Hi I have a little problem.
Specs for transformers are messing with my head.
Look at the pictures

On first it says on secondary 207VAC and after a Gretz it says 265V.
How is that posible?
On other pic there is Hammond transformer. His specs are 190-0-190 on secondary. And again it is 265V after two solid-state diodes 🙂
Could someone tell me how it is possible?

I think what happens sometimes is, engineers and designers, casually draw up these up - not paying attention to the finer details.
here's a good rules of thumb:
HALF WAVE (one diode) = acV x 1.1 = dcV
FULL WAVE (two diodes w/ grounded CT) = acV x 1.4 x .5 = dcV
FULL WAVE BRIDGE (four diodes, + or - node grounded) = acV x 1.4 = dcV

HALF WAVE (one diode) = acV x 1.1 = dcV
FULL WAVE (two diodes w/ grounded CT) = acV x 1.4 x .5 = dcV
