Schaefer Inc. is proud to introduce a new series of Active Harmonic Filters and Advanced Display & Measurements Functionally. Three-wire and four-wire Active Harmonic Filter modules/systems that are designed to meet IEEE-519 (5% TDD) and Mil-Std-1399 (<3% THDi). The Power Balance & Kxxx Series family are scalable and offer a cost-effective solution for improving power quality for wide range of Heavy Industrial and Military applications.

 

Communication connections via Ethernet TCP/IP, Ethercat system and ModBus. New advanced functions include resonance frequency detection and automatic protection, trace waveform display/capture (filter current, load current, grid current & voltage), new series of high IP/NEMA rated air and liquid cooled active harmonic filters (modules & systems).

Reducing harmonics (TDD reduction to 5% / <3% THDi Mil-Std-1399)

Individual harmonic compensation adjustment

Rebuilding distorted three phase currents/voltages

Four wire zero sequence current compensation.

Power Factor (phase displacement) correction/adjustment

Balancing 3 phase currents

60A to 1000s Amps of compensation current
