The 1650v is what I always seem to find with the output current from 300-700mA. That's how I measured the output, running the primary at 12v and then multiplying it by 10 for 120v primaries or 9.5 for 115v ones.

Mike,
I doubt it because this MOT is substantially larger than the other coils and it has a lot more turns on the secondary. Also, the 4000 V is labeled right on the transformer with the manufacturer's data. Since the manufacturer doesn't know how the end user is going to wire the transformer, they wouldn't put the 4000 V assuming it is going to be driving a voltage doubler or anything else, for that matter.


I'm curious, where did you get the 1650 vac figure? Almost everything I've read on this list and on countless web sites say that the majority of MOT's are 2000 vac and the heavy duty ones 4000 vac. I am going to drive them with my variac set to 10 vac and measure the output from the secondary. Then, I can extrapolate the output at 100 vac on the primary. Anyone have a better idea of determining the secondary voltage on MOT's??
