Figure 174: DE4-LN... mains chokes
h
When the frequency inverter is working at its rated current
limit, the mains choke causes a reduction of the frequency
inverter’s maximum output voltage (U
2
) to about 96 % of
mains voltage (U
LN
).

For technical data for the DE4-LN series mains chokes, see
installation instructions AWA8240-1711, for those of the
DDK series, refer to the main Industrial Switchgear cata-
logue.

Mains chokes reduce the magnitude of the current harmo-
nics up to about 30 % and increase the lifespan of
frequency inverters and upstream-connected switching
devices.
