Re: [CAD_CAM_EDM_DRO] Question on Power Supply

Luke,

I agree with Ron. For a small power supply it would be best to buy one.

If you want to experiment and build your own, look for a transformer that
has an output of about 18 volts AC at about 4 amps. This will give you a DC
voltage of about 26 volts once you run it through a bridge rectifier and
charge it up in a capacitor.

The next step is to find a bridge rectifier and a filter capacitor.

If you decide to build one, please contact me off line and I will help you.
