Triac Dimmer Schaltung. The central element in this switching circuit is a triode alternating current switch or triac. Analog mixed signal design.
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. 300w ac light dimmer mod to 500w. Input supply jerk of triac when power turned on.
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.
Like a transistor a triac is made up of different layers of semiconductor material. 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. The moc3021 has actually total of 6 pins but pin number 3 and pin number 5 are not used. Creating the ideal configuration of led lamps with the triac dimmer has in the past been a challenge but the introduction of new triac dimming led drivers has made this much simpler.
