Import Active Power Filter — Buy in Bulk from Supplier in China

The active power filter from Zhuhai Wanlida Electric Co., Ltd. is a dynamic power electronic device designed to filter harmonics with variable amplitude and frequency while compensating reactive power. It uses a full-bridge PWM converter with 5th generation IGBT modules operating under high-frequency switching, and a master chip combining TI’s F28335 DSP with Altera FPGA for high processing capacity. The system employs a 16-bit AD7606 sampler to ensure control precision, enabling real-time harmonic detection and compensation.

Constructed with a modularized structure, the APF includes a plug-in unit design for ease of maintenance, where same modules can be replaced to enhance reliability. It supports both standalone and hybrid configurations, pairing with passive filters for optimized performance-to-price ratios. The unit features intelligent supervisory control with real-time display of working states and operation parameters, self-diagnosis for faults, and remote communication interfaces for PC-based monitoring.

This active power filter is suitable for industrial applications such as static converters, DC equipment, ferrous and non-ferrous rolling mills, electrolysis, rubber and plastic machinery, medium-frequency induction furnaces, electroplating, paper production, petrochemistry, and DC traction equipment. It is also used in high-precision production lines to reduce harmonic interference. The product is packaged in a fumigated wooden case for export.

Zhuhai Wanlida Electric Co., Ltd. is based in the High-Tech Zone of Zhuhai, Guangdong, China, with its address at Relay Protection Industrial Park, No.1 Technology Road. The company operates within the imported supplier tier and specializes in power electronic equipment, including active power filters for industrial harmonic mitigation and reactive power compensation.
