Input filter FEE 3120, 3-phase, class A FEE3120

Input filter – inverter protection and interference reduction

The FEE 3120 input filter is a key element ensuring the correct operation and reliability of inverters and drive systems. Designed for operation in 3-phase installations, it effectively suppresses electromagnetic interference (EMC), protecting both the inverter itself and other devices in the network. The filter's Class A rating guarantees a high level of interference reduction, meeting the requirements of modern electromagnetic compatibility standards.

Application and benefits

Filters from the FEE series, including model 3120, are widely used in industrial installations where the presence of inverters generates interference affecting the operation of other devices. Installing an input filter minimizes these negative effects, ensuring stable and safe system operation. This makes it possible to avoid problems with incorrect readings, communication interference, or damage to sensitive components. The FEE 3120 filter is particularly recommended for use with inverters with a power of 45-55 kW, where filtration efficiency is crucial.

Construction and installation

FEE filters are characterized by a solid construction and high quality of workmanship. They are designed to ensure reliable operation even in harsh industrial conditions. Filter installation is simple and intuitive, which translates to saving time and installation costs. It is important to select the correct filter for a specific application and inverter power – the FEE 3120 model is dedicated to devices with a power of 45-55 kW and a rated current of 120A. This ensures optimal protection against interference and long-term reliability of the entire system.
