Technical notes

Important Note:

  • The Transformers STN are designed for use in control circuits according to VDE 0113 bzw. IEC/EN 60 204.
  • UL/CSA only up to 600 V (incl. tapping)
  • CUR according to UL-File XPTQ2. or XPTQ8.E168819 (General Prpose-Component)

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

  • STN0,1(*/*)
  • 1st place holder ≙ rated input voltage
  • 2nd place holder ≙ rated output voltage
