Need help selecting a new transformer

[bgolash]

Hi
I need to change my z axis stepper to a larger motor. It seems
I`m loosing steps on the Z axis. I have a secondary power supply
in place that has a max amp rating of 4 amps. It seems now the
supply is too small for the homeshopcnc stepper I`d like to use.
So I need a new transformer for the z and a potential 4th axis.
I don`t have room in the enclosure for a toridal transformer so
I need a recommendation for a standard square transformer and
also a recommended voltage and amp rating. I`m hoping someone might
have a source for this transformer. I looked at Mouser and Digikey
but a 10 amp 48 volt transformer seems hard to find. I use Gechos
on all the axes.
Regards Barry

Hi Barry

Check Phil's page http://pminmo.com He has a 24V, 10A tranny specked out. It's not the 48V you were asking for.
