The KD1204PFB1 DC fan is a popular choice for numerous applications due to its high-quality and dependable performance. It is a four-wire, 90 x 25mm double ball bearing fan that features oil-less bearings and long life. The motor is engineered to run at 12V and it operates at a maximum of 0.13A, with a maximum speed of 3000RPM. The fan is intended for direct connection to the DC bus and it has a PWM control. The KD1204PFB1 DC fan also has good acoustic performance due to its advanced acoustic design.

The KD1204PFB1’s application field can vary depending on the needs of the user. It is popularly used as a cooling system for power semiconductors, power converters, industrial electronics, and high-power LED lighting applications. It also offers excellent heat dissipation in three-phase power supplies and ARM processor cooling.

The working principle of the KD1204PFB1 DC fan is based on a brushless axial fan motor. The fan’s external rotor design provides for a more efficient cooling of the motor and increases the airflow. The control of the motor is achieved through a pulse width modulated (PWM) control. This is a method of controlling motor speed by varying the motor’s pulse width or the percentage of the total on time of the motor’s cycle. The fan is equipped with a tachometer that senses the fan’s speed and adjusts the output of the motor depending on the load. This ensures that the fan can reach its maximum performance.

The DC fan also has additional features that make it an ideal choice for numerous applications. It has been designed with an optimized propeller size that allows for a higher airflow and a lower noise level. The fan also features a power protection system that allows for continued protection of the fan motor even when it is operating at higher temperatures. Additionally, the DC fan has a low-voltage shutdown mechanism that helps protect the motor in case of overload or when motor current is too high.
