DC fans are widely used in many different markets including automotive, computer, consumer products and telecommunication. FFB03812VHN-9C3P stands out among them because of its unique characteristics.

Application Field

FFB03812VHN-9C3P has a wide range of applications because of its small size and powerful output. It can be used in either ambient or enclosed environments. It is widely used in Automotive, computer & consumer products, telecommunication, industrial and medical fan markets.

Working Principle

FFB03812VHN-9C3P is a DC fan with a circular fan blade design to maximize air movement. It features a double bearing design for longer life and a low-noise operation. The fan motor is based on a permanent magnet dc motor and the power supplied to the fan motor is controlled by a variable PWM signal, which can be generated by a micro-controller. The fan motor is designed to rotate at a constant speed, and the motor is electronically commutated for optimal efficiency.

The fan motor has a two-wire connection, which includes an input voltage and ground. This allows the fan motor to be connected directly to a battery, or to a DC voltage source such as a single-supply regulator. The fan is controlled via a PWM (Pulse Width Modulation) input signal which is used to adjust the fan speed. The PWM signal can be generated from a microcontroller, or from a temperature sensor.

The fan also contains a built-in thermal overload protection circuit to protect the motor from excessive heat and current. This protection circuit will shut down the fan if the current level in the motor increases beyond its safety limits.

Conclusion

In conclusion, FFB03812VHN-9C3P is a versatile DC fan suited for various applications. It features a permanent magnet motor, double bearing design, and low-noise operation. It is a powerful and reliable fan that can be controlled via a PWM signal, and provides thermal overload protection for increased safety.
