Autotransformer Verified listing

An autotransformer is defined as one that has an electrical contact connection between the primary and secondary windings so that they have part of a winding in common.

Autotransformers are ideal for voltage adjustment for commercial and industrial machines. They provide an efficient, low-cost way of serving the proper voltage to motors and compressors, lathes, CNC machines, and other industrial equipment requiring a step up or down from a building's service voltage.
