Re: Help putting together Power Supply

A day late, but...

this looks like the MPJA 10 amp unit

If you use the Xylotex driver, it maxes at 35 Volts so you can only
use one x-frmr at 24.

if you use Gecko, you can tie the units together and get twice the
voltage ( same amps as one unit)

I am not sure, and hopefully, someone will chime in here, but if you
connnect one transformer as 24 and the other as 12 v, you could get
36 volt. don't know if there are any problems with doing that ???

regardless, the 1.414 rule stands and you will then drop about a volt
from the rectifier. ops', 24 vac out, less a volt for the rectifier,
then 1.414 to get your final DC Buss voltage.

I did a mix on a system. some 5.4 volt steppers and some 1.7 volt
ones. I used seperate power supplies to get the best performance.
