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.
