When you need to effectively control the electromagnetic interference generated by variable frequency drives (VFDs), our DF2 three-phase EMI filters are an ideal solution.
The DF2 EMI filter is installed at the input of the variable frequency drive (VFD) system to suppress electromagnetic interference emi and radio frequency interference (RFI) from the power supply. The DF2 series filters are designed with single polarity and are specifically designed for VFD applications. They can effectively suppress high-frequency noise and interference signals in the power line to ensure system stability and reliability.
The filter uses a combination of high frequency inductors and capacitors as essential components to reduce noise and manage high frequencies (150 kHz to 30 MHz), ensuring compliance with EMC standards. The rated current range of the filter is 15A to 50A, the rated voltage is 440VAC, and flexible customization options are provided to meet the needs of specific applications, including different load and power supply requirements.

The DF2 three-phase EMI filter significantly improves power quality, reduces electromagnetic interference (EMI) to downstream equipment, and improves overall system performance. To ensure optimal filtering effectiveness, proper grounding, low-impedance, high-frequency ground connections, and high-quality cables should be used to minimize electrical noise and conducted interference.
This filter is particularly suitable for industrial automation, mechanical drives, and electrical control systems, effectively protecting sensitive equipment from EMI issues, data transmission errors, high-speed switching, PWM signals, and conducted/coupled noise. It is designed to stabilize output voltage, improve output power quality, and reduce radiation risks, ensuring clean and reliable power to the load.
With its low leakage current, the DF2 filter not only meets safety and regulatory requirements in industrial environments, but also significantly reduces the risk of interference with other equipment. Improper installation or excessive ripple can degrade filtering performance, impacting system output.
Whether designing new equipment or upgrading existing systems, the DF2 three-phase EMI filter provides an efficient and stable electromagnetic compatibility (EMC) solution, helping you achieve better power management and maintain compatibility with a wide range of industrial and electrical equipment.
