Power Line Filter Modules are electronic components used for reducing electromagnetic interference (EMI) from electric devices and systems. In order to accomplish this, the modules are designed to reduce conducted emissions and noise generated by power lines. FN2080-6-06 is a type of power line filter module developed by FN Feirlitz Company and is tailored specifically for applications in medical equipment. This article discusses the applications in which FN2080-6-06 can be used in and its working principle.

The FN2080-6-06 is ideal for use on medical equipment powered by batteries or AC mains. Its primary purpose is to minimize conducted interference produced by power lines. The filtered output of the module is very low, ranging from 0.1-0.2V, so it is well-suited for biomedical applications. In addition, the module also provides a high filter attenuation of up to 16dB across the entire frequency range of 10-1000MHz, which is an ideal requirement for medical devices. Moreover, the module has a metal case and is equipped with non-brushed, non-etching output contacts.

In order to understand how the FN2080-6-06 works, it is important to understand what is called “ground-loops.” A ground-loop is an electrical circuit composed of the AC mains power supply, a chassis ground wiring, and a power cable. The power cable is the connecting line between the equipment and the power source. Ground-loops are undesirable and can cause higher than acceptable levels of conducted interference. However, by utilizing a power line filter module such as the FN2080-6-06 in the circuit, this interference can be minimized.

The FN2080-6-06 works by introducing a three-phase circuit between the common-mode and differential-mode currents. This circuit is usually implemented in what is called a “tau filter” configuration. This circuit’s purpose is to reduce the amplitude of any conducted interference on a power line. In addition, the tau filter blocks the following frequencies: 10-560KHz, 900-1100MHz, and 10-1000MHz. Therefore, any conducted interference generated between the specified frequencies is blocked by the filter, providing the user with improved noise immunity.

In conclusion, the FN2080-6-06 is a power line filter module designed specifically for use in medical equipment. Its primary purpose is to reduce conducted interference generated by power lines, and it is well-suited for biomedical applications due to its low filter output. Additionally, the module utilizes a tau filter to minimize any conducted interference generated between specified frequencies. Therefore, the FN2080-6-06 is a useful tool for reducing noise and providing improved immunity for medical equipment.
