuits, convenient, practical, trouble-saving, free of remembering, safe, and energy-saving, and is applicable to single electric appliance or a plurality of electric appliances, such as computers, multimedia, televisions, and home theatre systems.
Description
Technical field:
The invention belongs to field of electric control, relate to a kind of tester in power-down state row seat of treating.
Background technology:
When 1. people make electrical appliance, often forget power cutoff, or the remote-control closedown standby, all can waste electric energy, be unfavorable for the electrical equipment maintenance, influence appliance life, even lead to a disaster.There are power consumption and standby safety problem.
Power consumption during 2. for the elimination electric appliance standby is avoided long-time energising, needs unplugg after most electrical equipment use up, and cut off AC power, and frequent plug bothers not only, more aggravates loose contact, damages plugs and sockets, and influence is used.
3. existing energy-saving control circuit is mostly complicated, job insecurity, and cost is high, and it is difficult to safeguard.
Summary of the invention:
The object of the invention is to provide a kind of energy-conservation row's seat of automatic AC shutoff, is energy-saving control circuit; Detect the size variation of the electric current of master control output electric appliance load, the electrical equipment shutdown or the standby of master control output, output are carried out Energy Saving Control during less than the power set, cut off whole power supplys automatically.Realize control master control electrical equipment one machine, reach the time-delay of the controlled electrical equipment series of master control electrical equipment device power supply (DPS) and all turn-off purpose that zero-power is energy-conservation.Be fit to single electrical equipment or a plurality of relevant electric appliance series use, like computer, multimedia, electrical equipment such as TV, home audio-visual system use.
Treat tester in power-down state row seat, it is characterized in that, by starting button, system power supply, delay circuit, relay circuit, detection line, amplification comparison control circuit, indicator light, a master control output and controlled output composition.
