Introduction to DC Fans

A DC fan, or an “electric fan” is a type of cooling device which uses a direct current (DC) motor to move air across its blades and dissipate heat generated by the device. DC fans are used to regulate temperature within electronic and electrical equipment, as well as to safely reduce the risk of fire or damage to components. They are widely used in computers, audio/video equipment, industrial applications, telecommunications equipment and medical equipment.

The 1204KL-01W-B30-B00

The 1204KL-01W-B30-B00 DC fan is a reliable and efficient fan designed to provide powerful cooling with a low noise level. It is a four-wire brushed motor DC fan with a dual ball bearing and a tachometer. The fan has a wide operating temperature range of –10 to +70°C, and a speed of 3200rpm. It is UL, TUV approvals and RoHS compliant.

Application Field

The 1204KL-01W-B30-B00 is a versatile DC fan, well-suited to both commercial and industrial applications. It is a popular choice for cooling computer components, such as power supplies, fan trays, CPUs, controllers and memory cards. The fan is also used in the telecommunications, medical, and audio/video industries, as well as in industrial equipment.

Working Principle

DC fans work by drawing air into the fan’s inlet port and pushing it out through the fan’s outlet port. This is accomplished by a motor that is connected to two aligned fan blades which rotate and draw air in through the inlet and expel air through the outlet. The motor is specifically designed to deliver consistent air flow across both blades. The motor also generates a static pressure, which is the difference between the inlet and outlet pressures.

At the heart of the 1204KL-01W-B30-B00 is a permanent magnetic DC motor with a dual ball bearing for smoother, quieter operation. The motor’s internal magnets are energized in sequence by the fan’s four-wire tachometer. This sequentially energizes the motor’s north and south poles, thereby creating a rotational movement. As the fan blades rotate, air is drawn into the fan inlet and expelled out through the fan\'s outlet. The fan uses the energy from the motor to create a static pressure which is necessary to ensure a consistent air flow.

Advantages of the 1204KL-01W-B30-B00 DC Fan

The 1204KL-01W-B30-B00 DC fan offers several advantages over traditional AC fans. Firstly, it does not require the complex and expensive circuitry associated with AC fans and the installation and maintenance of AC fans is much more difficult than with DC fans. Secondly, DC fans are extremely efficient and have low operating temperatures, making them much quieter and more reliable. Finally, DC fans offer a much wider range of accessories, including speed control options, temperature sensors, tachometers and thermistors, which make them suitable for a variety of different applications.

Conclusion

The 1204KL-01W-B30-B00 DC fan is a reliable and efficient fan with a wide application field. It offers low noise levels and wide operating temperature ranges, making it a popular choice for a variety of different applications. Additionally, it does not require the complex and expensive circuitry associated with AC fans and offers a range of accessories for further customization. It is UL, TUV approvals and RoHS compliant and is a reliable choice for any DC fan installation.
