DC fans, which are powered directly by the DC power supply, are widely used nowadays in communications, electronics, industrial machinery and other fields. This article will focus on the 5920PL-04W-B39-D00 fan and its application field and the working principle behind it.

The 5920PL-04W-B39-D00 fan is a compact, low-noise fan with a diameter of 60mm, a height of 25mm and a weight of around 70g. It has a great air flow rate of at least 48.5 CFM and a static pressure of up to 2.1 mm-H2O at a maximum speed of 6,000 rpm. This fan also has a starting voltage of approximately 5.0 V, and it provides a high level of efficiency, which helps to reduce power consumption.The fan is designed for various applications such as personal computer cases, consumer electronics, industrial machinery, network switches and other applications.

The 5920PL-04W-B39-D00 fan is a brushless DC fan, which is driven by a four-wire system made up of two wires for the power supply and two wires for the sensor signal. During operation, the power supply synchronizes the current flowing to the hub motor. The sensor, on the other hand, offers feedback on the speed of the motor through a signal sent to the circuit board. The speed of the fan is then adjusted in order to achieve the desired performance level.

The four-wire system is the key feature that makes the 5920PL-04W-B39-D00 fan so reliable. The power transistor is connected in an H-bridge configuration, which allows the drive voltage to be adjusted based on the feedback from the sensor, resulting in a constant and reliable speed. This four-wire system also helps to reduce noise because it eliminates the need for a resonant capacitor, which is known to generate a buzzing noise.

In addition to its efficient and reliable performance, the 5920PL-04W-B39-D00 fan is also designed with a “focal height” design, which ensures that air is drawn evenly from the bottom of the fan to the top. This unique design helps to maximize the efficiency of cooling and minimize vibration and noise levels. It also has an impeller with nine blades that is optimized to reduce airflow turbulence and minimize noise.

The 5920PL-04W-B39-D00 fan is an excellent choice for applications that require a low-noise, reliable fan. Its four-wire system offers precise control over the power supply and the speed of the fan, which helps to reduce noise and improve efficiency. The optimized impeller design and the “focal height” design helps to reduce noise and maximize the cooling efficiency of the fan, making it an ideal choice for applications where a reliable, low-noise fan is required.
