README
README.mdtriac-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

Questions
How big is the Ssr PCB?
It measures 99.1 × 76.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ssr use?
39 parts, built around the LTV-814 and MOC3052M. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Ssr KiCad files?
From the Miceuz/triac-bloc repository on GitHub, at the commit this page was made from: the board is ssr.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ssr design in my own project?
Its repository states no licence, so its author keeps all rights: ask Miceuz before reusing the design.
