Voltage ratings
The maximum available armature voltages have been calculated using the following assumptions:
− U
VN
= rated mains voltage, 3-phase.
− Voltage tolerance ±10 %.
− Internal voltage drop approximately 1 %.
If a deviation or a voltage drop has to be taken into account in compliance with IEC and VDE standards, the
output voltage and/or the output current must be reduced.
