2.5 Line choke (accessories)
To reduce input side current harmonics, additional inductivity
can be installed into the line supply to the inverter.
These chokes are specified for a maximum supply voltage of
480V at 50/60 Hz.
The protection class of the chokes is IP00 and they must
therefore be installed in a control cabinet.
For frequency inverters with an output of 45 kW or more, a
line choke is recommended where several devices are being
used, in order to avoid possible adverse effects of one device
on another. In addition, the charging currents (mains voltage
fluctuations) are significantly reduced.
