The 690V Rack Mount Active Harmonic Filter (AHF) provides advanced harmonic mitigation for high-voltage (690V ±20%) three-phase power systems. This rack-mounted unit utilises a DSP+CPLD digital control core and three-level topology for precise harmonic compensation up to the 50th harmonic. With a 100A rated current capacity, it effectively addresses harmonic distortion and three-phase imbalance. The modular design supports parallel connection for increased capacity and simplified maintenance. Forced air cooling ensures reliable operation. The 690V Rack Mount Active Harmonic Filter delivers robust power quality management for demanding industrial environments.
● 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.
Applications:
690V Rack Mount Active Harmonic Filters are crucial for maintaining power quality and equipment performance in high-voltage power systems:
● Heavy Industrial Applications: Mitigating harmonics produced by large variable frequency drives (VFDs), rectifiers, and other non-linear loads in high-voltage systems.
● Mining and Oil & Gas: Ensuring reliable operation of critical equipment in harsh environments with high-voltage power distribution.
● Renewable Energy Integration: Stabilising power from high-voltage renewable energy sources connected to the grid.
● Data Centres and Critical Infrastructure: Protecting sensitive equipment and maintaining power quality in high-voltage data centre environments.
690V Rack Mount Active Harmonic Filters offer effective harmonic mitigation for enhanced power quality in high-voltage applications.
