RE: [CAD_CAM_EDM_DRO] Re: Transformer wiring hookup 110/220

Bernard,

Only thing is this specific transformer is not 2 windings, but two taps
on the same winding. I have used them for a number of projects and if
you connect them as black and red to 110 vac they are good for 10 amps.
I have not tried them on 220 vac. It is a good unit at a very good
price. MPJA carries them as a norma stock and not a close-out so they
are always available.
