...it's the same rating, with the center tap as the zero reference.
The DC voltage is based on a full wave rectifier using the center tap.
Be careful when using such a transformer in a full wave bridge ciccuit.
Sometimes transformers designed for full wave CT operation do not have HV
insulation at the CT, since it is assumed by the manufacturer to be at
ground potential. Running it in a FWB could result in a zorch to ground at
the CT of the winding.
The same precaution is recommended when placing the filter choke between CT
and ground instead of the more traditional positive side of the filter. The
high ripple voltage that appears across the choke will also appear at the
transformer CT and could cause failure of the transformer.
I'll look up those ratings in my UTC catalogue this evening and verify.
