230V AC dimmer

Advertisements

Description:

A reliable and efficient all-around performer. I bought the kit because it didn’t cost me much more than the components were worth and I also got a nice professional-made PCB inside.

As you can see, this is a tried-and-true diac & triac combination that offers both simplicity and high performance. With a load up to 3.5A, the power rating is 750W at 230V. A heat sink on the triac is a must!

Note: for 110V operation, add a 220k resistor in parallel with the 470k pot. No other modification is necessary. But since the maximum allowed current is still 3.5A, the highest possible power output will drop to 380W.
