Technical notes

Important notes:

According to IEC/EN 61 558 transformers with rated output voltages < 50 V can be used as safety transformers.

Specially insulated finish for transformers with increased climate resistance.

  • UL/CSA only up to 600 V (incl. tapping).
  • CUR accroding 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:

  • DTZ0,1(*/*)*
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
  • 3rd place holder ≙ vector group
