| Using
an 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.
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 auto-transformer
can be installed easily in existing equipment or supplied
in an optional enclosure with or without cord, plug
and receptacle. |
