FN520-12-29

Power Line Filter Modules

FN520-12-29 is a series of power line filter modules manufactured by Fuji Electric. It has a wide range of applications especially in circuit designs for commercial and industrial systems, and its working principle is related to the fundamentals of current and voltage isolation.

Applications

FN520-12-29 filter modules are suitable for various kinds of circuit and system designs. Common applications may include controlling noise caused by electromagnetic disturbances, eliminating switching noise generated by computers and other electronic devices, and improving isolated power supplies. Special attention should be paid when used in medical systems, as it can reduce the shock hazard to medical equipment and protect its components from voltage transients.

Working Principle

The FN520-12-29 filter module works in accordance with the fundamentals of current and voltage isolation. It is designed with two types of inductors: the common mode inductor and the differential mode inductor. The common mode inductor is used to block common-mode noise propagation, while the differential mode inductor can effectively intercept differential-mode noise propagation. Besides inductors, the filter module also relies on capacitors to reduce the high frequency noise components generated by the switching power devices.

The working principal of the FN520-12-29 filter module is primarily dependent on the interactions of the inductors and capacitors. The common mode inductor prevents the high frequency common-mode noise from propagating, while the differential mode inductor prevents the high frequency differential mode voltage from propagating. The capacitors also eliminate high frequency noise components present in the sources.

Conclusion

The FN520-12-29 filter module is a versatile and reliable solution for reducing noise in a wide range of circuit and system designs. Its working principle is related to the fundamentals of current and voltage isolation, and relies on the interactions between inductors and capacitors to reduce noise components. The FN520-12-29 makes it possible to control electro-magnetic disturbances, eliminate switching noises, and improve isolated power supplies, making it suitable for a variety of applications.
