E1225S05B-FSR

DC fans are commonly found in consumer electronics and industrial cooling applications. The E1225S05B-FSR is a type of DC fan, featuring a 4-wire design, making it simple to connect to the power supply. It is also one of the most common Fan System for PC cooling as it is efficient and cost-effective.

The E1225S05B-FSR uses a brushless DC motor to drive a fan blade designed to draw air away from the device\'s interior or exits it from the exterior, depending on the application. In most cases, the blades rotate in a clockwise direction, with the blade\'s long axis running from the hub to the outer edge. This setup ensures that the air is sucked in from the outside and pushed outwards from the interior.

The fan motor is powered by a DC voltage from a power supply, typically between 6 and 12V, although other voltages can also be used. In industrial systems, the DC fan may operate at higher voltages, such as 24V or 48V, depending on the application. The fan is then controlled by two control lines, providing the ability to change the fan\'s speed and/or direction.

In some applications, the fan can be powered by AC current. This type of configuration is often used in industrial fans, as it is resistant to voltage fluctuation and power outages. Typically, an AC voltage is used to power the fan, while a DC voltage is used to control it.

The E1225S05B-FSR is a compact and efficient fan, with a dynamic voltage range of between 4.5 to 13.2V DC. It has a nominal speed of 6500rpm and offers minimal audible noise at 17.9 dBA. The operating temperature range for the fan is 0 to 70° Celsius.

The fan\'s four-wire system includes the main power pins, a speed control pin, and a logic pin. The main power pins provide the power to the fan motor and can be connected to a power supply module. The speed control pin is connected to a PWM signal and provides the fan with a variable speed range, typically from 4500 to 6500rpm, while the logic pin is connected to the fan\'s electronics, allowing the fan to be monitored and controlled.

The E1225S05B-FSR is commonly used in applications such as cooling servers, graphics cards, or even air conditioners. In these applications, the fan helps to maintain an optimal operating temperature, by circulating the air in the device and removing heat from its components. Additionally, the fan\'s four-wire design allows it to be easily connected to the power supply, allowing for simplified setup and control.
