AC Phase Control Circuit (Dimming Circuit)

Leading Edge AC Dimmer for inductive and resistive loads

now available wiring diagramm for Raspberry boards 

Module contains a Triac triggering coupled with zero-cross detector mechanism
for programming the intensity of incandescent lamps, AC LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller.
 

Working voltage from 110v to 240v.
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 50mm x 60mm.

Four mounting holes diameter 3.2mm.

Connected LOAD current 2A long-term and 5A short-term.

Not for controlling via PWM signal !

NOT appropriate to change the brightness of  fluorescent lamps !!!

For inductive load controlling must be connected RC snubber, search it in my store!!!

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!
