Harmonic electronic filter VLT® AHF series

low-passpassivepower

VLT® Advanced Harmonic Filter AHF 005 and AHF 010 • Optimized harmonic performance for VLT® drives rated up to 250 kW • A patented technique reduces THD levels in the mains network to less than 5–10% • Perfect match for industrial automation, highly dynamic applications and safety installations • Line voltage and filter current: • 3 x 380/400/500/600/690 V...10-480 A* • * Achieve higher ratings by connecting in parallel. See AHF 005 or AHF 010 Design Guide for details. • Enclosure ratings: • IP20 (An IP21/NEMA 1 upgrade kit is available) • IP00 (Forced cooling is required. There is no fan in the IP00 unit. Separate cooling measures must be implemented in the cabinet as part of the installation) VLT® Advanced Harmonic Filter AHF 005 and AHF 010 are robust and easy-to-use passive harmonic filters that reduce harmonics while maintaining good system energy efficiency.
