EMC input filter FLD 3180, 3-phase, class B, for inverters with power 75-90kW FLD3180

EMC input filter – protection and reliability in installations with inverters

The FLD series EMC input filter is a key element ensuring electromagnetic compatibility (EMC) in power supply installations with inverters. Model FLD 3180, designed for devices with a power of 75-90kW, effectively suppresses interference, protecting both the inverter itself and the other elements of the system. The class B in which the filter is classified guarantees a high level of noise and interference reduction.

This three-phase network filter is designed to operate at a voltage of up to 480 VAC and is characterized by high efficiency in suppressing both symmetrical and asymmetrical disturbances. This minimizes the impact of interference generated by the inverter on the power supply network and protects it from interference coming from the network. A low leakage current value further increases safety.

The "book-type" construction of the FLD 3180 filter facilitates installation and ensures effective heat dissipation. The use of screw terminals guarantees solid electrical connections. This filter is dedicated to use with long power cables, up to 50 meters in length, which provides flexibility in installation design.

Applications and benefits

The FLD 3180 EMC filter is widely used in industrial installations, especially where inverters, drive systems and power supplies are used. Its installation allows for:

• Ensuring compliance with electromagnetic compatibility (EMC) standards, including EN 50081-2 and EN 50081-1.
• Reducing interference generated by the inverter, minimizing its impact on other devices on the network.
• Protecting the inverter from interference coming from the power supply network, increasing its reliability and lifespan.
• Simplifying installation thanks to the compact "book-type" construction and easy mounting.
• Increased safety thanks to the low leakage current value.
• Possibility of using with long power cables without fear of deterioration of filtering parameters.

The FLD 3180 filter is an investment in stable and reliable operation of devices, as well as in protecting the entire electrical installation from the negative impact of electromagnetic interference. Its solid construction and high quality of workmanship guarantee long-term operation even in demanding industrial conditions.
