Hello all. I am new here. I've been building coils and other high voltage devices for a few years now. I've got an interesting transformer that I picked up a while back that I would like to try to incorporate into a Tesla coil, though I'm not sure how to go about it, as I usually use teslamap as my calculating program, and I'm nor sure that its designed to accept the parameters associated with this transformer. I though it would be worth a shot to see if you gurus can help me along. The transformer is small, 3"x2 1/4"x2. It is encased in a metal box. the diagram on it indicates 2000 hz at 30v dc on one winding, and 3600 vdc 100 ma dc on the other winding. This seemed a bit odd, but I drove it with 24 vdc, a power transistor, and used my function generator to switch the base, and sure enough, it makes an arc that looks much like a large nst, firey yellow hot. I'd say its comparable looking to an arc from a 9kv 30ma nst, though I suppose it would have been more impressive with the rated 30 volts in. So a few questions...if the one winding says the output is 3600 vdc, what is the ac power out? I'm assuming that the rating is like the old plate transformers whereas they rated them as what they would be if you rectified them. I don;t believe it has a rectifier internal. Second, how would I enter the parameters into teslamap? Would I just enter 30 volts for the input voltage and 200hz as the frequency? Does this seem like a workable hv supply for a coil? The output looks ample. Nothing like what you get from an electronic sign transformer. This is much hotter. Thanks for any input you can provide.
