AC Phase Control Circuit (LEADING EDGE DIMMER)

Module contains a Triac triggering coupled with zero-cross detector mechanism
for programming the intensity of incandescent lamps, AC LED dimmable bulbs and 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).
Connected LOAD power 500W long-term and 1500W short-term.

Descriptions of pins:

+5V -> device power, DC 5 volts
SYNC -> zero-cross detector output positive impulse (pulse length 200us)
GATE -> triac gate input pin
GND -> ground of low voltage side
AC INPUT -> AC voltage input 110/220
AC LOAD -> Connect your load here !

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