Power Line Filter Modules are devices that are specifically designed to help protect electrical appliances as well as any other long-distance power transmission cables from electrical surges or spikes that may cause them to fail. One such popular power line filter unit is B84144A0008R140. Its applications and working principles will be further discussed in the following sections.

Applications

B84144A0008R140 is a three line filter module that designed by EPCOS, a leading supplier of power line filter modules. As suggested by its name, this device has three filter lines, making it a suitable solution for the protection of various three-phase devices. Moreover, the supplier stipulates that this device is suitable for the protection of electronic equipment, electronic equipment with motor drives, electronic equipment with high power back-up modes, such as servers, as well as other industrial applications.

It is true that this power line filter module can be connected to the system in some specific ways. To begin with, the module can be directly mounted onto the application as it has some special fastening elements that have been integrated onto the device. It can also be mounted onto a PCB board, and is connected to the system using screw terminals that have been integrated into the device.

It also offers technical advantages in the form of an integrated EMI filter, a built-in surge arrester, and an EMC filter that is built into the system. All these features ensure that the module is well-suited for all kinds of powers protection applications, and that it is able to filter out any harmful electromagnetic interference that may come from the outside environment.

Working Principle

As far as the working principle of B84144A0008R140 is concerned, it must be understood that this module is designed to work by providing noise filtering capabilities. This is achieved by allowing the filtered signal to be passed through the filter while blocking out interference signals.

In order to do this, the power line filter module uses its unique capacitance coupled line filter. This line filter is composed of three series capacitors, and the connection of these three capacitors form current loops that are able to filter out the noise. This line filter helps to prevent the propagation of EMI (electromagnetic interference) as well as surges, which can ultimately lead to the failure of the devices.

Furthermore, it should be noted that this module also employs attenuator for provide additional EMI protection. This is done by removing the low-frequency signals before the line filter takes effect. The line filter itself then helps to further attenuate the remaining EMI.

B84144A0008R140 is a highly effective and reliable power line filter module that is designed for the protection of three-phase devices, electric motor drives, and servers. Its capacitance coupled line filter helps to filter out any interference signals as well as provides noise filtering capabilities, while its attenuator ensures additional EMI protection.
