It could be a bit larger than that, but I remember that it was possible
for me to carry it, so it couldn't have been much more than 100lbs at
most. I vividly remember the rating of 4kV at 1.5A. It originally had
a nice 30A Variac sitting in front of it to change its output voltage.
It could have been up to about 12" on a side. It's been a while since
I've had it.
Also, I'm pretty sure it wasn't designed for 100% duty cycle for its
application (NM imaging), so it's likely that they used under-sized
condutors.
IIRC, it was supposed to run off of a 208 or 240V input, not off of
110V, as well. So, we're down to 25-30A input. :)

Soudns rather small to me. 4kV at 1.5A is 6kVA (!). That means it's
going to draw nearly 60A from a 110V supply. Are you sure that's the
rating? On 4/28/05, Patrick Finnegan <pat at

Unfortunately, I don't have a picture of it, and I got rid of it a
while ago when moving offices. It was a black cube roughly 8" on a
side, and weighed in at 80lbs or so. Heh. About a year and a half ago, I pulled the
transformer out
of an NMI power supply. 4kV at 1.5A rating.
That sucker could blow fuses really well. ;)
Holy moley!! I can imagine... :-)
Could you please post some pics of this monster? I haven't seen
one rated this much before...
