capacitors for water desalinisation
Hi all
I don't know exactly where to post this - maybe the power supplies section would be better. Moderators, feel free to move the thread!
Recently I have got some capacitors made by Ducati, rated 100muF, 750Vdc (530VAC), 80 Imax. They are 25cm/10" long (without considering the binding posts) and 7,5cm/3" in diameter. Pretty big, actually. The guy who sold them to mee told me he took them out of a water desalinisation station, that was built for a boat, but never used (so capacitors are new). I am sure they are reliable and that they will work in tubeamps power supplies, but I am just curious if anyone also uses, or tested, those capacitors and how they compare to others!?
Many thanks for the attention
Erik

Lookie here:

I'm just guessing that they are oil motor runs, but they do seem kinda big for 100µF. Checkout the .pdf documentation. The 530VAC might be 1000 hour life.
Anyone know where to get Duck caps? I would like a few, to paint red of course.

Hi Ethermion and EC8010
Thanks for the replies and EC8010 for moving the thread! I already had a look at the ducati website, but could not find this kind of capacitor over there. It has got screw terminals (M10), not the faston ones like the motor caps.
Yes, they are big! I will make the PS on a separate chassis - I actually have time to do it right now, but with the 30+ degrees celsius over here I much prefer the garden with a beer than the hobby room with a soldering iron and power hungry HOT tubes!

Likewise, the thought of going into the workshop and running a 500W motor (drill), or 700W motor (lathe or mill) just fills me with horror. I've just had an ice cream...
