Triac Dimmer Schaltung. In scrs it conducts in only one direction but in the case of triac the power can be controlled at both directions. In the last section we saw that a dimmer switch rapidly turns a light circuit on and off to reduce the energy flowing to a light switch.
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. 4 1 out of 5 stars 136. Toggler led dimmer switch for dimmable led halogen and incandescent bulbs single pole or 3 way white the toggler led dimmer provides optimal the toggler led dimmer provides optimal dimming performance of led bulbs.
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.
Here we are using a bt136 triac for ac lamp dimming purpose. This triac based 220v ac motor speed controller circuit is designed for controlling the speed of small household motors like drill machines. The speed of the motor can be controlled by changing the setting of p1. 120v triac dimmer switch in wall led dimmer light switch for 150w dimmable led cfl 600w incandescent halogen bulbs single pole or 3 way screwless wall plate etl listed white.
