This SCR is so important in Stans Technology, I am dedicating a place in my very on Category just for this device.
An SCR, or Silicon Controlled Rectifier, is a semiconductor, or integrated circuit (IC), that allows the control of current using a small current. Basically, it is a simple direct current (DC) light switch
I think Stan may have used this device to Clip Off the Peaks of the voltage fields. I am in the earliest understandment in understanding this device. Further research of this device, and Such will be updated momentarily.
