Power Line Filter Modules: B84312C40H1 Application Field and Working Principle

The B84312C40H1 is a three-phase power line filter module used to suppress conducted electromagnetic interference (EMI). The module is designed to reduce any form of EMI that might interfere with the operation of connected equipment. This includes any noise that arises from electrostatic discharge (ESD), lightning strikes, or conducted RF (radio frequency). The B84312C40H1 module is the most popular EMI suppression device used in consumer and industrial applications.

This power line filter module is designed with several components such as impedance capacitors, π-filters, X-filters, and inductors. These components are connected in series and/or in parallel to reduce noise along the path of the power line. The B84312C40H1 is primarily targeted for single-phase application and they can be used in any type of electrical installation, such as in lighting fixtures, heating and cooling systems, motor controls, and office equipment.

The single or three-phase power line filter module is typically used to suppress interference within the lines or cables. It helps protect against any form of electromagnetic interference, including interference from radio signals, power supplies, electrical equipment, etc. It also helps reduce any noise generated in the power line. The module is ideal for industrial applications, such as in motors, pumps, instruments, and other electronic devices.

When the power is applied to the module, the capacitors and inductors connected in a series/parallel arrangement contribute to reduce the impedance of the line. The reduction in impedance increases the noise-reduction rate of the line. This will reduce any EMI signals from entering into the line. Also, the module will also prevent any kind of leakage of current back into the line.

Additionally, the B84312C40H1 utilizes a bypass capacitor to reduce the rate of transient over-voltages along the power line. The bypass capacitor helps reduce the rate of voltage transients that can cause disturbances in the operation of connected equipment. This module can withstand surges and spikes up to 1500V peak to peak and 6KV impulse surge.

The B84312C40H1 is a highly efficient EMI filter module that provides excellent performance in terms of noise reduction in the power line. It is highly reliable and requires minimum maintenance. The filter module is used widely in the industrial sector where higher levels of electronics are used and EMI is more of a concern.
