Designed and tested according

  • IEC/EN 61558-2-1 / EN 60076-1
  • UL 5085-2
  • CSA 22.2 No. 66

For use according to

  • IEC/EN 60204-1

Typical applications

  • Voltage adjustment
  • Generation of four-wire networks based on three-wire network
  • Power transfer

Basic equipment

  • Separate windings
  • Insulation class B / F from 6.3 kVA
  • Ambient temperature –25 to 40 °C
  • Connection terminal (<=115 A)
  • Frequency 50/60 Hz
  • ±5 % tapping on the primary side

CAD data

  • 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 UL-File XPTQ2.E168819 to 6,3 kVA (Transformers, General Purpose - Component bzw. Transformers, General Purpose Certified for Canada - Component)
  • 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:

DT0,1(*/*)*
1st place holder ≙ rated input voltage
2nd place holder ≙ rated output voltage
3rd place holder ≙ vector group

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
