DC Fans

The MSI1225L24B2-BBR is a Brushless DC (BLDC) fan that is part of a class of fans known as DC fans. DC fans are typically used in applications that require the highest level of air circulation and cooling in minimal amounts of space.

DC fans are designed to use the same principles as AC fans, however, they differ in that they are powered solely by direct current (DC) as opposed to the alternating current (AC) used by AC fans. This allows DC fans to run much more efficiently and with greater reliability as their power source is much more consistent and predictable. Additionally, due to their DC nature, these fans are designed to spin at higher speeds and with greater power than their AC counterparts.

The MSI1225L24B2-BBR is widely used across industrial and commercial applications. This is due to its high efficiency, reliable performance, and relatively compact design. The fan operates via four phase motors, and features high durability, with an expected life-span of up to 50,000 hours. It is also optimized for low noise operation, producing noise levels of only up to 32dBa at full load.

The fan’s power requirements are 12 VDC and has a current draw of 0.3A at full load. This makes it particularly suitable for high-end embedded applications where system compatibility is key. Furthermore, the fan is available in two sizes, d25mm, and d40mm, with the latter having slightly lower power requirements (0.2A).

The working principle of the MSI1225L24B2-BBR is relatively simple. It operates by a four-phase motor which features four out of phase magnetic fields, with the rotation of the motor being driven by an external motor driver, typically a PWM signal, with the fan speed being adjustable. This is further enhanced by its low start voltage of 3.0V and its PWN ramping capability.

In summary, the MSI1225L24B2-BBR is a highly efficient Brushless DC fan, featuring a four-phase motor and high durability components. It is suitable for a wide range of applications, both commercial and industrial, due to its wide range of features, and its highly efficient and reliable design.
