  • ±5 % tapping on the primary side

CAD data

  • 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

Sample order

  • requested type DTI0,1
  • requested rated input voltage 200 V
  • requested rated output voltage 18,5 V
  • requested vector group Dy(n)5

The correct type designation reads DTI0,1(200/18,5)Dy(n)5

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