Variable frequency drives

Demand more clean power.

The CPX series of variable frequency drives uses advanced 18-pulse clean power technology that significantly reduces line harmonics at the drive input terminals – resulting in one of the purest sinusoidal waveforms available. They prevent upstream transformers from overheating and overloading, enabling the application of generators and other high-impedance systems.
