triac-bloc

A universal power block based on triac. In essence this is a high power solid state relay augmented with some bells and whistles.

Bells and whistles:

• Attiyny44 MCU on board
• I2C interface
• maximum power - 6kW
• zero crossing detection
• controllable via I2C protocol
• phase shift dimmer mode
• linear output power control
• switch at zero-crossing mode
• output filtering for dimmer mode
• snubber network
• “low level” zero-crossing signal output
• “low level” triac trigger signal input
• 4 spare MCU pins available for additional features
• open source hardware and firmware
