AC Phase Control Circuit (Dimming Circuit)
Module contains two Triacs with zero-cross detector for programming the intensity of incandescent lamps, AC LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller.
Working AC voltage 80...240 VAC.
Auto detect 50Hz or 60Hz.
Zero-Cross detection (with zero/cross output pin SYNC).
Compatible with any ARDUINO, RASPBERRY boards.
Low voltage side and high voltage side is completely isolated.
Dimensions of the PCB 90mm x 60mm.
Four mounting holes diameter 3.2mm.
Connected LOAD power for each channel 5A.
NOT appropriate to change the brightness of fluorescent lamps !!!
Control dimming level via FIRING ANGLE method !
Warning: This project deals with AC electricity which is dangerous if you don’t know how to treat it safely. You must treat electricity with caution!
