Important notes:
According to IEC/EN 61 558 transformers with rated outout voltages ≤ 50 V can be used as safety transformers.When ordering, the following information must be added to the type designation:
- STA0,1(*/*)
- 1st place holder ≙ rated input voltage
- 2nd place holder ≙ rated output voltage
