Theremino OptoTriac V1


A relay from optocoupled 3 KW

This circuit is very similar to a power switch. Can turn on and off large loads, such as furnaces and boilers. And it also works well with inductive loads such as motors, Transformers and large electromagnets.

By means of a photo-coupler “Zero crossing”, the switching times are always at the precise moment of the passage of the zero. Then the commutations are clean, the electromagnetic interference are completely absent and do not develop dangerous voltage extra-.
