Triad autotransformers are single winding transformers in which the
primary coil is a fraction of the entire winding for voltage step-up or
the secondary coil is a fraction of the entire winding for voltage
step-down (see Technical Notes for an equivalent circuit diagram). In
ordinary double wound power transformers, the primary and secondary
are isolated and all the power is transferred by induction. In auto-
transformers, part of the power is transferred conductively through
the windings. Triad autotransformers come in a variety of configurations,
case types and output watts (VA) ratings in excess of 2,000 watts. A
universal isolation/autotransformer/voltage control model is available with
up to a 4,000 output watts rating when operated as an autotransformer.
