MBS-1220-22

Power line filter modules are essential components found in both home and industrial applications. These types of filter modules can help reduce or eliminate transient signals, commonly known as electromagnetic interference (EMI). The MBS-1220-22 is an industrial power line filter module used to suppress EMI in a variety of applications. This article will discuss the application field and working principle of the MBS-1220-22 filter module.

The MBS-1220-22 power line filter module is typically used in moderate power Electronics applications. It is suitable for input voltage of 500V AC/DC and an operating frequency of up to 50 Hz. It is especially useful in AC/DC power supplies, as it can reduce the overhead time required to design, build, and debug the power supply components. In addition, it is an effective tool for eliminating line noise from high speed electric drives.

The MBS-1220-22 power line filter module works by passing the operating frequency through a combination of filter stages. Each filter stage is specifically designed to reduce or eliminate interference from other electrical devices. The filter module has three separate filters for higher frequency harmonics, lower frequency harmonics, and common-mode noise. These filters account for higher frequency noise, lower frequency noise, and noise in the same signal, respectively.

The higher frequency filter stage is designed to provide noise-suppression for frequencies above 25 kHz, which are known to cause interference in small signal applications such as ringing or buzzing sounds. The lower frequency filter stage is designed to ensure minimal insertion loss at frequencies up to 1 KHz and also provides high-frequency linearity for drives and inverters.

The common-mode noise filter is designed to reduce the negative effects of common-mode noise on the system. Common-mode noise is induced in the AC/DC power line, and can cause the system to operate at an incorrect voltage or even fail. The filter module also has active components that provide EMC protection, which helps protect the system from other sources of EMI.

The MBS-1220-22 power line filter module is an effective tool for reducing or eliminating transient signals, such as EMI, in a variety of applications. Its combination of filters ensures minimal insertion loss, high-frequency linearity, and EMC protection. Additionally, its working principle is well-suited for use in high-speed electric drives and AC/DC power supplies. Thus, the MBS-1220-22 is an excellent choice for industrial applications where EMI reduction is necessary.
