FM3MMB1015MLUDA Application Field and Working Principle

FM3MMB1015MLUDA is a type of three-phase power line filter developed by Fluk, which belongs to MMB series of new generation of internal electrostatic shield protection filter with excellent filtering performance, slim body structure and small load current. Moreover, Compared to conventional power line filters, it has greatly improved performance and can effectively suppress high-frequency noise in various types of power load and improve the system\'s electromagnetic compatibility (EMC).

Application Field

FM3MMB1015MLUDA is mainly used in distribution technology for filtering, noise suppression and power line network decoupling in industrial, civil and other occasions. It can be used to filter main lines, motor lines, rectifier 9 lines, digital computer and other peripheral lines. It is suitable for high voltage, sudden current, frequent lightning strikes, very harsh and high pollution areas, and has unparalleled advantages in terms of protection performance, current overload and persistent filtering suppression. It is widely used in mechanical equipment, elevators, inverters, medical equipment, banking equipment, electronic equipment, electrical and other industries.

Working Principle

FM3MMB1015MLUDA is mainly composed of inductor, capacitor, interference source and line impedance. It uses interference attenuation and kinetic inductance to filter the interference signal. The inductor and capacitor form an L-C filter, and the filter cooperates with the line impedance to form a LC resonance loop, so as to suppress high-frequency noise.The noise current is diverted to the ground, while the useful current continues to flow through the line, thus forming a filter circuit. The three-phase filter has 3 inductors and 6 capacitors. They form 6 channels in series and parallel for the three-phase circuit. The direction of the inductor is very important. The middle point of the inductor is the ground through which the interference flows, and its opposite has the same direction. The current of these two directions will add vectorially, so that the interference can be better contaminated to the ground, and further reduce the conducted interference of the equipment.

Conclusion

FM3MMB1015MLUDA power line filter has advanced structure, safety, reliability and high performance in filtering and suppressing noise. The union of inductor and capacitor forms LC filter to filter the interference signal, and the filter can cooperate with the line impedance to form a LC resonance loop, so as to achieve the effect of high-frequency noise suppression. It is widely used in mechanical equipment, elevators, inverters, medical equipment, banking equipment, electronic equipment and other industries.
