Application Field of BFB04512MD-F00
The BFB04512MD-F00 from Delta Electronics is a DC fan that belongs to the BFB series. It is designed to meet the cooling needs of a wide range of devices across the industrial, commercial and consumer electronic equipment markets. The fan has a width of 45mm and a height of 12mm and is designed for use in tight spaces. Its aerodynamic plastic impeller allows for a wide operating range and its quiet operation is well suited for a range of applications, from small systems to large ones.The BFB04512MD-F00 is a low-noise solution that offers a maximum speed of 7200RPM and airflow up to 26CFM. It has excellent motor efficiency and power savings, operating at 12V DC. This fan is designed for long life and is protected against dust and moisture with its IP44-rated enclosure. With a maximum power rating of 1.8W, the BFB04512MD-F00 is both rugged and reliable and is RoHS and CE compliant.Working Principle of BFB04512MD-F00
The BFB04512MD-F00 works on the principle of PWM (Pulse Width Modulation) signal control. It operates using a three-phase motor that has a rotating magnetic field to spin the fan blades. When the fan’s speed needs to be increased, a PWM signal controls the voltage across the terminals, increasing its speed. Likewise, when the fan’s speed needs to be reduced, the voltage decreases and the fan motor slows down.Additionally, the fan has an overcurrent protection feature that cuts the power supply if the current exceeds the specified limit. This ensures that the fan does not overheat or fail due to excessive current. The PWM control also allows for silent operation as it eliminates the need for a noisy start control circuit. This feature allows for quiet operation even at low speed.Conclusion
The BFB04512MD-F00 from Delta Electronics is a DC fan that is designed for usage in a range of applications across various markets. It operates on the principle of PWM signal control and is designed for low noise and long life. This fan is rated at 12V DC and offers a maximum speed of 7200RPM and airflow of up to 26CFM. It is both rugged and reliable, and with its overcurrent protection feature, is well suited for a range of applications from small systems to larger ones.The specific data is subject to PDF, and the above content is for reference
