This article will discuss the application field and working principle of the FN2450G-20-61 Power Line Filtering Module, a clean energy solution developed by \'X\' for power line network applications. We will begin by discussing the functions of the power line filter, then we will discuss its application field, performance, and finally we will go over its working principle.

Power Line Filter Overview

The FN2450G-20-61 is a power line filter module designed to provide a clean energy solution for applications powered by AC or DC sources. The power line filter helps to reduce electrical noise on the power line by attenuating the high frequency harmonics that are generated by electromagnetic interference from other devices. This reduces the amount of noise interference on the power line, resulting in a more stable and reliable power source for your device and providing enhanced product performance.

Application Field and Performance

The FN2450G-20-61 is suitable for a wide range of applications powered by AC or DC, such as medical electronics, server power supplies, LED lighting, audio systems, and more. It is also suitable for both indoor and outdoor applications due to its IP65 rated enclosure. The power line filter module ensures reliable operation by providing insulation and high-efficiency EMC/EMI suppression up to 50 V/m, with a noise attenuation level of 6 dB or more.

Working Principle

The FN2450G-20-61 power line filter achieves its high noise attenuation level by employing a high-performance T-core inductor assembly. This inductive core structure is composed of external windings, internal windings, and a common flux path. This combination of components creates a multi-stage LC (inductance-capacitance) filter circuit and helps to reduce power-line impedance, ensuring that interference is sharply attenuated while remaining power signals are passed through.

The power line filter module also features two pole technology, which reduces the emission levels of high-frequency harmonics. This is achieved by installing two capacitors in series, with one at each pole, between the input and output ports. This series circuit allows for efficient EMI filtering by optimizing the capacitive reactance and prevents high frequency noise from reaching sensitive electronic devices.

Conclusion

The FN2450G-20-61 Power Line Filtering Module is a high-performance EMI/EMC filter suitable for a variety of power line applications. It provides reliable performance with high levels of insulation and noise attenuation and can be used both indoors and outdoors. It employs a high-performance T-core inductor assembly and two-pole technology to ensure efficient EMI filtering and reduce the all-round emission levels of high-frequency harmonics.
