I’m looking for some guidance on a circuit.
I found a circuit that would suit me down to the ground http://www.inmojo.com/store/inmojo-market/item/digital-ac-dimmer-module/
. But unfortunately they are unavailable to purchase at the moment, so I (hopefully) am going to try recreate the circuit, as the schematic is supplied. See image:
Now I know working with AC is dangerous, and I will take all necessary steps to be safe.
It says that this circuit works with 120v and 240v, so that’s fine. I’m just having a hard time finding exact parts. I already have an moc3021 and the triac, so the dimmer side is sorted. I can get hold of a 4n25. It’s just the bridge rectifier i am uncertain of, if anyone can suggest an alternative, also, any ideas of what wattage resistors should be used?
Any help is greatly appreciated.
