Toroidal auto-transformers are always an economical solution when you need to step down the voltage from 230V to 120 V or vice versa, and the equipment already has a fully isolated transformer or when the components do not require an isolated transformer.
The toroidal construction of an auto-transformer offers important advantages in comparison with an E/I lamination core transformer, like smaller physical size and weight, 30-70% reduction (depending on secondary voltage) and very low magnetic strayfields. The auto-transformer can be mounted horizontally using a steel washer or our Poly-Mount, a plastic insert, or an epoxy potted center with a 1/4" mounting hole. See our Mounting and Hardware page for more information.
With its small size and weight, the toroidal auto-transformer can be installed easily in existing equipment or supplied in an optional enclosure with or without cord, plug and receptacle.
