Advanced Harmonic Filter AHF
Advanced Harmonic Filters (AHF) are power quality solutions designed to mitigate harmonic distortion in electrical networks, typically rated for currents from 6 A to 600 A and voltages up to 690 V AC.

Advanced Harmonic Filters (AHF) are power quality solutions designed to mitigate harmonic distortion in electrical networks, typically rated for currents from 6 A to 600 A and voltages up to 690 V AC. These filters actively cancel harmonics generated by non-linear loads such as variable frequency drives (VFDs), rectifiers, and UPS systems, ensuring compliance with IEEE 519 or IEC 61000-2-4 standards. They are available in 3-phase configurations (3P or 3P+N) and feature fast dynamic response times below 100 µs, with optional built-in reactors or passive damping circuits. In the industry, they are also known as active harmonic conditioners, power quality filters, or harmonic compensators.
These filters are deployed in industrial automation panels, commercial building distribution boards, and critical infrastructure like data centers or hospitals. They protect sensitive equipment from voltage distortion, reduce transformer and cable overheating, and improve overall system efficiency. Common applications include water treatment plants, HVAC systems, manufacturing lines, and renewable energy installations where power factor correction and harmonic mitigation are essential.
Our catalog includes subcategories such as wall-mounted AHF units (e.g., model series AHF-006 to AHF-600), modular rack systems, and integrated filter-drive combos. Key article codes follow a pattern like AHF-XXX-YYY, where XXX denotes rated current in amps and YYY indicates voltage class (e.g., 400 or 690). For example, AHF-100-400 represents a 100 A filter for 400 V networks. We also stock accessories like remote monitoring modules and bypass switches.
