Power Line Filter Modules play an important role in the power system, and the NBM-20-471-Dis a common type of such module. This module is used for suppressing differential mode currentand interfere components such as high frequency noise. It also has two types of structure: axially andradially symmetric. So, what is the application field and working principle of NBM-20-471-D?

In terms of application field, The NBM-20-471-D is commonly used in Industrial, Military andAeronautic fields where high noise interference and differential current can occur. For instance, thismodule can be used in various motors as adjustable speed drives, wind turbines, HVAC systems andother electromechanical systems. Also, it can be used in communication systems such as mobilephones and cordless telephones.

As for the working principle, NBM-20-471-D adopts three-stage parallel Filter structure which iscomposed of inductors, capacitors and resistors. It works by using the principle of magnetic fieldcoupling and electric shielding to block the interference components. Firstly, the inductors create amagnetic field that prevents differentials current and high frequency noise from entering the circuit. Secondly, the capacitors act as a filter to prevent contact noise between the two circuits. Thirdly, theresistor filter further reduces the high frequency components. All of this ensures good voltageregulating capability and low impedance.

In conclusion, The NBM-20-471-D Power Line Filter Module is widely used in various industrial,military and aeronautic fields. Its working principle based on three-stage parallel Filter structure canprovide effective protection against differentials current and high frequency noise, as well as remarkablevoltage regulating capability and low impedance.
