Hi,
I've just uploaded a schematic of a 40V 3A circuit that I put together.
I've thrown in every security measure I could find in the DigiKey manual as
an exercise. The file is in FILES / Power supplies. This link may (or may
not) work:

station%2040V%203A%20steppers.JPG>
Please let me know if I have design flaws, is the fuse rating high enough,
components in series instead of parallel or vice versa, suggestions for
additional security measures, improvements in filtering, etc.
This is my first power supply and I don't want to have problems with it in
the future. I also want to make it as robust as possible. A separate 5V
circuit will power the logic circuitry, this is exclusively for the
steppers.
