2.7 Mains choke SK CI1
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 230 V or 480 V at
50/60 Hz.
All chokes have a protection class
corresponding to IP00. The choke used
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.
