DC Fans Overview

DC fans are a type of fan used to cool electronic components. The fans are powered by direct current (DC) and feature low noise levels, making them an ideal choice for applications where noise levels must be kept to a minimum. They are also more efficient than traditional AC fans, providing greater airflow at lower power consumption.

4710KL-05W-B20-L00 Application Field and Working Principle

The 4710KL-05W-B20-L00 is a low-noise DC fan specifically designed for use in applications that require a high degree of cooling power but also need to keep noise levels to a minimum. The fan has a 5-wire power connection, including a red, black, blue, yellow, and white wire. The red and black wires are for power, the blue is for speed sense, the yellow is for power sense, and the white is for tachometer.The fan\'s working principle is based on the Bernoulli principle, which states that an increase in the velocity of a fluid will lead to a decrease in its pressure. In the case of the 4710KL-05W-B20-L00, an increase in the fan\'s speed leads to an increase in its cooling power. The fan can be set to run at three different speeds: low, medium, and high.DC fans have many applications, including computer and server racks, indoor air conditioning units, and consumer electronics. In addition, DC fans are a popular choice for industrial and commercial ventilation systems. They are also used in medical equipment, such as MRI and CT scanners.The 4710KL-05W-B20-L00 is an ultra-quiet DC fan that is capable of providing high cooling power with minimal noise levels. It is designed for a wide range of applications, and it is a reliable and efficient choice for applications where noise levels must be kept to a minimum.
