Technical notes
Important Note:
- According to IEC/EN 61 558 transformers with rated output voltages ranging from 12 V to 42 V can be used as safety transformers.
- UL/CSA only up to 600 V (incl. tapping)
- CUR according to UL-File XPTQ2. or XPTQ8.E168819 (General Purpose-Component)
- From STI0,315 (*/12) —> STZ
When ordering, the following information must be added to the type designation:
- STI0,06(*/*)
- 1st place holder≙ rated input voltage
- 2nd place holder≙ rated output voltage
