Triad Step Up/Step Down Leaded Autotransformer 50-2000VA Single Primary and Secondary

The Triad Autotransformers Series is designed as a single-winding transformer 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. In ordinary double-wound power transformers, the primary and secondary are isolated and all the power is transferred by induction. In Autotransformers, part of the power is transferred conductively through the windings. Triad autotransformers come in a variety of configurations, case types and output Wattage (VA) ratings in excess of 2000W. A universal isolation/autotransformer/voltage control model is available with up to a 4,000 W output rating when operated as an autotransformer.
