• The transformers STN are designed for
use in control circuits according to VDE
0113 and IEC/EN 60 204
• UL/CSA only up to 600 V (incl. tapping)
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
Sample order
• requested type STN0,1
• requested rated input voltage 200 V
• requested rated output voltage 18.5 V
The correct type designation reads
STN0,1(200/18.5)
The unambiguous article number of your
configuration will be defined by trafomodern
during the offer- and order process.
