* F3.1 Fuse KTK25 included in FEX-425-Int inside D5 converter module
Fuses and fuse holders for 2-phase field supply
Single-phase Transformer T3 for field supply to match voltage levels
The field supply units’ insulation voltage is higher than the rated operating voltage
(see Chapter Field supplies), thus providing an option in systems of more than 500 V
for supplying the power section of the converter directly from the mains for purposes
of armature supply, and using an autotransformer to match the field supply to its
rated voltage. Moreover, you can use the autotransformer to reduce the voltage
ripple. Different types (primary voltages of 400...500 V and of 525...690 V) with
different rated currents each are available.
