6.6 Line inductance
Line inductance means including chokes on each of the three power lines.
Its function is to reduce the harmonics generated in mains. The
recommended value is given by the formula:
To simplify the choice, we could consider optimum the values given in the
following table:
T. H6/6 Line inductance selection according to the power supply or
compact drive installed.
PS-25B4
L (mH) 1
Irms (A) 40
When not installing the mains filter, we recommend to use the line
inductance in order to minimize disturbances, although is warned that this
inductance does not guarantee the compliance with the CE seal.
MANDATORY. Do not install line chokes in line with RPS or XPS
regenerative power supplies. They generate interference in the
regenerating mechanism.
