The dormancy unused time must otherwise be introduced into switching off in limited time control within the time in limited time.Through electric circuit inspection control, relay discharges,
Cut off the electricity supply.
E: civil power exceedes when arranging value, and the stabilivolt VD1 conducting of superpressure detection, audion Q2 turns on, Control three
Pole pipe Q1 ends, and relay discharges, and power supply is all off.
With rule: TV is seen in bedroom, the machine of switching off the TV of need not getting up, close Set Top Box, seem during cold day more convenient, before falling asleep,
As RTV remote television arranges sleep timing 30 minutes, the turning device to sleep mode time must otherwise be introduced into switching off in limited time within the time in limited time
Control.After 30 minutes, television set enters holding state, through this energy-conservation socket detection, cuts off the electricity supply, i.e. turns off the electricity of television set
Simultaneously, together with controlled peripheral hardware electrical equipment, such as power supply also controlled shutdown such as Set Top Box, DVBs, this energy-saving socket is electric in source
Source simultaneously turns off, and zero-power is energy-conservation, memorandum.
With the energy-saving controller of overpressure protection Yu switching off in limited time, master control outfan electrical appliance is less than when adjusting power, carries out energy-conservation
Control, automatically cut off all power.When series associated appliance uses, control master control electrical equipment one machine, reach master control electrical equipment and be subject to
The purpose that control electrical equipment series device power supply (DPS) time delay is all off, eliminates electric appliance standby, and zero-power is energy-conservation.When there is civil power superpressure
