Line reactors for single- and 3-phase connection of field converters
Field converters DCF803-0016, FEX-425-Int and DCF803-0035 need additional external line
reactors. Field converters DCF803-0050, DCF804-0050, DCF803-0060 and DCF804-0060 do not
need additional line reactors since they already have internal line reactors.
* 3-phase operation or single-phase operation
Line reactors (details see chapter Line reactors IEC)
Auxiliary transformer (T2) for electronic system / fan supply
The converter requires various auxiliary voltages, e.g. the unit’s electronics require 115 V or 230 V
single-phase. The fans require 230 V single-phase or 400 V / 460 V /500 V 3-phases, according to
their size. The auxiliary transformer (T2) is designed to supply the unit’s electronic system and all the
single-phase fans for converter sizes H4 ... H6.
Input voltage: 380 ... 690 V single-phase; 50 / 60 Hz
Output voltage: 115 / 230 V single-phase
Power:1400 VA
