MAINS Power Dimmer / Switch Module project by Tracker J:
Now it’s about time to talk also about what many of you has asked for: DIMMING!
It’s a total different story, little bit complicated but, as you will see, not so hard to understand.
There are several types of dimmers generally available. These are used for resistive, and inductive loads, such as incandescent,cold cathode and low voltage (inductive) lamp sources. Note that not all electronic transformers used for low voltage lamps are suitable for dimming by Triac or Thyristors dimmers. In case of Thyristors you need 2 of them as Thyristor is a Unidirectional device and because AC power flows in both directions!
