8 Channel Digital Light Dimmer 3.0 version
working AC voltage range 80...240VAC and 2A current per channel
Module contains 8 Triacs with zero-cross detector for programming the intensity
of incandescent lamps, heating elements, AC LED dimmable bulbs or fan speed controlled through a micro-controller.
Working AC voltage 80v 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 131mm x 91mm (5.16inch x 3.58inch). Four mounting holes diameter 3.2mm (0.13inch).
Connected LOAD current for each channel 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 my market!
Dimming control 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!
