Common Mode Chokes are widely used in industrial applications, for various reasons. They are often used to reduce interference, to improve power quality, to reduce harmonics, or to improve signal integrity in communications applications. The FE2X27-4-2 is a common mode choke designed specifically for use in industrial applications. This article will take a look at the application field and working principle of this product.

The FE2X27-4-2 is designed to be used in various industrial applications, such as industrial control systems, electric instrumentation, electrical switchgear, and AC/DC power transmission systems. In these applications, the FE2X27-4-2 acts as an inductor, reducing the parasitic capacitance in parallel with the DC power range. It also serves as an electromagnetic interference (EMI) filter, blocking any high frequency harmonics from reaching the connected circuit.

The working principle of the FE2X27-4-2 is simple. It consists of two windings, one primary and one secondary. When an alternating current (AC) signal is applied to the primary winding, a magnetic field is created. This field induces the currents in the secondary winding, creating a voltage. This voltage is then used to block high frequency harmonics from reaching the connected circuit, effectively serving as an EMI filter.

In addition, the FE2X27-4-2 is also used to reduce radiative emissions from power lines. This is because the induced voltage in the secondary winding creates a magnetic field, which acts as an effective shield against the emissions. As a result, the FE2X27-4-2 is a popular choice for industrial applications that need to meet emission standards.

The FE2X27-4-2 is also used to reduce the amount of interference created in the power line due to the common mode noise generated by power sources in equipment. As already discussed, this noise is effectively blocked by the induced voltage in the secondary winding of the choke, as it acts as an EMI filter. As a result, the power line is insulated from any undesirable interference.

The FE2X27-4-2 is a popular choice among industrial control systems due to its efficient and reliable performance. It has a wide frequency range, from 50 kHz to 300 kHz, allowing it to block a wide range of harmonics. Additionally, the magnetic field created by the FE2X27-4-2 is strong enough to reduce the parasitic capacitance of up to 350 pF. This greatly reduces the transmission of transients on the power line, leading to improved power quality.

Overall, the FE2X27-4-2 is a versatile and reliable common mode choke, designed for industrial applications. It works by creating a magnetic field, which induces a voltage in the secondary winding. This voltage is then used to block high frequency harmonics, reducing emissions from the power line and improving power quality. Additionally, the FE2X27-4-2 has a wide frequency range and strong magnetic field, making it an ideal choice for various industrial applications.
