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.

  • CUR according to EIS 130 or EIS 155 to OBJY2. or OBJY8.E160829 (Systems, Electrical Insulation – Component bzw. Systems, Electrical Insulation Certified for Canada – Component)

When ordering, the following information must be added to the type designation:

  • DTF100(*/*)*
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
  • 3rd place holder ≙ vector group
