DC Fans

DC fans are electrical fans that are powered with direct current (DC) power. They are typically used to cool electronic components or machines such as computers, servers, and other electronic systems. DC fans have several advantages over AC fans in that they are more energy efficient, have lower noise levels, and are more resistant to dust and dirt. Furthermore, they are more reliable and can be used in applications where space is limited.

One example of a DC fan is the UF383-100. It is a lightweight fan designed for cooling applications in computer systems, consumer products, and off-the-shelf enclosures. The fan has a wide operating voltage range of 8 to 24 VDC, making it suitable for use with a variety of DC power sources. It is also equipped with a tachometer output, allowing it to be used in applications where precise speed control is required. The UF383-100 features a low-noise, two ball-bearing design that provides reliable and quiet operation over its rated life of 80,000 hours.

Application Field

The UF383-100 is designed for cooling a variety of electronic components and systems. It is suitable for use in applications where space is limited, such as off-the-shelf enclosures, medical instrumentation, and communications systems. It can also be used in fan tray assemblies to provide cooling for server racks, computer systems, and other high-performance electronics. Other potential applications include automotive, instrumentation, and industrial control systems.

Working Principle

The working principle of a DC fan is fairly simple. When power is applied to the fan, the blades of the fan rotate, causing air to be drawn in at the front of the fan and pushed out at the back. This creates a cooling effect as the air passes over the components and systems it is cooling. The speed of the fan is determined by the voltage that is supplied to it, with higher voltages resulting in faster speeds. The fan also features a tachometer output that allows for precise speed control.

Conclusion

The UF383-100 is a DC fan designed for cooling a variety of electronic components and systems. It features a wide operating voltage range, low-noise two ball-bearing design, and tachometer output for precise speed control. The fan is suitable for cooling applications in computer systems, consumer products, and off-the-shelf enclosures, as well as applications such as medical instrumentation, communications systems, fan tray assemblies, and automotive, instrumentation, and industrial control systems. The fan operates on the principle of rotation, with power supplied to the fan blades, causing them to rotate and draw in air, creating a cooling effect.
