Thank's Marris,
Not that I don't like the geckos, but I have to use the a3977 chip
from allegro to build a controller for our machine, spending almost
$1000 for a set of geckos (that's what is going to cost here in
Brasil) is out of the question.
So, I need to keep the PS at 30 to 34V. no more no less, that's why
I asked about the trans.
I'm trying to get it at that voltage range with a unregulated PS.

Thank's.
