目前在我国现有的遥控型彩电中,绝大多数均不具有对交流电源的遥控关机功能,这对使用者有所不便。其实加装交流关机功能是一件很容易做的事,其元件仅仅需要一只12V单组触点的直流继电器,基本上是一改即成,现将改装原理及方法介绍如下: 所谓遥控交流电源关机,只是在原来彩电的手动电源开关上,并联一组继电器触点JK。而将电源开关锁定型改成轻触型,其电路工作原理如图1所示。
Currently in our country’s existing remote-controlled color TV sets, the vast majority do not have the remote power off AC power function, which inconvenience to the user. In fact, the installation of AC power off function is a very easy thing to do, its components only need a 12V single-group contact DC relay is basically changed Serve, Now the modified principles and methods are described below: The so-called remote control exchange Power off, but in the original color TV manual power switch, a parallel set of relay contacts JK. The power switch lock type into a touch type, the circuit works as shown in Figure 1.
