High precision dynamic compensation
Adopting DSP+FPGA fully digital control architecture, real-time tracking and compensation of 2nd to 51st harmonics, with a total harmonic compensation rate of over 95%. For example, in the Jiangyin Port project, the three-phase current distortion rates before treatment were 18.3%, 25.1%, and 32.5%, respectively. After installing the ANAPF series filter cabinet, they decreased to below 2.6%. The ability to control the third harmonic is particularly outstanding, for example, in a certain photovoltaic power station project, the third harmonic current decreased from 109.86A to 3.95A, with a compensation rate of 97%.
A comprehensive solution with multiple capabilities for one machine
Not only focusing on harmonic control, but also synchronously achieving reactive power compensation (power factor increased to 0.99 or above), three-phase imbalance control, and neutral line current suppression. For example, in the Wuxi Henglong Plaza project, the 400A filtering cabinet parallel operation scheme effectively solved the harmonic pollution generated by central air conditioning, elevators and other equipment, while improving the power factor.

Intelligent adaptive adjustment
Equipped with advanced digital signal processing algorithms, it can automatically adjust compensation strategies based on real-time changes in the power grid. For example, in the smart factory scenario, the system can quickly respond to the instantaneous surge current when the equipment starts, ensuring production continuity and reducing equipment failure rates by more than 80%.
Modular design and flexible expansion
Harmonic local compensation device cabinetThe maximum compensation current of a single cabinet can reach 300A (such as ANAPF150-380/BGL models), supporting parallel operation of multiple machines, and the compensation capability can be flexibly expanded by increasing the number of modules. For example, in the Hengqin Port project in Zhuhai, two 60A modules were used in parallel, meeting the high harmonic control requirements of border inspection equipment.
Multi scenario adaptation capability
Centralized governanceSuitable for scenarios such as power distribution rooms, where data centers use ANAPF filtering cabinets to control harmonic voltage distortion rates within 5%.
On site governanceProvide drawer style wall mounted modules (such as ANSNP series) for end loads such as medical equipment and port machinery, with small size and low noise.
New Energy ScenariosIn photovoltaic power plants, combining SVG to achieve millisecond level reactive power response and dynamically compensating for harmonics generated by inverters can improve power generation efficiency by more than 15%.

High reliability and safety protection
Built in bridge arm overcurrent, DC overvoltage, device overheating and other multiple protection functions, and reduce high-frequency ripple interference through output filtering devices. For example, in industrial environments, even in the face of voltage fluctuations or sudden load changes, compensation accuracy and safety can still be maintained
Low loss and high efficiency
The overall efficiency is ≥ 97.5%, the loss is ≤ 2.5%, and imported core components (such as Infineon IGBT) and self-developed technology are used to reduce costs while ensuring performance. For example, after being applied by a cotton spinning enterprise, the comprehensive energy-saving rate of the system increased by about 15%, saving 778200 yuan in electricity bills annually and recovering costs within 3 years.
Long term equipment protection benefits
By suppressing harmonics, additional losses of equipment such as transformers and cables can be reduced, extending their service life. For example, in a hospital project, the issue of excessive neutral current was resolved after treatment, reducing the risk of electrical fires.
Digital operation and maintenance platform
Supports RS485, Modbus protocol, and IoT integration, and can be connected to AcrelEMS energy management platform to achieve remote monitoring, data analysis, and fault warning. For example, in subway projects, real-time monitoring of harmonic data was used to optimize filtering strategies and ensure stable equipment operation
Humanized operation interface
Equipped with a 7-inch color touch screen, it supports parameter settings, real-time waveform display, and historical data query. At the same time, modular design facilitates online maintenance, and replacing faulty modules does not require downtime, significantly reducing operation and maintenance costs
Independent research and development and industry university research cooperation
Breaking the monopoly of foreign technology, having independent and controllable core technologies, and collaborating with universities for development, possessing multiple inventions. For example, the ANAPF series can adapt to various industrial scenarios without resonance with the system through independently developed circuit design and parameter tuning
Strict quality certification
The product has passed international certifications such as CE and ROHS, and complies with domestic standards such as GB/T14549-1993 and DL/T1216-2019. For example, the ANSVG-G-A series has obtained CE certification, ensuring compliance in the global market.
industrial sector
In projects such as Zhuhai Hengqin Port and Jiangyin Port, the current distortion rate was reduced from 12.5% to 4.4% through ANAPF filtering cabinets, ensuring the stable operation of key equipment
Business and Public Facilities
