Wall-Mount Active Harmonic Filter - Cost Effective Power Quality Modules with PFC

Press release date: January 6, 2014

Hopkinton, MA – Schaefer Inc. is proud to introduce our new PB-W (Wall-Mount) Series of three-wire and four-wire active (3x200VAC to 3x480VAC) harmonic filter modular systems that are designed to meet IEEE-519. The Power Balance (PB-W) family is scalable and offers a cost-effective solution for improving power quality for tower buildings as well as automation, wind turbine and a wide range of industrial applications. The Wall-Mount versions are ideal for mounting in small and confined areas, as well as the required “out of reach” locations.

These active harmonic filters have ultra-fast (21µs) 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 <300µs, load="" balancing="" between="" phases="" and="" unload="" neutral="" wire="" and="" grid="" resonance="" detection.="" communication="" connections="" via="" ethernet="" and="" ethercat="" system,="" ethernet="" tcp/ip="" interface="" permits="" control="" via="" browser.="" subsystems="" display="" control="" unit,="" active="" sensor="" unit,="" modbus,="" pq="">

Harmonic currents generate power that cannot be used and consumes electrical system capacity. Large quantities of harmonics can lead to malfunctioning of the system that results in downtime and increase in operating costs. The PB-W Series active harmonic filter monitors the current signal and compensates for the unwanted elements of the measured current, thus eliminating harmonic oscillations and consequently costs savings for reactive energy.
