The Three-phase three-wire Wall-mounted Active Harmonic Filter (APF) dynamically mitigates harmonic currents, improving power quality in three-phase systems. This wall-mounted unit utilises advanced DSP+CPLD digital control and a three-level topology for precise harmonic compensation. It offers a wide filtering range (2nd to 50th harmonics), high filtering efficiency (up to 95%), and fast response time (<10ms). Modular design allows for scalable solutions through parallel connection. The filter also addresses three-phase imbalances and includes comprehensive protection features. Available in various current ratings (25A to 150A) and voltage levels (220V to 690V).

| Enterprise code | Active Harmonic Filter |
Voltage level 0.22:220V 0.4:380V±20% 0.5:500V±20% 0.69:690V±20% |
Rated Capacity（kvar） 25/50/75 /100/150A | 3L:Three-phase three-wire | W:Wall-mounted |
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:
Three-phase three-wire Wall-mounted Active Harmonic Filters are ideal for various applications requiring precise harmonic mitigation:
● Data Centres: Protecting sensitive equipment from harmonic
distortion.
● Hospitals: Ensuring reliable power for critical medical
devices.
● Industrial Environments: Improving power quality in
manufacturing processes, including petrochemical, pharmaceutical, steel, and
semiconductor industries.
● Textiles and Light Industry: Enhancing efficiency and
reducing harmonic-related issues in textile and light industrial settings.
● Renewable Energy Systems: Integrating renewable energy
sources while maintaining grid stability.
Three-phase three-wire Wall-mounted Active Harmonic Filters offer a compact and effective solution for optimising power quality in diverse applications.
