9.9 DX-LN… mains chokes
The DE1 variable speed starter's rated input currents serve as the basis used
to determine which mains chokes should be used.

If the DE1 variable speed starter is being run at its rated
operational current limit, the variable speed starter's maximum
possible output voltage (U
2
) will be reduced to about 96% of the
mains voltage (U
LN
) due to the mains choke at a u
k
value of
approximately 4%.
→
If using DE1-34… variable speed starters, the mains choke's u
k
value must not exceed 4%, as these devices feature a "lean DC
link."
→
Mains chokes reduce the magnitude of the current harmonics
up to about 30 % and increase the lifespan of variable speed
starters and upstream-connected switchgear.
Further information and technical data on the mains
chokes of the DX-LN… series is provided in Instruction
leaflet IL00906003Z.
