The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. The input can be analog signal from microcontroller working at 0-3V or 0-5V which is isolated with the use of opto-couplers.
The board can be used in applications where dimming of 110-220V AC power is required like dimming of bulb or fan. It supports up to 16A . But such currents will require a proper cooling.
