DC Fans

DC (direct current) fans employ the use of electronic components and operate off of a direct current rather than an alternating current as traditional electric fans do. DC fans generally use built-in speed control mechanisms to regulate their operation parameters such as speed and airflow, and are often quieter and have higher efficiencies than their AC counterparts. DC fans are also increasingly more popular because of their higher reliability due to their lack of thermal components.

109P0424F602 Application Field and Working Principle

The model 109P0424F602 DC fan is a 24 Volt, 4-wire DC axial fan with a nominal diameter of 109mm. It utilizes a brushless DC motor and is thermally protected with a built-in thermistor to prevent damage to the motor in the event of motor over-temperature. The fan is designed for a wide range of applications such as cooling components in computers, appliances, audio and visual equipment, industrial equipment, and many other consumer electronics.

The 109P0424F602 fan operates on 24V DC, drawing around 0.3A at maximum speed, and pulls around 45CFM of air at a static pressure of 0.11 in H2O. The fan is designed to run at speeds up to 6,300RPM and offers variable speed control via an external potentiometer pin. Different tachometer outputs are available depending on the version.

The fan motor uses a unique design that combines axial and radial blade geometry to ensure high performance. This design helps to minimize cross-flow turbulence and reduce noise levels. The motor also utilizes rare earth magnets that provide maximum dynamic torque and heat resistance, as well as excellent structural integrity. The entire motor assembly is designed to remain thermally stable even in adverse conditions.

The 109P0424F602 fan is built using a high-performance double ball bearing system, which helps to ensure reliable operation in a wide range of environments. The system is designed to remain cool during operation and last for up to 70,000 hours of continuous use. The fan utilizes a tachometer output that indicates the current speed of the fan in RPM, and the fan is thermally protected with an internal thermistor that cuts off the power supply in the event of over-temperature.
