DC Fans

DC fans are an essential part of any electronic cooling or air-conditioning system, providing an efficient and cost-effective way to move large volumes of air. The most common type of DC fan is a brushless DC (BLDC) fan, which utilises an electronically-controlled motor to operate the fan blades. In this article, we will look at the features and working principles of the 9G1248E1011 DC fan, and discuss the application fields in which this particular type of fan is particularly suited.

What is the 9G1248E1011 DC Fan?

The 9G1248E1011 is a high-performance DC fan designed for a variety of cooling and air-conditioning applications. This type of fan is equipped with a powerful brushless motor that operates the fan blades with a high degree of efficiency, while its low power consumption ensures maximum operating time. This particular fan is also UL/CE/RoHS compliant and has a built-in thermal protection system that prevents it from overheating.

Features and Specifications of the 9G1248E1011 DC Fan

The 9G1248E1011 features a highly-efficient brushless motor capable of providing a maximum airflow of 78.5 CFM at a static pressure of 0.41 inch H2O, a maximum speed of 5.3 CFM at an ambient temperature of 25C, and a maximum input current of 0.68A. It also has a noise level of 28dBA, making it suitable for quieter applications. The fan is rated for a long life of up to 30,000 hours, and it comes with a 10-year manufacturer’s warranty.

Applications for the 9G1248E1011 DC Fan

Due to its excellent performance and reliability, the 9G1248E1011 is a popular choice for a wide range of cooling and air-conditioning applications. It can be used in computers, servers, medical and laboratory equipment, industrial controls, and other critical applications where efficient cooling is required. The fan is also suitable for applications that require low noise and long life, such as computer cooling fans, lab equipment, and medical devices. Additionally, its fully-sealed environment-resistant construction makes it well-suited for demanding industrial applications.

Working Principle of the 9G1248E1011 DC Fan

The 9G1248E1011 utilises a brushless DC motor to turn the fan blades. A brushless DC motor is a type of electric motor that uses permanent magnets instead of brushes to transfer power from the external supply to the motor. As the magnets rotate past each other, the electric current is generated, which in turn drives the motor and produces rotation of the fan blades. The permanent magnets also enable the motor to run extremely quietly and efficiently, ensuring optimal performance.

Conclusion

The 9G1248E1011 DC fan is an efficient and cost-effective solution for a variety of cooling and air-conditioning applications. It has a powerful brushless motor and a sealed environment-resistant construction, making it ideal for industrial applications. Additionally, its low power consumption and long life make it a reliable choice for critical systems. With all of these features, the 9G1248E1011 is perfect for those looking to improve the efficiency and performance of their cooling and air-conditioning systems.
