MAKERFABS-AC-Dimmer

Product description

The Makerfabs Home Assistant AC Dimmer uses a chopper circuit built around a BT139 TRIAC and a zero-cross detection circuit. It detects each zero-crossing and then controls the TRIAC to chop the AC waveform for dimming. In addition, because a TRIAC cannot fully disconnect the AC on its own, a relay is included to provide complete on/off isolation.

• On board AC-DC, No external power supply needed;

• On Board Relay to totally shut down current leakage;

• ESP32 for Home assistant/ ESPhone;

• STM32G030F6P6 , for AC choppping;

• Suitable for AC 110V~230V, Any frequency;

• Max Load: 2KW;

It can be purchased from Makerfabs.
