8312/10MV

DC fans refer to fans with DC brushless motors or DC brush motors as the driving force. DC fans are widely used in various electronic devices and systems. The 8312/10MV belongs to this category of fans. It is a high-efficiency fan specially designed for high-power system products.

The 8312/10MV DC fan utilizes a two-stage sensitivity control circuit to make full use of the fan’s rotation speed characteristics in order to reach the optimal working speed. The specific application field and working principle of this fan can be described as follows.

Application Field

The 8312/10MV fan is mainly used in servers, communication equipment, medical imaging equipment, industry control equipment, consumer electronics and other high-power system products. It has high static pressure and air volume, low noise, and good stable performance. The fan offers long-time continuous work under high temperature condition; it can bring the best cooling effect to the system.

Working Principle

The working principle of the 8312/10MV fan is somewhat similar to the working principle of the DC brushless motor fan. It utilizes the two-stage sensitivity control circuit to obtain the optimal working speed. This circuit consists of a Hall elements, a bridge circuit with two resistors and a capacitor, along with a MOSFET switch.

To start the fan, the current will first increase in order to reduce the voltage between two edges of the Hall element. When the voltage reaches the threshold voltage, the switch will start to close, so that the two resistors will be connected and energized. When this phase is complete, the switch will open and two capacitors will be connected to the terminals. This way, the circuit will feedback and stabilize the operating speed of the fan.

This circuit will enable the fan to reach its full operating speed while consuming less electricity, thus providing excellent cooling effects with minimum noise. It can also reduce the vibration and fluctuation of the fan and increase the lifespan of the product.

In summary, the 8312/10MV is an excellent DC fan for high-power system product and can provide optimum benefits to these products. With its efficient and stable performance, it is a reliable solution for cooling system needs.
