MaTouch 1.28” ToolSets are series of ESP32-based products mainly consist of MaTouch 1.28” controller and kinds of functional expansion such as Dimmer/ Relay Controller/ Motor Driver, etc.

AC dimmer controls the voltage of alternating current (AC) to adjust the brightness of lights or the speed of motors.  Normally it use phase-cut dimming to control the amount of power delivered to a load. They are often used in homes and businesses to conserve energy and to control the lighting environment

MaTouch 1.28” ToolSets are series of ESP32-based products mainly consist of MaTouch 1.28” controller and kinds of functional expansion such as Dimmer/ Relay Controller/ Motor Driver, etc. It’s designed as tools to control/drive these actuators directly while also keep open hardware/software, which make it possible for users’ remaking and integration to other field projects.

This MaTouch 1.28” ToolSets_AC Dimmer chopper circuit based on Triac BT139, and zero-cross detection circuit, it detects the zero-cross points and then the Triac controlled to chop the AC. Besides, to avoid the problem of AC can not be totally shunted off with Triac, a relay is implemented to make the AC totally On/Off. On-board AC/DC module implemented, so no external power supply needed, suitable for field applications.

This MaTouch 1.28” ToolSets_AC Dimmer Features:

- Input Voltage: AC100 to AC240V,50HZ~60Hz

- Output: AC100 to AC240V，0%~100%

- Max Load:10A 240VAC

- On board AC-DC Module: [email protected]

- Operation Temperature:-20℃ to +70℃
