Triac Dimmer Schaltung. The speed of the motor can be controlled by changing the setting of p1. Michael neary is a product line manager.
This simple triac speed control circuit is suitable for not only ac motor speed control but for lamp dimmers and electrical heater control and in fact is very similar to a triac light dimmer used in many homes. Like a transistor a triac is made up of different layers of semiconductor material. 99 7 99 100 g 16 88 16 88.
The moc3021 has actually total of 6 pins but pin number 3 and pin number 5 are not used.
Pin number 1 is the anode and pin number 2 is the cathode as per the datasheet a 330 resistor is connected in series with the anode of the ir led. In scrs it conducts in only one direction but in the case of triac the power can be controlled at both directions. 99 7 99 100 g 16 88 16 88. I have a question about a dimmer circuit with a triac.
