We are using AC/DC converters and special DC constanter with 300 V/DC
30 up to 60 Amps for nano or micro perforation machines since more
then 20 years.

There are several companies very well equiped - have a look to
http://www.kfactor.it or http://www.irem.it

Such AC/DC STABLIZED power supplies are to purchase by around 4000 -
6000 bucks by one year guarantee so that it makes not sense to invest
several 10,000 bucks in developments for NEW primary AC switching and
secondary DC regulated units.

Let me know if you need more or specific details - I'm glad to help
and support you.


The only detail that could possibly help me at those kinds of prices is "do
you give free samples ??" :) :)

I makes very little sense to invest that kind of money when I've got less
than $500 into this laser so far, and I dont think its going to cost me more
than about $1000 more to bring it online. I'm not being funded by a
corporation with deep pockets :) In any case, for that kind of money, I
could afford to pump this rod with 808nm laser diode bars and skip the
massive current requirements that the krypton arcs are forcing me to deal
with. ($6,000 times the 3 supplies I need pays for a LOT of laser diode bars
!!)

And I seriously doubt its going to cost me 10K or better to to design my
own -- even if I count my time invested -- I'm pretty close to something
workable now with less than a week invested, and between the folks here and
what I'm finding online, working out the rest of the issues shouldnt take
all that long. And besides -- I get to learn something new in the process !!

So save the commercial hype for someone that doesnt want to be bothered with
