VLT® Advanced Active Filter AAF 006 A flexible and adaptable solution for central or de-central harmonic mitigation. Danfoss Advanced Active Filters can compensate for individual VLT® drives or can be installed as a compact stand-alone solution at a common point of coupling, compensating for several loads simultaneously. Consequently the filter ensures optimal harmonic suppression independent of the number of loads and their individual load profile. In addition the active filter corrects the power factor and balances the phase load providing an optimal energy utilization. This improves the system efficiency and increases the grid robustness to avoid downtime. E-frame The VLT® Advanced Active Filter is easily controlled via the user-friendly LCP, sharing design and programming structure with the VLT® drives series. Without dismounting existing installation, the VLT® Advanced Active Filters are easily retrofitted to the existing installation, where harmonics are increased because of enlarged employment of non-linear loads such as variable speed drives. Voltage range 380 – 480 V AC 50 – 60 Hz Current range 190 A, 250 A, 310 A, 400 A. Up to 4 units can be paralleled for higher power. Enclosure degree IP 21/NEMA Type 1 IP 54/NEMA Type 12 The extensive re-use of proven VLT® components and the modular construction ensures a high reliability and at the same time offers high energy efficiency, back-channel cooling and high enclosure grades without size encrease.
