scr high power alarm driver circuit design


Posted on Feb 5, 2014

A very simple high power alarm driver electronic project can be designed using this circuit diagram. This high power alarm driver electronic project is based on low power SCR which trigger a high power SCR. When a switch is opening (S2, S3, S4) or closing (S5, S6, S7), either SCR1 or SCR2 triggers. This triggers SCR3 via D1, D2, and R5. When t
