Notes
  • Transformers with the rated output voltages ≦ 50 V can be used as safety transformers to IEC/EN 61558.

When ordering, the part no. must include the following details:

STZ0.06(*/*)

1. Wildcard ≙ Nominal input voltage

2nd Wildcard ≙ Nominal output voltage

Ordering example

  • desired part no. STZ0.06
  • Desired rated input voltage 230 V
  • Desired rated output voltage 12 V

The correct part no. is

STZ0.06(230/12)
