Step-Up/Step-Down Autotransformer -- F-302U
from Triad Magnetics

Description. Triad autotransformers are single winding transformers in which the primary coil is a fraction of the entire winding for voltage step-up or the secondary coil is a fraction of the entire winding for voltage step-down (see Technical Notes for an equivalent circuit diagram). In ordinary... [See More]

Custom Toroidal Auto Transformers
from Amgis Toroidal Power Products, LLC

Using a toroidal auto transformer is 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. Advantages of Toroidal Auto... [See More]
