WebJul 14, 2008 · This input is then translated into an output to the triac. When the triac is being modulated, the LED is turned on to indicate the unit is on. A 1,100-W heating element is being switched by the triac. In countries using 115 Vac, this translates to an rms current of nearly 9 A; therefore, a rather large triac is needed. WebJul 9, 2024 · Abstract. Triac is a three terminal AC switch which is different from the other silicon-controlled rectifiers in the sense that it can conduct in both the directions that is whether the applied ...
