Re: [TCML] pulse caps for large DRSSTC



But DC -

There are small DRSSTCs, and there are large DRSSTCs.

Saying these caps have "been tested" means nothing unless the test parameters are known.

In the DRSSTC testing that you performed, what were the peak and RMS currents in the primary circuit, and through what range of firing rates?

I have already tested them in DRSSTC service.  They work excellent.  We
checked thermal rise with an infrared camera. No problems after continuous
10 minute runs.

They are comprised of series sections and parallel sections to spread out
the thermal load over a large area.

Dr. Resonance,
If you would be willing to provide to me, free of charge, a sample of each one of these capacitors, I would be willing to verify their applicability to
DRSSTC service.  Failing that, I would be willing to join a group buy,
should some generous soul be willing to set it up (i.e., somebody other than
me).

 I carry high-Q factor heavy duty pulse caps for medium and large size
DRSSTCs.

SSCAP-200 measures 3 3/4" x 5" x 11" and is very conservatively rated 0.8
uF
(800 nF) at 20 kV WVDC.

SSCAP-400 measured 3 3/4" x 5" x 11" and is conservatively rated 1 uF at
20
kV WVDC.

Designed for continuous operation at 12 kV DC in H-bridge configuration.

Contact me off-list for further information.  If someone assembles a
"group
buy" I can provide pricing around $390 per cap.
