This circuit supplies a load at SO1 when the load at SO2 is powered. The circuit is from a Popular Electronics from the 90s. Diodes and triacs must match the loads.
In this circuit, from a documentation from the 70's, we have the way to control the active cycle of...
This triac phase control circuit uses an integrated circuit not very common today. We found this...
