Product Overview
- An auto-transformer is an electrical transformer with only one winding. The “auto” (Greek for “self”) prefix refers to the single coil acting alone, not to any kind of automatic mechanism. In an auto-transformer, portions of the same winding act as both the primary winding and secondary winding sides of the transformer. In contrast, an ordinary transformer has separate primary and secondary winding’s which are not connected to each other.
- The auto-transformer winding has at least three taps where electrical connections are made. Since part of the winding does “double duty”, auto-transformers have the advantages of often being smaller, lighter, and cheaper than typical dual-winding transformers, but the disadvantage of not providing electrical isolation between primary and secondary circuits
