Technical notes

Important notes:

According to IEC/EN 61 558 transformers with rated outout voltages ≤ 50 V can be used as safety transformers
For versions with increased climate resistance, the transformers is supplied with a specially insulated finish.

  • UL/CSA only up to 600 V (incl. tapping)
  • CUR for EIS130 or EIS155 according to OBJY2/8.E160829

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

  • STZ5,3(*/*)
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
