The ESP-06-331 power line filter module is a highly reliable and functional line filter for power management applications, providing components with added protection from high voltage disturbances. This module is designed to ensure that the power system is safe and reliable for long-term use. It is composed of a single-phase 3-terminal filter module with a high-frequency 80mA SMA coaxial internal capacitor, and a low-frequency 32A SMA coaxial internal inductor.

Features of ESP-06-331 Power Line Filter Module

• High line capacity: maximum continuous output power can reach 200W;
• Excellent filtering performance: meet EMI, RFI and SMPTE requirements;
• Low distortion: when operated at 50Hz, the distortion is less than 0.01%;
• High efficiency: more than 95%;
• Long service life: more than 5 years.

Working Principle of ESP-06-331 Power Line Filter Module

The ESP-06-331 power line filter module works on the principle of differentiating high and low frequencies. By separating signals into high and low frequencies, it filters out high frequency signals that can cause noise and interference. This separation is accomplished using two separate SMA coaxial capacitors and inductors. The capacitors act as a low-pass filter for the large voltage components, while the inductors act as a high-pass filter for the high frequency components.

When the power line is connected with the ESP-06-331 power line filter module, the filter will first enable the current ripple frequency component around the filter. Then the capacitors and inductors of the module will filter the low frequency signals, i.e., they will pass signal components with frequencies lower than their cut-off frequency, and block signal components with frequencies higher than their cut-off frequency. In this way, the module completely blocks high frequency signals and allows the current ripple frequency component to remain in the power line.

Application Field of ESP-06-331 Power Line Filter Module

The ESP-06-331 power line filter module is suitable for all kinds of single-phase power supply and power output applications. It is widely used in various electronic systems, such as industrial power supplies, medical equipment, telecommunication systems, central air-conditioning systems, power distributing cabinets, power strips, audio equipment, etc. By filtering out the high frequency signal, it can eliminate the vibration noise, improve the power quality and ensure that the equipment connected to the power line will not be affected by the electromagnetic interference (EMI) disturbances or voltage surges.

In addition, the module can also be used to protect against over-current surges. The ESP-06-331 power line filter module features a current limiting function, which limits the peak current to a specified value and reduces the impact of spikes and over-currents on the system. The module has a wide temperature range and is suitable for use in harsh environments, which makes it a reliable component for long-term applications.
