Mains chokes
A mains choke is an inductance which is switched in the in-
verter's mains cable. Using a mains choke delivers the follow-
ing benefits:
ƒ
less system perturbation:
the curved shape of the mains current approaches a sine
shape.
ƒ
reduction in effective mains current:
reduction in mains, cable and fuse load.
There are no limitations on using a mains choke together with
a motor filter.
Mains choke
Please note:
ƒ
when using a mains choke, the mains voltage on the in-
verter input is reduced slightly – typical voltage drop on
the mains choke at the rated point approx. 5%.
ƒ
A mains choke or mains filter always has to be used for
some inverters because otherwise the permissible rated
data for the components used may be exceeded as a result
of excess mains currents.

The following assignment applies to operation with rated
power.
