I'm looking for someone in a country with 120V mains system to do the final tests. If you have experience in AVR programming, drop me a note, I will sell you one for the BOM price
TRIAC BLOC is a high power high voltage switching module that can be used in multiple ways to switch AC mains loads:
TRIAC BLOC is controlled by I2C interface, it also provides low level optoisolated zero crossing and triac fire signals for an easy integration into existing digital system.
A somewhat random list of features:
I've made this module as I needed a high power switching module for refurbished ceramics kilns, also we do a lot of work related to stage lighting, so dimmer functionality came along. More background information is available in this blog post.
WARNING: This product is sold as a kit. While the design complies with safety regulations for minimum allowed creepage distances, it has no official certification. The product involves high voltages that could possibly kill you. Please don't buy it if you are not experienced working with AC mains level voltages.
The board comes with all of the components presoldered except for the output filter choke. You will have to choose an appropriate heat sink if it's needed and solder the triac to its place. The board comes without the main filtering choke. Depending on your load you either don't need (solder a jumper wire instead of it) or you will have to wind one yourself.
