The 690V Wall-mounted Active Harmonic Filter (AHF) offers high-performance harmonic mitigation for three-phase 690V power systems. Employing a DSP+CPLD digital control core and three-level topology, this AHF ensures accurate harmonic current compensation. Its modular design supports scalable installations through parallel connection, simplifying maintenance and optimising space. The 690V Wall-mounted AHF effectively filters harmonics from the 2nd to 50th order, achieving up to a 95% filtering rate. With a 100A rated current and dimensions of 495mm x 675mm x 275mm (DWH), this wall-mounted unit provides robust power quality solutions for high-voltage industrial environments.

Features:
● Use DSP+CPLD all digital control core, three-level topology technology, advanced harmonic detection algorithm and PWM control strategy to achieve accurate compensation of harmonic current.
● Adopt modular design, which facilitates parallel connection of multiple modules, takes up little space and is easy to maintain.
● The structural design of independent air ducts and independent warehouses ensures the stable operation of the equipment.
● It can filter harmonics in a wide range of harmonics, from 2 to 50 harmonics, and solve the problem of three-phase unbalance at the same time.
● The harmonic filtering rate is high. If the capacity allows, the harmonic current filtering rate can be as high as 95%. Set 100% current limiting output to ensure long-term stable operation of the equipment.
