9WP0924S402

DC fans are a type of fan units using direct current power for their motor rotational power. An example of a DC fan model is 9WP0924S402, which is typically used in desktop computer systems to cool down the device\'s internal components. This type of fan has become increasingly popular in recent years due to its ability to provide reliable and energy-efficient cooling, as well as its low price point and wide availability in electronic markets.

The 9WP0924S402 DC fan is a high-performance unit that uses a four-wire connection. This means that the fan has four distinct pins for power and speed monitoring. The pinout for the unit is Vcc, PWM, Ground and Speed. Vcc supplies the motor with power, while PWM allows the user to manage the speed of the fan using a compatible controller. Ground obviously is used to provide a proper ground connection, and Speed provides feedback on the fan\'s current rotational speed.

The 9WP0924S402 DC fan is a versatile unit, capable of operating between 0-17 volts, and between 0-3000 RPM. The fan\'s design allows for efficient cooling, as well as low acoustic noise levels. It can be used in a variety of applications, including computers and gaming consoles, consumer electronics, and industrial equipment. It is also compatible with most conventional fan controllers and thermal sensors.

In terms of performance, the 9WP0924S402 DC fan is able to provide up to 70 CFM (Cubic Feet per Minute) of airflow, with a minimum noise level of 10 dB. This makes the fan well-suited for a wide range of applications, including those where quieter operation is desired. In addition, the fan has an operating lifetime of up to 168,000 hours, making it a durable and reliable option.

As for the 9WP0924S402 DC fan\'s working principle, the unit utilizes a brushless DC motor. This motor contains permanent magnets and a rotor and stator. The magnets are arranged in a specific way to generate a rotational force, which then drives the fan blades to spin. The speed of the motor is adjusted using a compatible controller, such as a pulse-width modulation (PWM) controller. This allows users to set the fan to a specific speed, resulting in more efficient cooling performance.

Overall, the 9WP0924S402 DC fan is a reliable and efficient unit that is suitable for a wide range of applications. Thanks to its low price point and wide availability, as well as its low noise levels and high performance, the fan is a popular choice for many desktop computer systems and other types of electronic equipment.
