AC Fans are widely applied in different industries. The 109S478UL-20, a self-starting AC fan, is one of the most commonly used fans in various applications. It is a light, compact and versatile fan, suitable for cooling of a wide range of electronic components. In this article, we will discuss the 109S478UL-20’s application field and working principle.

Application Field

The 109S478UL-20 fan can be used in a wide range of applications. It is widely used in general electronic cooling applications, such as automobiles, computers, control systems, outdoor equipment, PCs, projectors, telecommunications devices, etc. It is also suitable for the cooling of communications equipment, kiosks, digital signage, and other media outlets. Moreover, it is also suitable for cooling space-limited areas, such as server racks, medical equipment, HVAC systems, and other industrial applications. Furthermore, it can be used in small scale applications, such as handheld devices and medical equipment.

Working Principle

The 109S478UL-20 is a self-starting AC fan, meaning it starts and runs without additional starting hardware. This type of fan uses a split-phase induction motor, which consists of a stator and a rotor. When the voltage is applied to the stator, the electric current induces a rotating magnetic field. The attractive and repulsive forces between the stator and the rotor cause the rotor to rotate at a given speed. The speed can be adjusted by changing the voltage input or frequency.

The AC fan also includes its own electrical circuit and power supply. The electrical circuit is used to control the speed of the fan, as well as the torque and current, allowing the user to adjust the fan’s output in order to achieve optimal cooling performance. Furthermore, the power supply provides the power necessary for the fan’s operation.

In addition, the fan also includes several other features. It is designed to be energy efficient and reliable, capable of operating in extreme temperatures and producing a low amount of noise. Furthermore, due to its low profile design, the fan is able to fit into tight spaces, making it suitable for space-limited applications. Additionally, it has an integrated thermal cut-off switch, which automatically shuts off the fan when it reaches a certain temperature.

Conclusion

The 109S478UL-20 self-starting AC fan is a versatile, energy efficient, and reliable fan, suitable for a wide range of applications. Its application field includes cooling in automobiles, computers, control systems, outdoor equipment, PCs, projectors, telecommunications devices, communications equipment, kiosks, digital signage, server racks, medical equipment, and HVAC systems. In addition, its working principle includes a split-phase induction motor, electrical circuit, and power supply. All of these features make the 109S478UL-20 an ideal choice for cooling applications.
