Active Harmonic Filters

The PB-SERIES are an active harmonic filter system for large buildings as well as automation, wind-turbine 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 system efficiency while reducing harmonic pollution.

Mechanical and electrical modifications to standard modules are available. In addition, Schaefer can design and manufacture fully custom solutions. Let Schaefer be your Custom Power Supply Design Solution Partner.
