The EAP-03-472-D power line filter module is designed to reduce electrical noise, transient voltage, and transient current on power lines. This module helps protect electronic circuits and systems from being damaged by interference from outside sources, such as other signals on the power lines. The module is also used in data conversion and signal conditioning applications.

The EAP-03-472-D power line filter module is a fully encapsulated filter, making it particularly suitable for high-voltage applications. This module is rated at up to 428Vrms and has an impedance of 4700 ohms. It is capable of filtering AC and DC supplies up to 7A.

The filter module consists of three main components: a multi-layer capacitive filter, a metalised film inductor, and a thermal switch. The capacitive filter is responsible for filtering out high frequencies, while the metalised film inductor is used to reduce low frequency interference. The thermal switch helps ensure the safety of the modules by limiting the current and power levels.

The EAP-03-472-D power line filter module is primarily used in applications where power line noise is particularly high. Examples include medical electronic equipment, power supplies, telecommunications equipment, and industrial automation systems. The filter module is designed to meet the criteria of the industrial and medical safety standards, ensuring a high degree of safety and reliability.

The working principle of the EAP-03-472-D power line filter module is based on the capacitive interference suppression (CIS) technique. This technology involves the electrical separation of the noise generator (power line) and the sensitive loads connected to the power line. The capacitive filter forms an impedance between the power line and the sensitive loads, which helps to reduce the interference from the power line. The metalised film inductor reduces the low frequency interference, while the thermal switch limits the current and power levels.

The EAP-03-472-D power line filter module is a reliable and cost-effective solution for reducing power line interference in sensitive electronic systems and applications. It is easy to install and provides a high degree of protection from interference. The module is also designed to meet the industrial safety standards, ensuring a high level of reliability and safety.
