Are U trying in the hardware or on the Proteus software ? If on Proteus it may not work .Change the triac to any one having library of TECCOR it will work .Don't take the generic one as it will not work in the simulation.In hardware one must know that Triacs need more triggering current as compared to a SCR so design the same accordingly
Hi, I'm fighting with a strange problem, I use a MOC 3043 to trigger a triac bud it wont work and I use the scheme of the proposition in the data sheet for the 230 V version.
I simply want to switch a normal lamp of 40 W.
I used the same copler for 2 thyristors back to back and this was working. I used only one MOC3043 like in the scheme in the data sheet ??
Why You use two MOC3043's ? For the triac version I thing I must change the serie resistor value ? Can You help ?
Hi, I'm fighting with a strange problem, I use a MOC 3143 to trigger a triac bud it wont work and I use the scheme of the proposition in the data sheet for the 230 V version.

If I send pulses on the digital line (PWM), will this circuit become a dimmer?
If so, what would be the frequency range?
