Re: [CAD_CAM_EDM_DRO] 28v power transformer

Bob,

Many transformers have four wires on the input. They are designed for either
110 or 220 volts. You will wire the windings in series for 220 and in
parallel for 110.

If you go to the Plitron web page (www.plitron.com) you can display a
drawing that shows you haw to make the connections.
