Auto Transformer

Auto Transformer

Toroidal auto transformer is always an economical solution when you need to step down the voltage 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. Decknetics’ 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. With its small size and weight, the auto-transformer can be installed easily in existing equipment or supplied in an optional enclosure with or without cord, plug and receptacle.


Significant Size and Weight reduction, low cost.
