DC fans are popular cooling solutions for a range of applications and they continue to become more and more commonplace as their cost and availability improve. The 109R0812L4D011 DC fan is a reliable and efficient cooling solution for a wide variety of applications. This article will discuss the application field and working principle of the 109R0812L4D011 DC fan.

The 109R0812L4D011 DC fan is an axial fan designed for cooling of applications that use a DC voltage source. It has a plastic frame and impeller, and the motor is rated for dc voltages ranging from 6 to 12 volts. This fan is typically used in applications such as power supplies, video game consoles, medical equipment, and computers. It can also be used in larger applications, such as air conditioners, refrigerators, and other larger household appliances.

The 109R0812L4D011 DC fan has a relatively consistent airflow and high static pressure. It has a maximum airflow of 53.4 cubic feet per minute (CFM) and static pressure of 1.44 inH2O. The fan can operate up to a maximum speed of 4,300 revolutions per minute (RPM), and the starting voltage is around 6 volts. The motor in the DC fan has a life expectancy of 100,000 hours at a 25°C ambient temperature.

The working principle of the 109R0812L4D011 DC fan utilizes an electric motor to turn the fan axle and blades. This is done by a DC current that flows through the motor, thus producing motion. As the axle and blades rotate, the airflow rate increases, cooling the components of the application. As the fan blades rotate faster, the static pressure increases, allowing the fan to move air through more restrictive passages. This increased static pressure allows the fan to do its job more efficiently.

The DC fan is also equipped with a speed control selection system which allows users to select the desired fan speed setting. The speed control selection system is a knob located at the back of the fan and is used to select the desired fan speed. Depending on the application, users can select from low, medium, and high settings. This speed control selection system also includes a power-up, power-down control circuit which allows for the fan’s speed to slowly ramp up or ramp down which helps to reduce in-rush current and motor noise.

The 109R0812L4D011 DC fan is a reliable and efficient cooling solution for a wide variety of applications. It is able to operate up to a maximum speed of 4,300 RPM, and has a life expectancy of 100,000 hours. Its speed control selection system allows users to choose from three different speed settings depending on the application. This fan is suitable for cooling applications that use a DC voltage source, and is an excellent choice for many applications.
