OPTIMIZED LINE REACTORS
KDR line reactors are electrical components that help to
protect 6-pulse rectiers and power conversion devices
such as variable frequency drives (VFDs). When used
in conjunction with a VFD, a KDR line reactor can help
reduce harmonics and protect the drive from harmful
voltage spikes. 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.
Typical Applications with VFDs
• HVAC Chillers
• Pumps
• Oil rigs
• Conveyors
• Sprinkler irrigation systems
