Introduction

Power line filter modules, such as 3VK7M, provide a wide range of electrical performances ranging from static electricity protection to power protection of electrical equipment. The most common application of 3VK7M includes protection of relay and protection from high voltage spikes. The sine wave filter, as a line filter module, is used to protect power lines and connected equipment from high frequency noise. It is also designed to suppress radio frequency interference and protect sensitive electronic circuits from EMI.

Purpose

The main purpose of 3VK7M is to protect various electrical appliances from surge and power line interference. It is designed to provide protection against transient over-voltage, transient or disruptive noises, and radio frequency interference. With a maximum operation frequency of 40 MHz, 3VK7M can be used for a variety of applications such as EMI suppression, data transmission, audio/video signal transmission, and servo control.

Features

The most notable feature of 3VK7M is its frequency response. This line filter module has a low-frequency response of up to 30 MHz and a high-frequency response of up to 40 MHz, allowing it to effectively filter out high-frequency noise. In addition, its 300 VAC input voltage is reliable for both commercial and industrial applications. Its response time is also very fast, providing immediate protection for connected equipment during electrical disturbances. Finally, its temperature range of -25℃ to +85℃ indicates it is suitable to be used in harsh environment.

Applications

The 3VK7M is used to protect industrial and consumer electronics in a variety of applications. It can be found in EMI filter systems, electronic circuits, server rooms, and data centers. In addition, it is widely used to protect telecommunications and audio/video equipment, home electrical appliances, computers, meters, and other sensitive equipment.

Working Principle

The 3VK7M line filter module utilizes high frequency filtering technology to suppress and absorb noise in both power and data lines. It has two components, the power line filter and EMI filter. The power line filter traps and attenuates high frequency noise, while the EMI filter blocks and attenuates RF interference. It is also designed to ground and protect the connected circuit from transient over-voltage and noise caused by lightning, electromagnetic fields, etc.

Conclusion

In conclusion, 3VK7M is a power line filter module with a wide range of applications in consumer and industrial electronics. It is capable of suppressing high-frequency noise and EMI, and filtering out RF interference. Its temperature range and response time make it suitable for harsh environment applications, while its low-frequency and high-frequency response make it a reliable power line protection choice.
