Engine choke - 50 - 200 Hz | COMBILINE
KEB COMBILINE Mains Input and Motor ChokesThe B6 rectifier input circuit in the input of variable speed drives causes current ripples that strain the DC-bus capacitors in the inverter and generate harmonic distortions in the utility grid. The mains choke (50/60 Hz) flatten the charging current and reduce harmonics. Both are important factors for the reliability and lifetime of the machine.
The modulated output voltage of the inverter stresses the isolation. This can result in problems in applications with long motor leads.
KEB COMBILINE motor chokes flatten the output currents, reduce the strain on the isolation and are available for the output frequencies...50 Hz, ...100 Hz and ...200 Hz.
