RE: [CAD_CAM_EDM_DRO] Re: power supplies form those 24v transformers

With these transformers you basicly get 12 volts ac per winding.
2 windings per transformer. So here is what you should get at 110 ac

12 > 16.9 dc
24 > 33.9 dc
36 > 50.9 dc
48 > 67.8 dc

But here is what I get straight off the cap at 122.

12 > 20.0 dc
24 > 40.0 dc
36 > 60.0 dc
48 > 81.1 dc

After I started think about this, If you set up the right wiring, with a
selector switch it would be posible
to have a power supply that would supply you with 4 voltages. 4 for the
price of 1.

Thanks, Jerry for the measurements.

The voltage sounds awfully high....I calculate over 80 v
open circuit after rectification/ filtering.

Sounds like a potential amp popper.
