I,ve posted something similar before, but did not really get a solution. I want to test a thyristor, the puck type that is used in a machine where 600A or so flow through it. I have a whole lot that need a test rig to be made. I want to pass throgh the minimum voltage I can. The SCRs are rated at 1300A and have turn on currents of 200mA and 3V max. Would it be fine to test these using as little as 24V or even 12V? Just to check they are indeed turning on correctly? I have attached a pdf as example, I cant find the exact one. Would a circuit like the one I atttached work ok?
