Variable frequency drives

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.
