Designed and tested according

  • IEC/EN 61558-2-2 / 2-4 / 2-6
  • UL 5085-2
  • CSA 22.2 No. 66

For use according to

  • IEC/EN 60204-1

Typical applications

  • Control voltage circuits
  • Functional low voltage
  • Safety low voltage
  • Protective separation

Basic equipment

  • Separate windings
  • Insulation class B / F from 8,0 kVA
  • Ambient temperature –25 to 40 °C
  • Connection terminal (<=115 A)
  • Frequency 50/60 Hz
  • ±5 % tapping on the primary side

CAD data

  • 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

Sample order

  • requested type DTZ0,1
  • requested rated input voltage 200 V
  • requested rated output voltage 36 V
  • requested vector group Dy(n)5

The correct type designation reads DTZ0,1(200/36)Dy(n)5

 

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