Introduction

Power Line Filter Modules have become essential components in voltage transformers and other power applications. This paper will discuss the application fields and the working principle of a particular module, NAM-10-331-DXE.

Application Fields

NAM-10-331-DXE is mainly used in power supply applications such as transformer systems, rectifiers, DC converters, switch-mode power supplies and other AC/DC power supplies. It can be used to filter out high-frequency noise and transients. It is designed to mitigate electrical noise and interference generated by switching circuits.

Structure and Design Considerations

NAM-10-331-DXE is composed of common-mode inductors and capacitors. It is designed to filter out noise, transients and interference from the power line, while maintaining an appropriate DC voltage level.The module includes external shielded windings, which help to reduce electromagnetic interference (EMI) and radio frequency interference (RFI). Additionally, the module has temperature sensing and gas discharge tubes (GDT) for over-voltage protection. The module is designed to be used in low-voltage, high-current applications, and can be used in both single and three-phase power supplies.

Working Principle

The working principle of NAM-10-331-DXE is based on its structure. The common-mode inductors are used to suppress noise and transients on the AC power line. The inductors act as a low-pass filter, and the capacitors act as a high-pass filter. The inductors create an impedance path for high frequency noise, which reduces the amount of noise that reaches the output. The capacitors, on the other hand, reduce the amount of low frequency noise by forming a series resonance with the inductors. The combination of the two components helps to reduce the total amount of noise on the power line, allowing a cleaner DC output.The shielded windings help to reduce the amount of EMI and RFI entering the power path, and the GDTs provide protection in the event of overvoltage.

Conclusion

NAM-10-331-DXE is a suitable choice for power supply applications that require filtering and over-voltage protection. Its combination of common-mode inductors and capacitors, shielded windings and GDTs, makes it an effective solution for power line filtering. Additionally, its compact design allows it to be used in both single and three-phase power supplies.
