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

Technical notes

Important notes:

According to IEC/EN 61 558 transformers with rated output voltages ranging from 18.5 V to 42 V can be used as safety transformers.

  • UL/CSA only up to 600 V (incl. tapping)
  • CUR according to UL-File XPTQ2. or XPTQ8.E168819 (Transformers, General Purpose – Component bzw. Transformers, General Purpose Certified for Canada – Component)

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

  • DTI0,1(*/*)
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
  • 3rd place holder ≙ vector group
