AC Phase Control Circuit (Dimming Circuit)
Leading Edge AC Light Dimmer V3.0
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, 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 50mm (1.97inch x 1.97inch).
Four mounting holes diameter 3.2mm (0.13inch).
The distance between mounting holes is 42.7mm.Connected LOAD current 1A long-term and 5A short-term..
If you want connect LOAD power more than 250W, connect triac to heatsink.
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!!!
