DC Fans
DC fans are the most widely used type of fan in the world today. DC fans can be used both in air conditioning and industrial applications. DC fans are typically much more efficient than AC fans, and they can provide a more consistent and reliable performance. The PFB1248XHE-TP17 is one of the most popular DC fans on the market.
Application Field
The PFB1248XHE-TP17 is an Ultra Thin DC fan and is an ideal cooling solution for low profile applications. This fan is perfect for thin wall or ultra-compact applications such as consumer electronics, manufacturing and testing equipment, and industrial automation. This fan features a low noise level of 17dB-A and a maximum airflow of 35 CFM. This fan is rated for a maximum static pressure of 0.7 inH2O and can operate up to 6,000 RPM.
Working Principle
The PFB1248XHE-TP17 is a DC brushless fan and has four built-in Leuze Andon sensor within the fan. This sensor measures the fan speed and also enables the fan to respond to changes in the operation of the device it is cooling. The fan operates at a nominal voltage of 12VDC and can be adjusted to match the voltage of the device it is cooling. The fan is driven by a low-profile 4-pole electric motor that is powered by a 3-phase PWM signal.
The fan\'s motor speed is controlled by the 4-pole electric motor which is connected to a control board that receives the PWM signal from the power supply. The PWM signal is then forwarded to the Hall Effect sensor, which monitors the movement of the fan blades and adjusts the speed of the fan according to the signal received. The fan\'s speed is also monitored to ensure that it is not spinning too fast or too slow. The three-phase PWM signal ensures that the motor runs at its optimal performance.
Conclusion
The PFB1248XHE-TP17 is an Ultra Thin DC fan that is perfect for cooling low profile applications. This fan is highly efficient and reliable, and has a maximum airflow of 35 CFM and a maximum static pressure of 0.7 inH2O. This fan is driven by a low-profile 4-pole electric motor that is powered by a 3-phase PWM signal and has four built-in Leuze Andon sensor that measures and adjusts the motor speed to ensure optimal performance.
