CFX passive filter variable frequency drives

Demand more clean power.

Designed to meet the IEEE 519-1992 requirements for harmonic distortion, Eaton's CFX series of variable frequency drives uses tuned passive filters to significantly reduce line harmonics at the drive input terminals. It also prevents transformer overheating and overloading of breakers and feeders, enabling the application of generators and other high-impedance systems.

Harmonic mitigation techniques can help protect equipment from potential damage, reduce power generation to overcome losses, and eliminate utility fines. Learn more about harmonics. Watch the video below.

Core features of the CFX passive filter VFD

  • This cost-effective solution provides moderate reduction in voltage and current harmonics.
  • The drive provides increased input protection for the adjustable frequency drive and its semiconductors from line transients.
  • A wide range of communication protocols includes DeviceNet, PROFIBUS, Modbus RTU and Modbus TCP.
