EMC input filter FLD 3007, 3-phase, class B, for inverter power 0.4-3kW FLD3007

EMC input filter – protection and installation compatibility

The EMC FLD 3007 input filter is a key element ensuring electromagnetic compatibility (EMC) in power supply installations for inverters. Its task is to eliminate disturbances in the electrical network that can negatively affect the operation of other devices or cause problems with measurements. Thanks to its design, this filter suppresses both symmetrical and asymmetrical components of disturbing currents, minimizing the emission of disturbances into the network.

This Class B three-phase filter is dedicated to inverters with a power of 0.4 kW to 3 kW. This means it effectively protects the installation against disturbances generated by these devices, ensuring their stable and reliable operation. Class B indicates a high level of disturbance suppression, meeting the requirements of electromagnetic compatibility standards.

Construction and application

EMC filters, such as the FLD 3007, work by eliminating unwanted frequencies from the electrical signal. Insertion loss – a parameter determining the effectiveness of filtering – is crucial for ensuring optimal protection. In the case of disturbances in the frequency range of 150 kHz to 30 MHz, RFI (Radio Frequency Interference) filters are necessary to meet the standards regarding emission of disturbances.

The FLD 3007 filter belongs to the footprint type filter series (FF), which means it has been designed with easy mounting under LS Electric inverters in mind. This solution simplifies installation and ensures an aesthetic appearance of the installation. These types of filters are particularly important in industrial applications where high reliability and minimization of electromagnetic interference are required.
