3-phase Class A input filter FEE 3036 FEE3036

3-Phase Input Filter – Protection and Reliability of the Installation

The FEE 3036 input filter is a key element ensuring effective reduction of electromagnetic interference in power supplies for inverters and drive systems. Designed to operate in 3-phase networks, it offers high damping efficiency, protecting both the inverter itself and other devices connected to the network. Its use translates to more stable device operation and minimizes the risk of failures caused by interference.

Application and Benefits

Anti-interference filters from the FEE series, to which the 3036 model belongs, are particularly recommended for use with inverters with a power of 15 to 18.5 kW. They ensure compliance with electromagnetic compatibility (EMC) standards, which is important in modern industrial and commercial installations. By reducing interference, the FEE 3036 filter affects:

• Increased system reliability: Protection against interference minimizes the risk of malfunction of the inverter and devices connected to it.
• Improved power quality: Reduction of harmonics and other disturbances contributes to voltage stabilization in the network.
• Meeting EMC standards requirements: Ensuring compliance with applicable safety and compatibility standards.
• Protection against damage: The filter protects sensitive components of the inverter from overvoltages and other anomalies in the power supply network.

Construction and Parameters

FEE 3036 is a Class A filter, which means high damping efficiency for both symmetrical and asymmetrical interference. The filter design is based on high-quality components, which guarantees its durability and reliability even in harsh working conditions. The filter's rated current is 36A, making it an ideal solution for inverters of a specific power. This filter is designed to operate in power supply networks with a voltage of up to 480V AC.

It is worth remembering that anti-interference filters work by eliminating unwanted components of the electrical signal, improving its quality and stability. Insertion loss – a parameter characterizing the filtering efficiency – is crucial for ensuring optimal installation protection.
