RE: [CAD_CAM_EDM_DRO] Choosing a Power Supply?

Download the G201 manual, and also the "Stepper Motor White paper(full
version)" from the Geckodrive web site, and give them a quick read. This
should answer most of your questions.

Subject: [CAD_CAM_EDM_DRO] Choosing a Power Supply?

Having more or less settled on using a Gecko drive (probably the 201) for my
stepper
retrofit....

I'm now thinking that at some point I'll need a power supply!

I'm a bit "slow" when it comes to electricity.... that is, I'm ignorant...

What I THINK I need;
A power supply that will supply up to 70 VDC (the maximum that the Gecko 201
will
handle, as I read the specs), at 6Amps (I have 3 steppers rated for 2Amp per
phase...
2amps times thee motors; 6 Amps?).

Given this, should I be looking for a 60-70VDC supply at 7Amps (a bit of
headroom for
the motors)???

There are currently 1250 "Power Supplies" in the Business and Industrial
section of eBay...
you'd think at least ONE of them would be more or less what I'm looking for,
wouldn't you?

Are there any other considerations when looking for a Power Supply that I"m
not aware of?

I don't have the money to buy one immediately... I want to buy the Gecko's
first, then in
another month or two, I'll get the power supply about the time I have a good
start on the
mechanicals of the retrofit...
I have a long way yet to go!

Any advice is appreciated!
