VFD Input KDR, 690V (High Z - 5% Reactor)


Transient voltages, commonly caused by capacitor switching or the switching of large load blocks, can result in an overvoltage condition of the DC bus. This overvoltage condition will cause the drive to shut down in order to protect its components. These transients can sometimes be very severe and too quick for the drive to shut down. The addition of a Trans-Coil KDR series reactor can prevent drive shutdown and even protect components from possible damage.

KDR reactors will reduce input line distortion which is caused by the non-linear characteristics of drives. The KDR will limit the inrush current to the rectifier, rounding the waveform, reducing the peak currents and lowering the harmonic current distortion. High peak currents may cause distortion of the voltage waveform. The reduction of those peak currents also reduces total harmonic voltage distortion at the point of common coupling.

Drive input currents rich in harmonics result in a decrease in total input power factor to the drive. The addition of a KDR will reduce the RMS current through the reduction in harmonic content, thereby improving the total power factor.

• Reduce Nuisance Tripping
