EMC input filter FLD 3075, 3-phase, class B, for inverters with power 30-37kW FLD3075

EMC Input Filter – Protection and Reliability for Inverters

The EMC input filter FLD 3075 is a key element ensuring electromagnetic compatibility (EMC) in power supply systems for inverters with a power of 30-37 kW. Its task is to eliminate disturbances in the electrical network that can negatively affect the operation of the inverter and other devices. Class B, which this filter falls into, guarantees a high level of interference suppression, meeting safety and compatibility standards.

Application and Benefits

This filter is specifically designed to work with LS Electric inverters, providing an optimal solution for installers and users looking for reliable protection against interference. Using an EMC input filter translates to:

• Increased inverter stability: Reducing interference improves the efficiency and reliability of the device.
• Protection against damage: The filter protects the inverter from overvoltages and other unwanted signals in the power supply network.
• Compliance with EMC standards: Ensures the installation complies with applicable electromagnetic compatibility standards, which is important for safety and legality.
• Reduction of interference emissions: Limits the emission of interference generated by the inverter into the electrical network, minimizing the impact on other devices.

Construction and Mounting

FLD filters are a series of anti-interference filters with high attenuation, designed for operation in three-phase installations up to 480VAC. They are characterized by high effectiveness in suppressing both symmetrical and asymmetrical disturbing currents. The footprint (FF) design allows for easy mounting under the LS Electric inverter, which simplifies installation and ensures an aesthetic appearance. The filter effectively suppresses interference in the frequency range from 150 kHz to 30 MHz, providing optimal protection for the installation. An important aspect is maintaining the correct power supply side of the filter – manufacturers always indicate it to ensure proper device operation.
