Power line filter modules have been widely used in industrial automation, civilian applications and communication networks. FN2080-3-07 series power line filter is a well known brand, which is widely used for its wide application field and good interference attenuation characteristics. The working principle of FN2080-3-07 power line filter module will be discussed in this passage.

FN2080-3-07 Application Field

The FN2080-3-07 series power line filter has a wide application field, including AC/DC, DC/DC, AC/AC, DC/AC and other power conversion applications, such as solar energy power generation, wind power generation, uninterruptible power supply (UPS) system, audio power amplifier, computer server, telecommunication system, medical instrument, home appliance, and other industrial applications.

FN2080-3-07 Working Principle

The FN2080-3-07 series power line filter is composed of three parts: the common mode inductor, the differential noise filter, and the transient interference suppression circuit. To achieve good EMC performance, the three parts need to work together. In the common mode, the common mode inductor realizes the purpose of common mode noise suppression by working together with the differential noise filter and the transient noise suppression circuit. In the differential mode, the differential mode inductor and the filter capacitor form a LC resonance, which works as a high-order low-pass filter network, thus having a good differential noise suppression effect.

Meanwhile, the transient noise suppression circuit in the power line filter module can absorb transient PLC harmonics and transient high-level interference signals, thus having an interference suppression effect. The spectrum parameter design and output link of the filter module is based on the environmental conditions of the application system, in order to adapt to different levels of interference.

Conclusion

To conclude, the FN2080-3-07 series power line filter module is broadly used for its wide application field and good interference attenuation characteristics. It is composed of three parts: the common mode inductor, the differential noise filter, and the transient interference suppression circuit. The power line filter module can absorb transient PLC harmonics and transient high-level interference signals, thus having an interference suppression effect.
