VLT Advanced Active Filters

Danfoss Industries offers VLT Advanced Active Filters, AAF 005. These eliminate harmonic distortion from non-linear loads and improve system power factor. Proven VLT power electronics re-establish optimal sinusoidal power and unity power factor by generating and injecting counter phased harmonic and reactive currents. The modular construction offers the same characteristics as the Danfoss high power VLT family, including high energy efficiency, user-friendly operation, back channel cooling and high enclosure grades. Danfoss Advanced Active Filters can compensate for individual VLT drives as a compact integrated solution or can be installed as a compact stand-alone solution at a common point of coupling, compensating for several loads simultaneously. Danfoss Active Filters can operate at medium voltage level by means of step-down transformer. The perfect solution for restoring weak networks, increasing network capacity, increasing generator power, meeting compact retrofit demands, securing sensitive environments, utilising energy savings. Voltage range: 380-480 V AC, 50-60 Hz. Power range: 190 A, 250 A, 310 A, 400 A, 500 A, up to 4 units can be paralleled for higher power. Enclosure degree: IP 21, IP 54 hybrid.
