February 5, 2024 – Hammond Power Solutions launched the HPS Centurion S sine wave filter to condition the pulse-width modulated (PWM) output of variable frequency drives (VFDs) “into a nearly perfect sinusoidal waveform” to protect motors and cables in industrial applications.

The Centurion S serves as a low-pass filter, eliminating high-frequency components in the VFD output. This approach safeguards motors and feeder cables by reducing voltage reflection, harmonic distortion, bearing current, insulation stress, and motor noise.

By mitigating high-frequency currents and voltage spikes, the HPS Centurion S ensures lower temperature operation and improved overall performance. The filter optimizes the power delivered to the motor, adds HPS, contributing to increased operational efficiency and reduced energy consumption.
