DC fans are powered by direct current, which means that a single external voltage is used to run the fan motor. DC fans tend to be quieter and more efficient than AC fans. The MR9238L24B2-FSR is a type of DC fan that is widely used in industrial applications. In this article, we’ll take a look at the application field and working principle of the MR9238L24B2-FSR.

Application Field

The MR9238L24B2-FSR is a reliable and efficient DC fan for applications requiring high airflow and pressure. It is suitable for long operational life in any environment. It can is particularly useful in automotive, industrial, and computer cooling applications. The fan runs at a low noise level, making it suitable for noise-sensitive environments. It features a unique design that helps to reduce vibration and noise during operation.

The fan is designed to operate in two modes: auto and manual. In auto mode, the fan will automatically adjust its speed to the environmental temperature and the cooling requirements. In manual mode, the fan speed can be manually adjusted according to the requirements of the application. The MR9238L24B2-FSR is equipped with overload protection and reverse polarity protection, which helps to prevent damage to the fan in case of incorrect wiring.

The fan is designed for use with 24 VDC voltage and produces a maximum airflow of 80.71 CFM and a max static pressure of 20.30 mm-H2O. It can operate in temperatures ranging from –40°C to 80°C. The fan also comes with an optional PWM control feature that allows for precise adjustments in fan speed for optimal performance at different temperatures.

Working Principle

The MR9238L24B2-FSR DC fan operates on the principle of electromagnetic induction. A voltage is applied to its two poles, and it generates a magnetic field. When the fan blades pass through this magnetic field, they experience a force known as the Lorentz force, which causes them to rotate. As the fan rotates, air is sucked in through the inlet and pushed out through the outlet. This process helps to cool the surrounding area.

The fan motor also contains an internal electronic circuit that helps to regulate the fan speed. When the fan speed needs to be increased, more voltage is supplied to the motor and it rotates faster. Conversely, when the fan speed needs to be decreased, the voltage is reduced and the motor slows down.

The MR9238L24B2-FSR DC fan also comes with an optional feature known as the tacho-alarm. This feature monitors the fan speed and raises an alarm when the fan speed drops below a certain threshold. This feature helps to ensure that the fan is operating at its optimal speed at all times.

Conclusion

The MR9238L24B2-FSR DC fan is a reliable and efficient fan for applications requiring high airflow and pressure. It is suitable for long operational life in any environment, and offers noise-reduction and vibration-damping features. It features an auto and manual mode and can be equipped with optional PWM control and tacho-alarm features. The operation of the fan is based on the principle of electromagnetic induction.
