Re: [CAD_CAM_EDM_DRO] Question on Power Supply

Luke,

It looks like a power supply in the range of 28 to 30 volts. Just check for
the maximum that you can use.

You can build your own power supply. All it takes is a transformer, bridge
rectifier and a capacitor.

Most power supplies are unregulated.

If you decide to build your own, I can help you.

I also have an interface breakout board that will help.
