The new KDR Optimized Drive Reactors have been designed to provide the same rugged reliability customers have come to expect from TransfabTMS / TCI products. These reactors are now available for both the input and the output of PWM drives. The KDR reactors for the input are available in two ratings versions, Low "Z" (low impedance) and High "Z" (high impedance). The Low "Z" units can be used in any application where traditionally either a 1.5% or 3% impedance reactor would be applied. The High "Z" units can be used in any application where traditionally a 5% impedance reactor would be applied. The output reactors have been selected based on the unit's ability to withstand the rigors of variable system characteristics.

KDR at the Input of the Drive

KDR Optimized Drive Reactors applied to the line side of a PWM drive will greatly improve the overall performance of the drive. The additional circuit inductance will reduce AC voltage waveform line notching, DC bus overvoltage trips, inverter overvoltage, poor total power factor, and cross-talk.

Reduce Nuisance Tripping
Reduce Voltage Notching
Reduce Harmonic Distortion
Reduce Cross Talk
Improve True Power Factor
Protect Components from Damage

KDR at the Output of the Drive

The addition of a KDR Optimized Drive Reactor to the output side of a drive will dampen overshoot peak voltage, reduce motor heating and audible noise which ultimately helps to extend the life of the motor. The KDR reactors will also help prevent inverter instantaneous overcurrent trips because they provide needed inductance when the load on an inverter has as abnormally high capacitance.

Dampen Overshoot Peak Voltages
Reduce Motor Heating
Reduce Audible Noise
Extend Motor Life
