Fields of application
|
|
|
Autotransformers enable the operation of 230 V (110 V) devices with 110 V (230 V) mains voltage.

Description
|
|
|
Autotransformers in solid construction, completely potted under vacuum with highly insulating polyurethane cast resin. The windings are connected to each other, there is no galvanic separation. The isolating housing has handles.
These transformers have twice the power of an isolation transformer with the same size. For critical circuits, the phase of the net connection against earth has to be tested, when using an autotransformer 230 V -> 110 V.
Special types
- other primary or secondary voltages
- three-phase type
