Using an auto-transformer is always an economical solution when you need to step down the voltage from 230V to 120V 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 stray fields. The auto-transformer can be mounted horizontally using a steel washer or an epoxy potted center with a mounting hole.
