Description
|
|
Autotransformers in solid construction, completely potted under vaccum with highly insulating polyurethane cst resin. The windings are connected to each other, no galvanic separation.
Isolation housing with 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
