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
