Proven VLT® power electronics re-establishes optimal sinusoidal power and power factor of 1 by generating and injecting counter phased harmonic and reactive currents. The modular build-up offers the same characteristics as our High Power VLT® family, including high energy efficiency, user-friendly operation, back channel cooling and high enclosure grades. Danfoss Active Filters can compensate individual VLT® drives as a compact integrated solution or be installed as a compact stand-alone solution at a common point of coupling compensating several loads simultaneously. Danfoss Active Filter can operate at medium voltage level by means of a step-down transformer.
