I need a 36vdc to 24vdc step down power supply of some sort for a CNC
Servo motor control to test/calibrate my servo drivers. Does anyone have
a schematic I could use? I'd like to be able to run down to Radio Shack
and get the parts if possible, so I guess simple is better.

Thanks,
Monte

Well, it all depends on how much current you need. This site has some
unique and simple bucking regulators that might be adaptable to your needs:

To drop 12V using a linear regulator would waste a lot of power as heat and
require bulky heatsinks. A switching-type regulator would be much more
efficient.

I forgot the current part. Might be up to 20A. I'll check out the web
site you gave.

For short tests use a couple of 12V car batteries in series.
Cheapest way.

There are dc-to-dc converters available. 48v dc convertes have an
input range of 36vDC to 60vDC. you will have to google for
them.
