The 690V Cabinet-Type Active Harmonic Filter (APF) offers a robust solution for harmonic mitigation and power quality enhancement in 690V three-phase three-wire and four-wire electrical systems. This APF utilises advanced DSP+CPLD digital control and a three-level topology for precise harmonic current compensation up to the 50th harmonic, simultaneously correcting three-phase imbalances. The modular design supports scalable capacity by enabling parallel connection of multiple units. Housed in a durable cabinet with independent air ducts, the 690V Cabinet-Type Active Harmonic Filter ensures reliable performance and simplified maintenance. With available current ratings up to 300A and kvar capacities up to 300, this APF delivers effective power quality improvement for 690V systems.

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.
Applications:
690V Cabinet-Type Active Harmonic Filters are ideal for improving power quality in medium-voltage industrial settings:
● Medium-Voltage Power Systems: Stabilising power distribution in 690V networks, reducing harmonic distortion and improving system efficiency.
● Heavy Industrial Environments: Ensuring reliable operation of sensitive equipment in industries with significant harmonic loads, such as mining, oil and gas, and petrochemicals.
● Medium-Voltage Motor Drives: Minimising harmonic currents generated by large motor drives, reducing voltage distortion and improving motor performance.
● Marine and Offshore Platforms: Providing stable and reliable power quality in harsh environments where 690V systems are common.
690V Cabinet-Type Active Harmonic Filters provide a high-performance solution for optimising power quality in demanding 690V applications.
