Designed and tested according

  • IEC/EN 61558-2-1 / EN 60076-11

Typical applications

  • Inverter applications

Basic equipment

  • Separate windings
  • Insulation class B / F 25 kVA
  • Ambient temperature –25 to 40 °C
  • Connection terminal (<=115 A)
  • Frequency 50/60 Hz
 
  • 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

Sample order

  • requested type D4TB20
  • requested rated input voltage 400 V
  • requested rated output voltage 320 V
  • requested vector group Yd5

The correct type designation reads D4TB20 (400/320) Yd5

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