Power Line Filter Modules

Power line filter modules are components used to reduce the amount of electromagnetic interference (EMI) present in power systems. These modules typically consist of inductors, capacitors and/or resistors that are configured in specific ways. The most commonly used power line filter modules are the NAH-30-101 which are designed to attenuate EMI emitted and conducted by power systems.

Application Field

The NAH-30-101 power line filter module can be used in numerous different applications. Examples include consumer electronics, industrial automation, medical equipment, security systems, and automotive electronics. Additionally, the NAH-30-101 is suitable for use with low-frequency AC power, thereby making it an excellent choice for a wide variety of power sources.

Working Principle

At its core, the NAH-30-101 power line filter module operates on the concept of differential mode filtering, meaning that it is able to reduce the voltage difference between two lines. This is done via capacitive and inductive reactance which is generated by the filter’s components. This reactance essentially reduces the voltage difference between the two power lines while still allowing the line frequency components to pass.

The amount of EMI attenuation provided by a Power line filter module is dependent on the type of filter used, the filter components, and the filter’s configuration. Generally, the higher the frequency of the EMI, the higher the amount of attenuation provided. Additionally, filters configured according to the NAH-30-101 standard have the added benefit of excellent EMC performance as they are designed to meet higher EMC standards.

Conclusion

In conclusion, the NAH-30-101 power line filter module is an excellent choice for applications that require the attenuation of EMI in a reliable and cost-effective manner. This filter is capable of providing excellent attenuation even under high-frequency EMI and has the added benefit of meeting higher EMC standards. Additionally, it is suitable for use with low-frequency AC power, making it well-suited for a wide variety of power sources.
