Nice answer, but But still unclear. Why not buy a dimmer switch?
Post as a guest Name. Use good wiring practices.
Your controller circuit rif630b need to detect the zero-crossing point and trigger the triac after the required delay. You are taking on an ambitious project given your current knowledge. For your dimming application you need non zero-cross so that you can switch on at any point in the cycle.

I need to know how to control high AC voltage with low DC Sign up or log in Sign up using Google. Look up mains zero-cross detection circuits. If you want to switch VAC then use a relay. With this scheme, you cannot control an inductive load unless you come up with some way to deal with the inductive kickback. Email Required, but never shown.
Consider developing your system using a low voltage transformer supply 12 to 50 V AC where a short circuit with your probes or hands won’t be lethal. Only if you want a small explosion! Sign up using Facebook. SSRs come in two flavours – zero-cross and non zero-cross.
I iirf630b want to use relay dahasheet I need dimming Because I wana create one Home Questions Tags Users Unanswered.
I will also need zero cross optoisolator to detect zero crossing on VAC, is that true? Which triac is good for VAC? You are working with main voltages. Tahmid 1 7. And if it is, which optoisolator I can use on VAC? Vladimir Djukic 1 9. Choose a triac to match your line voltage and the igf630b current.
