Toroidal Auto-Transformer Models

Incorporate a Compact, Efficient Toroidal Auto Transformer

Our standard line of toroidal auto-transformers can be used to step up or step down a line voltage, depending on your equipment’s input voltage requirement. Auto-transformers are a single winding type of transformer, with various taps and with no isolation between the primary and secondary.

Auto-transformers are ideal when your application doesn’t have voltage isolation requirements (between the input and output) and when you have limited space. The primary and secondary windings of an auto-transformer share common turns, so you can expect a size and weight reduction of about 30-70%, which results in a significant cost reduction as well.
