RE: [CAD_CAM_EDM_DRO] Transformer question - ground ?

Is it a transformer supply, or a switch mode.

If it's a switch mode it will be 28V on and off load (assuming good load
reg)

Just be sure before you fry something.

Hi all,

I have two transformers from old Epsom printers.

each has a 28 volt and 8 volt output, plus one ground that was tied to
the frame.

I really only need the 28 volts, (I'm assuming 24 under load) and not
the other voltages.

I think I would be fine tying off the 8 volts (5 under load??) but my
question is about the ground.

Should I bring that to panel ground/ earth ground ?

should I tie it off and not connect it ?

Any suggestions ?

Dave:

In most cases if the ground wire is attached to the frame of the
transformer, then you would attach that ground lead to the machine's frame
or chassis.
