Your Reliable Power Quality Filter Manufacturer in China
Nengdu is a high-tech and “Specialized, Sophisticated, Unique and New” enterprise focusing on power quality management and the research and development of new energy technologies. The company mainly deals in core products such as active power filters, static var generators, and power quality filters, and owns a number of patents and software copyrights. Its products are widely used in general industry, new energy grid connection, rail transit, data centers, power grid distribution, and other fields, which can effectively solve comprehensive power quality problems, including three-phase imbalance, harmonic pollution, and insufficient reactive power.
As an advanced power electronic device, the Power Quality Filter (PQF) samples grid and load currents in real time, uses a high-speed DSP to separate harmonics, reactive power, and unbalanced components, and generates compensating currents with equal amplitude and opposite phase to cancel such disturbances, thus purifying the grid current and ensuring the grid stability and equipment protection.

Modular Design of Our Power Quality Filter
The power quality filter features a professional modular design, usually consisting of one or more filter modules and an optional LCD touch screen. Adopting full digital control and power electronic topology, it detects and cancels grid harmonics in real time, while simultaneously providing reactive power compensation and three-phase unbalance mitigation. It purifies electric energy from the source, ensures a safe and stable power supply, and solves power quality problems such as harmonic heating, equipment maloperation, capacitor resonance, and metering deviation.
It can eliminate harmonic interference, reduce equipment heating, prevent malfunctions, avoid capacitor resonance, and improve metering accuracy.
Three models are provided: floor-standing, rack-mounted and wall-mounted, to meet different space installation requirements.
Yes, the equipment supports multimodule parallel connection, and the compensation capacity can be increased by adding modules directly.
Easy installation, flexible configuration and convenient maintenance, with high reliability and stability.
