Description
The utility model relates to a kind of electronic delay control device, and its purposes is to control the time-delay closing of motor, ventilating fan, illuminating lamp and the fluorescent lamp in some place, to reach the purpose of economizing on electricity or automatically shutting down the electrical appliance power supply.
(patent No. 90206530.0 notification number CN2076728U) its device for power switching adopts unidirectional thyristor to be connected in parallel on the control mode of rectifier bridge DC side in existing background technology at present, when if load in use is perception (as fluorescent lamp, fan etc.), delay switch can out-of-control phenomenon occur and can not turn-off, its reason is that the freewheel current of inductive load can not be turn-offed unidirectional thyristor naturally when current over-zero, and be in opening state always, therefore this class delay switch scope of application is restricted, and versatility is not strong.
The purpose of this utility model provides a kind of multifunctional electronic delay switch that all can normally move under resistive or inductive load condition, its characteristics are that this device can be used to control various inductive loads, have expanded range of application; Owing to be provided with and have synchronous startup terminal, when special requirement, can apply a control voltage from the outside to this terminal, make it to become remote-controlled switch, as long as the voltage that is applied on the terminal does not excise, this switch just keeps on-state always, after the excision of the voltage on the terminal, switch turn-offs after delaying time; This is to being equipped with the illuminating lamp of delay switch control in the floor, when be in an emergency night, as long as add voltage on control bus, the illuminating lamp of full floor can be lighted simultaneously, need not open one by one in the dark, time-delay a period of time does not turn-off again after can not occurring opening simultaneously yet.
