AC Phase Control Circuit (Dimming Circuit) Leading Edge Dimmer for resistive and inductive loads Module contains four Triacs with zero-cross detector for programming the intensity of incandescent lamps, LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller. Working AC voltage from 80v to 240v. Auto detect 50Hz or 60Hz. Zero-Cross detection (with zero/cross output pin SYNC). Compatible with any MCU or ARDUINO and RASPBERRY boards. Low voltage side and high voltage side is completely isolated. Dimensions of the PCB 110mm x 60mm. Four mounting holes diameter 3.2mm. Connected LOAD power for each channel 500W long-term and 1000W short-term. 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!
