Re: [CAD_CAM_EDM_DRO] Voltage recommendation for slosyn kml063f07

Hi Chris,

Funny you should mention KML063F07's! I just got four! I don't have
any "experience" with them yet. Are you in Sunnyvale, by chance? Your
info matches what I've found. What I was also looking for is the LIST
price.

I'm planning on using a 28V, 6A xfmr for mine. This gives 37-40V (I
also have input taps to play with. A 6A rating should drive 3 or 4
motors fine. I will also put in a 2nd transformer, so that I can go up
to 75-80V at a later date.

A good cheap supply is a 24V 6-8A regulated supply. Just connect right
at the cap, and get a good 37V out of them! Often you can find "bad"
supplies, that have a blown regulator, but a perfectly GOOD bridge, cap
and transformer.
