PWM Control Module Power Single Chip Microcomputer Controller Board AC220V YYAC3S
Description
1、Safe Working: Adopts original thyristor and ensures completed isolated input and output optocouplers can work safely under weak current. 2、For Control: PWM output through the IO port on single chip microcomputer can adjust the duty ratio and change the 220V AC voltage to achieve the purpose of dimming speed and power adjustment etc. 3、Output Power: Controllable load within the range of 220V 3A or 660W and the output under certain load can achieve normal voltage regulation. 4、PWM Input: When PWM directly inputs 0V low level the output is 0V and when PWM directly inputs 5V the output is 220V. 5、Application: Connect this control module to lamps or household appliances for dimming speed voltage and temperature control.
