SCR Triggering Circuit

Product Code : JA-PET-1424

The SCR triggering circuit trainer shows how the TCA-785 signal conditioner and pulse generator IC fires an SCR with controlled gate pulses. Students change the reference voltage and follow the change in firing angle, working with an opto-coupler, a 100 V/1 A SCR and a BC-107 transistor on the panel (SKU JA-PET-1424).
