A line choke is used to provide better protection against over voltages on the line supply and to reduce the harmonic distortion of the current produced by the inverter based drive. It is a cost-effective solution to reduce harmonic distortion. It has no visible benefits but is makes effect on reliability and life span of vfd and pfc capacitor. Features - easy to add to an existing vfd based system. - reduce power supply harmonic currents. - reduce the overall input current to the drive. - provide additional protection against mains voltage spikes. - improve the true input power factor. - reduce cross-talk between drives. - protects capacitors from harmonic resonance. - prevent circuit breakers from tripping due to high current spikes. - minimizing nuisance over-voltage trips due to line transients.
