nice unstable lightsaber and sound lol,,,, your title says 3kw 9kva ? but if you say you measured the output from the trans connected in series and found it to be 6kv and 1.5 A then your power is 9kw not 3 kw and 9kv? where did you hook the caps? cant you give schematic details? and I tought mots pull more amps than 1.5?

@jmartis2 Really? Cos I had one, it drew around 10 amps when an arc was drawn, it never blew a fuse. Thats now had the secondary chopped and rewound for 12VDC. Getting around 50 amps + from it.

Be careful!

are the 4 caps in series, parallal or series parallel?

Did you put the MOT's in series or parallel?

@quinnmiller1997 In series.

Dual MOTs it says in the description. So where did you get these 4.5kVA transformers? At most, its around 1800 - 2000 VA.

@io504 I measured around 3 kV on the secondaries with the output shorted, probably the result of some resonant rise. The current is around 1.5 amps, with two transformers this is 6kV * 1.5A. The measurement of the voltage might have been a little off, in any case it is over 6 kVA.

@jmartis2 Have you measured the amperage? And congrats on finding such beastly MOTs then, where'd you get them?
io504 3 months ago
@io504 Yes I have measured the current. They are pretty standard MOTs. FYI a normal MOT draws around 20-25 amps from 230 volts shorted, that is around 5 kVA.
