2CH AC LED Light Dimmer Module Controller Board For Arduino and Raspberry Smart Home


Main Features:
  • AC Light Dimmer Module Controller Board ARDUINO RASPBERRY Compatible 50/60Hz
  • Connected LOAD power for each channel 5A.
  • Compatible with any ARDUINO, RASPBERRY boards.
  • Auto detect 50Hz or 60Hz. / Working voltage from 110v to 240v.
  • AC Phase Control Circuit (Dimming Circuit) / Home Automation, School Projects, Work Related Projects

AC Phase Control Circuit (Dimming Circuit) Module contains two Triacs with zero-cross detector for programming the intensity of incandescent lamps, AC LED dimmable bulbs, heating elements or fan speed controlled through a micro-controller.
Working AC voltage 80...240 VAC.
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 90mm x 60mm.
Four mounting holes diameter 3.2mm.
Connected LOAD power for each channel 5A.
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!
