该电路如下图所示,它由电源电路、声控电路、光控电路和延时电路四部分组成。 电路原理如下:被控制的对象是普通灯泡(适合100W以下的灯泡),220V交流电与灯泡串联后接整流全桥,经整流全桥后得到脉动直流电,提供给晶闸管vs和控制电路使用。由于脉动直流电压在200V左右则通过R1(150k)降压后提供给控制电路使用,VD1在此具...

This invention relates to a time delay switch for reversing mechanism, and more particularly to an improved switch for reversing a motor effecting reciprocation of heavy movable bodies such as channels used in carbon manufacturing plants. One feature of this invention is that it provides an...收藏...
An improved saturation detector monitors each transistor to determine when it is in saturation and generates a feedback signal which is combined with the input signal to generate the appropriate time delay needed to improve the switching time of the transistor....
1、不改变布线,不改变现有墙壁开关外观。 通常墙壁开关只将火线引入墙壁开关暗盒内,而许多排气扇延时开关都需要同时接入零线和火线,这给改造带来诸多困难,尤其在浴霸与排气扇合为一体的情况下。如果采用本设计,则不改变原来的布线,而且现有墙壁开关外形没有任何改变。
