Triad Magnetics’ autotransformer power transformers are available in single winding step-up transformer models, in which the primary coil is a fraction of the entire winding, and step-down transformer models, in which the secondary coil is a fraction of the entire winding.

Standard double wound power transformers feature isolated primary and secondary coils, so all power transfer is conducted by induction. Autotransformers transfer power in between coils in part conductively through the windings. This leads to increased efficiency, smaller size, a higher degree of voltage regulation, and other important benefits.

Triad offers 14 different autotransformer power transformers, including a universal isolation/autotransformer/voltage control model capable of operating at an output wattage rating of 4,000 output watts.

The specification table below details the capabilities of each of these models. To learn more, contact Triad Magnetics today.

Autotransformer Power Transformers
Description N/A 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. 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 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.
