DC Fans are essential components used widely in many electrically driven equipment. The G1238H48B-FSR is a common type of DC Fan which offers high reliability and excellent performance. It is known for its low power consumption, low noise, and small size. This article will explain the application field and working principle of this DC Fan.

Overview of G1238H48B-FSR

The G1238H48B-FSR is a type of DC Fan that comes with an overall fan size of 38 mm, a height of 12 mm, a frame size of 48 mm, and a depth of 13.7 mm. It provides a maximum fan speed of 13,500 RPM and a maximum airflow of 6.7 CFM, with power input of 0.12W. In terms of noise level, the G1238H48B-FSR fan operates at a sound pressure level of 27 dBA.

Applications of G1238H48B-FSR

The G1238H48B-FSR DC Fan can be used in various types of applications. Its small size and low power consumption makes it ideal for applications that require low noise or small spaces. It can be used in electronic devices such as laptops, desktop computers, monitors, TVs, and other electronics that require a cooling fan. Other possible applications include small motor-driven devices, telecommunications and control systems, and point-of-sale systems.

The G1238H48B-FSR is designed for both indoor and outdoor applications. It is dust-proof and water-proof, making it suitable for hostile environments such as factories and warehouses. With its long MTBF (Mean Time Between Failures) rating of 50,000 hours, it is also suitable for applications that require reliable and constant cooling.

Working Principle of G1238H48B-FSR

The G1238H48B-FSR DC Fan operates on the principle of air pressure. It works by creating a pressure difference between two sides of the fan blades by drawing air into the fan from its intake side and discharging air from its exhaust side. This pressure difference results in a spinning motion of the fan blades, causing air to flow through the fan in an organized and efficient manner.

The fan speed of the G1238H48B-FSR is regulated by changing the voltage that is applied to the fan. When the voltage is increased, the fan speed increases. When the voltage is decreased, the fan speed decreases. The fan is equipped with a speed control sensor which automatically adjusts the voltage in order to maintain the desired fan speed.

The airflow produced by the G1238H48B-FSR is determined by the size and design of the fan along with the speed of the fan blades. The fan is designed to provide maximum airflow while maintaining a low noise level.

Advantages of G1238H48B-FSR

The G1238H48B-FSR offers several advantages compared to other DC Fans. The fan has a small size and low power consumption, which makes it an ideal choice for cooling devices like laptops and desktop computers. It also has a longer MTBF rating than conventional DC Fans. The fan is designed for both indoor and outdoor applications, and it is dustproof and waterproof, so it can be used in hostile environments. Finally, the fan is equipped with a speed control sensor which allows it to maintain its desired speed, even when the voltage is changed.

Conclusion

The G1238H48B-FSR is a type of DC Fan offering excellent performance and reliability. It is ideal for applications that require low noise and small spaces such as laptops and desktop computers. It is also designed to be dustproof and water-proof, making it suitable for use in hostile environments. Finally, the fan is equipped with a speed control sensor which allows it to maintain its desired speed, even when the voltage is changed. This makes the G1238H48B-FSR an ideal DC Fan for many applications.
