Common Mode Chokes (CMC) are devices used to suppress noise and harmonics in power lines and motor drives. DLW 21SN 181XQ2L is one of the most common types of CMC, designed for the purpose of proactive harmonic suppression. It is widely used in a variety of industries and applications, including motor drives, robotics, automation, power transmission, and energy storage.
Working Principle
At its core, the DLW 21SN 181XQ2L is composed of two specially designed inductors. These inductors each have an impedance that is designed to match the load at a specified frequency. As the current flows through the inductor, a magnetic field is produced. This magnetic field then induces a “back emf” across the inductor, which is a counter-voltage that opposes the input current. By having these two inductors connected in series and with their impedances properly matched, spikes and harmonics in the power lines can be effectively suppressed.
Application Fields
Due to its highly efficient suppression of high-frequency noise and harmonics, the DLW 21SN 181XQ2L is a popular choice for many industries, applications, and solutions. It is extensively used in motor drives for both form and frequency modulation. Additionally, it is often used in robotics, automation, and power transmission in various industries including automotive, aerospace, and railroad. Furthermore, it is also used in energy storage systems for dampening leakage fields and improving efficiency.
Overall, the DLW 21SN 181XQ2L is one of the most reliable and most widely used types of CMC, thanks to its effective noise and harmonic suppression capabilities and its wide range of industrial applications. It is a highly sought after choice for many industries and applications, and its reliability and efficiency have made it one of the most popular types of CMC in the market.
