Ouput filters are intended for suppression of high-frequency harmonics of carrier frequency of three-phase output voltage of switchboards with frequency control.
Output filter is connected up between switchboard's output and step-up transformer. Filter's rated curent circuit should be corresponding with rated output curent of the switchboard.
Output filters for frequency converters for rated current 160...1200À. Coefficient of current and voltage harmonicity curve distortion:
KUoutp, ÊIoutp= not more than 5%
There are coefficients of current and voltage harmonicity curve distortion (KUoutp, ÊIoutp) of metering data for frequency converter ELEKTON-05-400 presented
