Sample order

· requested type DT0,1
· requested rated input voltage 1000 V
· requested rated output voltage 12 V
· requested vector group Dy(n)5

The correct type designation reads DT0,1(1000/12)Dy(n)5

Higher outputs on request.

The unambiguous article number of your configuration will be defined by trafomodern during the offer- and order process

Technical notes

Important notes:

Static shield windings is additional shielding between primary and secondary sides.

For versions with increased climate resistance, the transformers is supplied with a specially insulated finish.The finish enables the transformer to be used in areas of high humidity.

Transformer version with reinforced insulation upon request.
