AHF – Active Harmonic Filter
Sinexcel AHF – Reliable Harmonic Compensation for Industrial and Commercial Applications
The Sinexcel AHF active harmonic filter is a modern shunt-connected device designed for dynamic compensation of harmonic currents in three-phase electrical networks. Utilizing an advanced FFT algorithm, it monitors current in real time and injects a compensation current with opposite phase, effectively eliminating harmonic distortion from the 2nd to the 50th order.
The Sinexcel AHF product range offers a wide current capacity from 25 A to 300 A and supports voltage levels of 220 V, 400 V, 480 V, 600 V, and 690 V. This makes it a universal solution for most industrial and commercial installations across the Czech Republic and Europe.
Why Do You Need an Active Harmonic Filter?
Modern industrial and commercial facilities are filled with non-linear loads: variable frequency drives (VFDs), UPS systems, LED lighting, welding machines, and rectifiers generate harmonic currents that cause overheating of cables, transformers, and motors, increase energy losses, and may lead to failures of sensitive electronic equipment.
The Sinexcel AHF active harmonic filter addresses these issues dynamically. Unlike passive filters, it adapts to changing load conditions, eliminates the risk of resonance, and simultaneously provides power factor correction.
