4 Channel Ac Programmable SSR Light Dimmer Module Controller Board Arduino Raspberry Compatible 50/60hz …

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!
