Power line filter modules are essential components of electronic circuits designed to reduce interference on power lines and protect connected equipment and appliances from voltage spikes and other disturbances. The FTA-80-223-H is a power line filter module produced specifically for applications where cost savings must be achieved while maintaining performance to eliminate line noise.

This module has two three-phase 380V AC connections, allowing it to handle higher currents and lower surge protection ratings than most filter modules. The module also offers impressive protection against both conducted and radiated EMI noise on the power lines. The connection terminals are designed to meet all known cylinder, box, and rail standard mounting requirements, ensuring a secure connection to the application.

The FTA-80-223-H is designed with a three-section symmetrical filter structure that specifically targets line interference. The first section features three ceramic capacitors that are connected in series to create a high-pass filter, providing considerable protection against common-mode interference. The second section is a differential-mode filter, which is designed to suppress interference caused by the load current on the line. Finally, the last section is an inductor designed to keep the differential-mode filter signal within the desired line frequency range.

The working principle of the FTA-80-223-H is simple. When line noise is detected, it is first filtered out by the high-pass filter in the module. This removes the largest portion of interference and allows the remaining noise to be handled by the differential-mode filter. This filter then prevents the remaining interference from escalating and reaching the electronics or appliance being protected by the filter. Finally, the inductor ensures that the differential-mode filter can remain effective at the desired frequency range, thus providing the highest level of protection.

Overall, the FTA-80-223-H is an excellent choice for applications looking for a cost-effective solution that can reduce line interference. It employs a three-section symmetrical filter structure to ensure the greatest amount of public watts are removed. With its high surge protection rating, wide application field, and secure connection terminals, the FTA-80-223-H is an ideal module for high-powered industrial applications.
