Triac Schaltung Motor. Flh731 flh491 bf324 impulsgenerator sägezahngenerator. With switch sw1 open no current flows into the gate of the triac and the lamp is therefore off.

It can conduct current in either direction between its mt1 and mt2 terminals and can thus be used to directly control ac power. When the timer is on the circuit will close and the optoisolator will signal the 40 amps triac to allow the ac current and the heater will be switched on. Dabei wird ausgenutzt dass thyristoren und triacs einen zehnfach höheren.
A triac is a three terminal mt1 gate and mt2 solid state thyristor that uses the alternative symbols in figure 1 and acts like a pair of scrs wired in inverse parallel and controlled via a single gate terminal.
Triac is often used as a means of light dimming. Triarc electric supply is your lighting power distribution and lighting controls specialist. Triac is often used as a means of light dimming. The circuit above shows a simple dc triggered triac power switching circuit.
