Other voltage combinations can be designed
on request.
In most applications the standard configuration
is needed which is described in the
table. If other voltage combinations are
needed, the input voltage and the output voltage
must be added to the order like follows:
DT3,15(*/*)-MED
1st place holder ^=
rated input voltage
2nd place holder ^=
rated output voltage
Sample order
• requested type DT4,0...-MED
• requested rated input voltage 400 V
• requested rated output voltage 230 V
The correct type designation reads
DT4,0(400/230)-MED
