Power Line Filter Modules

Power Line Filter Modules, such as the NBM-20-000-D, are required in many types of electrical systems requiring reliable, constant power supply. By the use of a filter network, connected between input and output, unwanted noise and waveshape distortion from the power source are effectively contained. In addition, the filter can also serve a number of other functions, such as protecting against high voltage with a current limiter or protecting sensitive equipment from electromagnetic interference.

The NBM-20-000-D Power Line Filter Module is typically used in large, industrial applications, such as electric motor control and other electronic control systems. It has a nominal current rating of 20 amps and a maximum voltage rating of 30V DC. It is designed to withstand severe electrical and thermal stresses, making it suitable for applications in both commercial and military applications. The NBM-20-000-D was designed to meet MIL-SPEC requirements for power line filters.

The NBM-20-000-D Power Line Filter Module works by providing a low pass filtering effect, which removes wide-frequency noise and reduces the amplitude of high frequency noise. This is accomplished by connecting capacitors in series between the input and output stages, which act as a low resistance path for the DC signal to pass through and also provide an impediment to any EMI/RFI. Additionally, the NBM-20-000-D includes inductors in series, which both limit the current draw and reduce high frequency noise. The total filtering effect of the NBM-20-000-D also helps to reduce EMI/RFI and electromagnetic interference.

Furthermore, the NBM-20-000-D filter can also act as a high voltage protection device, as it can protect against overvoltage by limiting the current draw. This is done by utilizing an overvoltage protection circuit, which monitors the input voltage and shuts off the power supply if it exceeds the set limits.

Finally, NBM-20-000-D Power Line Filters also provide transient, lightning and surge protection, due to the internal components acting as a surge arrestor. These components help to reduce the effects of lightning and surges on the power supply, making the system more reliable and secure.

In conclusion, the NBM-20-000-D Power Line Filter Module is an invaluable component for anyone that requires reliable power and noise free operation. With its range of features, such as low pass filtering, overvoltage protection, transient and surge protection, it is well suited to a variety of large, industrial applications.
