Found on a 1965 Radio Electronics, this circuit fires a signal xenon lamp applied to the SCR from an external trigger. The pulse transformer generates high voltage for flash triggering.
We found this relaxation circuit with diac in an opto-electronic documentation with diac....
Found in American documentation from the 90s, this circuit can be implemented with modern...
In the figure we have a very simple trigger circuit for an SCR that powers a 12 V lamp whose...
