The Power Line Filter Module EAP-20-681 is designed for use in industrial and commercial markets, and is capable of filtering high frequency components from DC power lines. This module offers superior performance in noise and EMI protection, and is used to eliminate unwanted and potentially disruptive EMI signals that would otherwise interfere with the system’s operation or performance. It is also useful for suppressing noise in power circuits and protecting them from external high frequency interference.

In addition to filtering high frequency components, the EAP-20-681 is also capable of protecting AC lines from electrical disturbances, such as transient voltage variations. It is equipped with a MOV (Metal Oxide Varistor) for this purpose, which helps to reduce or eliminate any voltage overstresses in the system. In addition, the EAP-20-681 is capable of providing a low-pass filter to eliminate high frequency noise from entering the DC supply line.

The EAP-20-681 is made up of four core components: a common mode choke, leakage inductor, epoxy cast module, and an MOV. The common mode choke reduces transient high-frequency noise, while the epoxy cast module and leakage inductor filter out the low frequency power line noise. The MOV helps to clamp any incoming voltage, providing protection from electrical disturbances and transients.

The working principle of the EAP-20-681 is based on what is known as inductive reactance. This is an electrical phenomenon which describes how the resistance to the current growth changes with frequency. The EAP-20-681 uses this principle in order to create a low-pass filter which helps to eliminate high frequency noise and other interference from entering the power line.

In addition to providing superior noise protection and time-variance protection, the EAP-20-681 is also capable of providing superior safety protection, thanks to its thermal protection feature. This feature helps to reduce the impedance of the filter module in order to protect the system from overcurrent or short circuit. The thermal protection feature helps to reduce the risk of fires due to excessive currents, as it will automatically reduce the impedance of the filter module when the current exceeds a certain level.

The EAP-20-681 is a reliable and cost-effective Power Line Filter Module that provides superior noise and EMI protection, as well as AC line protection from transients and electrical disturbances. It offers an excellent solution for commercial and industrial applications, and is particularly useful for controlling high frequency noise from entering power circuits. Thanks to its thermal protection feature, it also provides superior safety protection, helping to reduce the risk of fires caused by excessive currents.
