SCHAEFER PB Series three-wire and four-wire active harmonic filter modular systems meet IEEE 519. The filters have ultra-fast (21?s) reactive power compensation, phase compensation current of 60A to 300A extendable and harmonic correction is provided for harmonics to the 50th order. Additional features include flicker compensation, ultra-fast response time of <300?s, load balancing between phases and unload neutral wire and grid resonance detection. Product family is scalable and provides a practical solution for improving power quality for many applications.
