Input filter FEE 3080, 3-phase, class A FEE3080

Input filter – inverter protection and interference reduction

The FEE 3080 input filter is a key element ensuring proper operation and reliability of inverters and drive systems. Its main task is to suppress electromagnetic interference (EMI), which can negatively affect device operation and cause electromagnetic compatibility problems. This Class A filter is designed to work with inverters with a power of 30 to 37 kW, making it an ideal solution for a wide range of industrial applications.

Design and application

Anti-interference filters from the FEE series, including model 3080, are effective in eliminating unwanted signal components. They operate by suppressing interference in the frequency range from 150 kHz to 30 MHz, ensuring compliance with applicable standards. The filter design takes into account both the symmetrical and asymmetrical components of disturbing currents, which translates into high filtration efficiency. An important aspect is also the “reciprocity” of the filter – its equal effectiveness in suppressing in both directions of energy flow.

The FEE 3080 filter is primarily used in:

• Inverters (frequency converters)
• Drive systems
• Power supplies
• Industrial installations requiring reduction of electromagnetic interference.

Advantages and benefits

• Effective EMC interference reduction: Ensures stable device operation and minimizes the risk of interference in the power supply network.
• Inverter protection: Protects the inverter from damage caused by overvoltages and interference.
• Compliance with standards: Meets the requirements for electromagnetic compatibility, which is important for the safety and proper operation of the installation.
• High quality workmanship: Guarantees filter reliability and long service life.
• Optimal power selection: Adapted to work with inverters with a power of 30-37 kW, which ensures effective filtering of interference without unnecessary energy losses.
• Class A: Indicates higher interference suppression efficiency compared to Class B filters, which is particularly important in demanding industrial applications.

FEE anti-interference filters are an economical solution meeting high requirements for electromagnetic interference suppression, and the FEE 3080 model is particularly recommended for higher power applications.
