Power line filter modules have been increasingly popular in many different industries in recent years, due to their exceptional performance, dependability, and affordability. ESP-10-331 is the latest in a long line of these power line filter modules and is especially designed for DC/AC applications. This article will discuss the typical application fields, working principle, and features of the ESP-10-331.

Application fields

The ESP-10-331 power line filter module is designed to protect sensitive electronic devices from high-frequency interference, surges, and spikes that can cause costly damage. Typical applications may include but are not limited to medical equipment, industrial automation, telecom equipment, and home appliances. The ESP-10-331 provides a wide frequency range of 150 kHz to 150 MHz, allowing filtering of a variety of frequencies. Moreover, the ESP-10-331 is compliant with FCC Class B requirements, helping to ensure it matches the needs of different applications.

Working Principle

The ESP-10-331 is a 3-phase power line filter module that filters the high-frequency signal from the power grid. It is composed of symmetrical high-Q inductors and capacitors configured in an EMC chamber. When a signal is applied, the high-frequency signal is shunted to the EMC chamber, where the inductors and capacitors act as a low-pass filter, attenuating the energy of the signal. This reduces the noise generated by the power grid, protecting the integrity of sensitive electronic components.

Moreover, the ESP-10-331 is designed with efficient bypass diodes to protect the system from voltage spikes or surges. When the system is exposed to a surge of up to 10 kV, the diode will open, redirecting the energy away from the sensitive components and effectively protecting the system. This feature is very useful for industrial and automotive applications, where surges and spikes from the electrical power sources can cause damage.

Features

The ESP-10-331 offers a broad range of features that make it the ideal choice for many industrial and automotive applications. It features a compact case size with a plug and play design, allowing for easy installation and setup. Additionally, the ESP-10-331 is designed with an embedded EMI shield, allowing it to conform to strict standards of electromagnetic compatibility. This ensures that the device will perform to specifications even when exposed to electromagnetic interference from other sources.

The ESP-10-331 also comes with LED indicators, allowing for quick troubleshooting when the device is not functioning as expected. On top of this, the ESP-10-331 is designed with an adjustable input voltage range of 25 to 265VAC. This makes it perfectly suited for many different applications, no matter the voltage range of the power source.

Finally, the ESP-10-331 also features a high insertion loss of up to 68 dB, ensuring an extremely low noise level. This ensures that the noise from the power grid will not be a cause for concern, allowing for smooth and uninterrupted operation.

In conclusion, the ESP-10-331 power line filter module is an ideal choice for many industrial and automotive applications. It offers protection from high-frequency interference, surges, and spikes, while still having a broad frequency range of 150 kHz to 150 MHz. Its efficient bypass diodes, LED indicators, and adjustable input voltage range make it a truly versatile product. With its exceptional performance, dependability, and affordability, it is no wonder that the ESP-10-331 is a popular choice among many.
