I have one that does both, for a larger stepper motor.
It can take a bit of effort to find a DC PSU that can actually provide
5.5A the motor can 'pull', it's a lot easier
to get a transformer for one (my driver is 48VAC-80VAC OR 24VDC-110VDC)
Jus a transformer will provide the amps your 'pulling' and of course
without any measures, spikes etc can happen. A switching
power supply has bit of protection there. I think the driver probably
has some simple rectifier in it, I would expect much there.

Some of the larger size Stepper motor drivers will use AC input power. I
assume all that is needed is a transformer that is rated for the required
current (and a fuse.)
Most people are using these Meanwell-style switching power supplies but it
seems AC power might be better
Questions
Is there is the best type of transformer? Is there a good supplier?
What about back EMF? Not knowing how the driver works I wonder what
happens when the motor is breaking. Can there be an overvoltage problem?
