DC Fans, also known as DC brushless fans, are relatively new to the cooling fan market. From the name, it is assumed that they are driven by a DC voltage source; however, the fans are in fact driven by an internal DC motor. The 9GV1248J101 is a type of DC fan offering a low noise level and high reliability for cooling applications.

The 9GV1248J101 features an ultra-thin design, measuring 48x48x12mm, enabling it to fit into compact spaces. It has a superior airflow rating of 40.5CFM, allowing it to cool high powered components easily. Its rated speed is 4200 rpm, and the rated voltage is 12VDC.

The 9GV1248J101 offers quiet operation with its low noise rating of 34.7dB. It also has a long lifespan of over 60,000 hours, ensuring reliable performance in any demanding application. Additionally, the fan features PWM control, which allows users to adjust the speed to the optimal level for their specific application.

The 9GV1248J101 features a dual-ball bearing, providing exceptional long-term durability. It also offers an output power of 2.4W, allowing it to cool high powered components efficiently.

The 9GV1248J101 is perfect for any computer or consumer electronics applications where cooling is essential. It is also suitable for industrial and telecom applications that require high reliability.

The working principle of the 9GV1248J101 is based on the principle of the DC motor. The DC motor works with a set of magnets attached to the stator or the outer casing of the fan. When the current is applied to the motor, the magnets cause the rotor to rotate, which causes the blades of the fan to move, thus creating an airflow.

The fan can be controlled using the PWM feature of the motor. The speed of the fan is controlled by the PWM signal; as the PWM duty cycle increases, the speed of the fan increases. The motor also features thermal speed control, allowing it to adjust its speed depending on the temperature of the environment.

In summary, 9GV1248J101 is a DC brushless fan offering low noise and high reliability. It is perfect for cooling applications and features a dual-ball bearing for long-term durability. It is suitable for computer, consumer electronics, industrial, and telecom applications where cooling is essential. The fan is driven by an internal DC motor and is controlled with a PWM signal, allowing it to adjust its speed depending on the temperature of the environment.
