Re: [CAD_CAM_EDM_DRO] Re: Power supply

Peter,

It's true that the buck transformer is rated at 4 amps, but if applied
to the primary side of the power circuit as is usually practiced, then
that means you would be drawing 4 amps through the 120 volt primary, or
delivering about 480 watts to the secondary of the original
transformer. The original enquirer didn't spec the size of the original
transformer, but 480 watts sounds like a reasonable initial guess.
