Power Line Filter Modules

Power line filter modules are devices that are designed to reduce the noise on an electrical line. They can be used in a variety of applications, such as in computers, power supplies, medical electronics, and various industrial applications. The NBH-16-322-D is one such filter module, and it offers a number of benefits in these various applications.

Application Field and Working Principle of NBH-16-322-D

The NBH-16-322-D is a power line filter module designed for noise reduction in multiple-input power supplies. It reduces noise by allowing only desirable frequencies of energy through, while rejecting undesirable frequencies. It is a three-stage filter, and it has two capacitive filters in the first two stages, and a shielded inductor in the third stage.

The first stage of the NBH-16-322-D utilizes a combination of a common-mode choke and two capacitors to filter out frequencies between 7 kHz and 400 kHz. This ensures that the power is free of noise within this range. The second stage consists of two capacitors, one for high-frequency filtering and one for low-frequency filtering. Finally, the third stage incorporates a shielded inductor, which filters out frequencies above 400 kHz. This final stage provides the most complete noise reduction.

The NBH-16-322-D is primarily used in applications that require noise reduction in AC power lines. It can be used in a variety of industries, such as medical, industrial, and consumer electronics. It is particularly well-suited for applications in computer power supplies, as it provides comprehensive noise reduction within the frequencies of interest.

Advantages of NBH-16-322-D

The NBH-16-322-D offers several advantages when used in power line noise reduction. Primarily, it provides noise reduction at a wide range of frequencies, with frequencies up to 400 kHz being reduced. This makes it ideal for power supplies, as it helps to ensure that the supply is free from noise. Additionally, this filter module provides high noise attenuation, which helps devices run reliably in noisy environments. It also helps reduce emissions of high-frequency noise, making it ideal for various industrial applications.

Furthermore, the NBH-16-322-D is designed for multiple-input power supplies and is highly resilient to short-term overloading. It is compact, meaning that it can easily fit into tight spaces, and it also has a low profile, helping it blend into the background and reduce the overall noise in the power supply.

Conclusion

The NBH-16-322-D is a power line filter module designed for noise reduction in multiple-input power supplies. It offers noise reduction up to 400 kHz, and it is highly resilient to short-term overloads. It is also compact and low-profile, meaning that it can fit easily into tight spaces and blend into the background. This makes it ideal for a variety of applications, such as medical, industrial, and consumer electronics. Additionally, its high noise attenuation makes it an excellent choice for reducing noise in a power line.
