Power Line Filter Modules

The FN3270H-150-99 power line filter module is a device designed to reduce electromagnetic interference (EMI) between electrical devices connected to the same power source. It is a combination of passive components, inductors and capacitors, designed to filter out undesirable frequencies that could fragment transmitted signals. The module provides EMI protection at multiple frequencies and does not require external components such as fuses and diode bridges.

Applications

The FN3270H-150-99 power line filter module is commonly used in applications where high-quality filtering is required. These include power line communications, industrial automation, data networks, and automotive applications. It is particularly useful in reducing external EMI for systems used in critical applications, such as medical instruments or military equipment. It is also used to reduce the amount of electromagnetic radiation emitted by other sources, and can be used to protect sensitive electronic components from damage due to over-voltage or over-current.

Working Principle

The FN3270H-150-99 module is designed to filter frequencies in the range of 150 kHz to 320 kHz. The module consists of two printed circuit boards (PCBs) sandwiched together. On the top board, resistors and capacitors form the EMC filter network. The inductor coils are placed on the bottom board. The inductors and capacitors act as low-pass filters, blocking high frequency EMI while allowing lower frequencies to pass through. The resistors, capacitors and inductors are connected in a circuit to provide an impedance path for EMI. This helps reduce the level of EMI generated in the power line. The FN3270H-150-99 module is designed to meet the requirements of the European EMC Directive 89/336/EEC, and is CE-marked for compliance. The module also meets the requirements of EN55022 for electromagnetic emissions and EN55024 for immunity. The filter module is tested and approved to EN60950-1 standards for safety of information technology equipment.

Conclusion

The FN3270H-150-99 power line filter module is a highly effective device for reducing EMI in electronic systems. It is compact and cost-effective, and is designed to meet stringent EMC standards. This filter module is suitable for use in industrial automation, medical instruments, military equipment, and other sensitive electronic components.
