Active Harmonic Filter

Active Harmonic Filter

Modular System 60 A to 300 A extendable
Short Description: 

General Information

The PB-SERIES is an active harmonic filter system for tower buildings as well as automation, windturbine and various other industrial applications eliminating harmonic oscillations and consequently costs for reactive energy. The filter monitors the current signal and compensates for the unwanted elements of the measured current. Thus, the filter ensures a harmonic suppression independently of the number of loads. Furthermore the filter corrects the power factor, improving the systems’ efficiency while reducing harmonic pollution.
