DC fans are one of the most common components used in electronics today. They are designed to draw air or other gases into the system, creating a cooling effect. OD1225-24MB is one of the most popular models of DC fan, and the purpose of this article is to provide an overview of its application field and working principle.

The OD1225-24MB is primarily used in computers, and is the most commonly available fan size for personal computers. It is designed for use in systems with ATX or SSI form factors, providing a reliable cooling mechanism. Additionally, due to its small size and low power consumption, this fan can also be used in smaller electronics such as portable media players, game consoles, and handheld devices.

The OD1225-24MB is a brushless DC fan, meaning that it operates using an electronically commutated motor (ECM). This type of motor is different from the traditional AC motor because it does not rely on a mechanical commutator to switch the current direction in the wires. Instead, the ECM uses three-phase power to rotate the rotor, and an electronic controller to adjust the speed and direction of rotation. This makes it more efficient than an AC motor, which requires a larger power supply and generates more noise.

The OD1225-24MB also features a three-pin connector, which is used to connect the fan to a power source, as well as to provide a tacho signal back to the system. The tacho signal indicates the speed of rotation and is used by the system to monitor and adjust the speed of the fan.

Another feature of the OD1225-24MB is its specially designed blades. The fan blades are designed to minimize the acoustic noise generated by the fan when operating. This is important for computers, as it prevents the generation of distracting and annoying noise.

Finally, the OD1225-24MB also features protections against overvoltage, overheating, and reverse polarity. These features ensure that the fan will continue to operate correctly, even if the power supply is irregular or if mistakes are made during installation.

The OD1225-24MB fan is a great choice for PCs and other small electronic devices. It is highly reliable, energy efficient, and is designed to minimize noise. Moreover, it includes protections against overvoltage, overheating, and reverse polarity, making it perfect for applications with strict safety requirements.
