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:D4TF(*/*)*1st place holder  ≙ rated input voltage
2nd place holder ≙ rated output voltage
3rd place holder ≙ vector group
