Re: Sanity Check on Power Supply Capacitor Size

oP'S !! MY MISTAKE.

wrong !!, your power supply will be at 25 volts, you need 35 volt
capacitors.

56,000µF P10017-ND $13.77


There are a couple others, 39k and 47k on that page in the catalogue.
slighly lessor in price. any one would work.

check the total of the motors and re-run the calculations to see what
you come up with.

I have a pretty ugly spreadsheet for sizing the capacitors.

If there is any interest, I can send it, or post it in the files
section. Anyone wanna make it look spiffy, let me know.
