• According to IEC/EN 61 558 transformers
with rated output voltages ranging from
18.5 V to 42 V can be used as safety transformers.
• UL/CSA only to 600 V (including tapping)
When ordering, the following information
must be added to the type designation:
DTI0,1(*/*)*
1st place holder ^=
rated input voltage
2nd place holder ^=
rated output voltage
3rd place holder ^=
vector group
Sample order
• requested type DTI0,1
• requested rated input voltage 200 V
• requested rated output voltage 18.5 V
• requested vector group Dy(n)5
The correct type designation reads
DTI0,1(200/18,5)Dy(n)5
The unambiguous article number of your
configuration will be defined by trafomodern
during the offer- and order process.
