KDR line reactors are electrical components that help to protect 6-pulse rectifiers and power conversion devices such as variable frequency drives (VFDs). A KDR line reactor can help reduce harmonics and protect the drive from harmful voltage spikes when used with a VFD. KDR line reactors are recommended on the input of each VFD in multiple drive applications.

Output of a VFD

KDR reactors are constructed with durability in mind and can be used on both the input and output of a VFD. When used on the output of a drive, KDR reactors reduce voltage distortion at the motor terminals extending the service life and minimizing insulation stress of any motor.

Use KDR Low “Z” Units For:

Any application where a 3% reactor would be applied. Reduction of nuisance tripping caused by:

• Transient voltages caused by capacitor switching
• Line notching
• DC bus overvoltage tripping
• Inverter overcurrent and overvoltage

Additional benefits include:

• Lowering the injected percentage of harmonic current
• Improving true power factor
• Reducing cross-talk between drives
• Adding impedance to drives with DC link chokes/reactors when more impedance is desired due to a relatively stiff source
