TCI Line Reactors, KDR Series Product Feature Spotlight

TCI’s KDR series is a high performance line reactor in a compact package. TCI’s KDR series is available for the line or the load side of a PWM drive helping to improve the overall performance.  The additional circuit inductance helps reduce AC voltage waveform line notching, DC bus overvoltage trips, inverter overvoltage, poor total power factor, and cross-talk.

TCI’s KDR is a 3 phase unit in a patented high quality bobbin construction, and is input and output specified.  Available in 240, 480, and 575 volts AC, with 10 horsepower at 64 watts and a frequency of 50/60 hertz.  This series has an ambient temperature of 40 degrees Celsius

The KDR line reactor comes equipped with two input impedance protection levels, Low Z for Low Impedance and High Z for High Impedance.  Units with a Low Z are used in applications where traditionally either a 1.5 or 3 percent reactor would be applied, and units offering a high Z can be used in any rugged application where traditionally a 5 percent reactor would be applied.

This series has a short term overload rating of 2 hundred percent, rated I for a minimum of 3 minutes.
