Single-Phase Autotransformer (T3) For Field Circuit (Adapt Voltage) - ABB DCS880 Series Hardware Manual

Single-phase autotransformer (T3) for field circuit (adapt voltage)

The field converters insulation voltage is higher than its rated voltage (see chapter Accessories). This
provides the possibility in systems with more than 500 V mains voltage to supply the field converter
directly. An autotransformer is used to match the mains voltage to the field voltage. Moreover, the
autotransformer reduces the voltage ripple. Different autotransformer types (primary voltages from
400 ... 500 V and from 525 ... 690 V) with several rated currents are available.
