Ideal for commercial buildings, industrial, medical facilities and residential applications.
The Single-Phase Cabinet-Type Active Harmonic Filter (APF) offers a robust solution for harmonic mitigation in single-phase power systems. Utilising a DSP+CPLD digital control core and advanced filtering algorithms, this cabinet-type APF effectively reduces harmonic currents up to the 50th order. Its modular design allows for flexible capacity expansion through parallel connection. The APF features a robust cabinet enclosure and forced-air cooling for reliable operation in demanding environments. With a range of available models and capacities, the Single-Phase Cabinet-Type Active Harmonic Filter provides effective power quality improvement for various applications.
Model description:
| GY | APF | 0.4 | 50A | / | 4L | C |
| Enterprise code | Active Harmonic Filter |
Voltage level 0.22:220V |
Rated Capacity（kvar） 25A | 2L:Single-phase | C:Cabinet |
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:
Single-Phase Cabinet-Type Active Harmonic Filters address harmonic distortion challenges across various sectors:
● Commercial Buildings: Mitigating harmonics from single-phase loads such as lighting, HVAC systems, and office equipment.
● Industrial Facilities: Improving power quality for single-phase equipment and processes in industrial settings.
● Medical Facilities: Protecting sensitive medical equipment from harmonic distortion in single-phase power systems.
● Residential Applications (High-Power): Addressing harmonic issues in homes with significant single-phase non-linear loads.
Single-Phase Cabinet-Type Active Harmonic Filters provide targeted harmonic mitigation, ensuring optimal power quality for single-phase applications.
