TCI has expanded the range of KDR Optimized Drive Reactors in order to protect and enhance the performance of 690 volt variable frequency drives. The KDR 690 volt reactors are designed to work with 690 volt drives and provide a safety buffer for drives with lower voltages.

Traditionally most variable frequency drive applications ranged from 208 to 600 volts. Higher voltage applications are being utilized more often in new developments. The 690 volt reactors provide an added buffer for these applications.

KDR Optimized Drive Reactors are designed to protect PWM drives and improve overall system performance. These high quality products can reduce or eliminate nuisance tripping, reduce harmonic distortion, and improve true power factor.

TCI Reactors applied to the line side of a VFD 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. The addition of a reactor to the output of a drive will dampen overshoot peak voltage, reduce motor heating and audible noise, helping to extend the life of the motor.

TCI is committed to developing and utilizing operating systems and technologies that ensure TCI consistently satisfies each customer’s quality and service needs while meeting all industry, statutory, and regulatory standards.
