Cooling fanWhat are the basic requirements of? Do you know that many purchasing companies' manufacturers are not familiar with the cooling fan industry and do not know where to start when choosing a cooling fan Shenzhen Yingtian Electromechanical Equipment Co., Ltd. will introduce some basic requirements for cooling fans:

    1. Automatic protectionAutomatic locking/starting function, the fan can automatically cut off the power in case of jamming or stalling, achieving the purpose of protecting electronic components and preventing equipment from burning out due to winding

  2. FG functionThe fan comes with an output square wave high and low level signal, and customers can determine the speed based on the frequency of the fan square wave to achieve the purpose of detecting the operation status of the fan

    3. RD functionWhen the fan is running normally, it remains at a continuous low level. If the fan gets stuck or experiences external blockage, it will immediately output a high level. Customers can detect this level to achieve the purpose of the fan alarm function

    4. TC functionThe fan changes speed according to changes in ambient temperature. If the ambient temperature is high and the air volume increases, the fan will decrease or stop to achieve the goal of reducing consumption.

 5. PWM functionThe fan adjusts its speed according to the external PWM duty cycle pulse width, which has the advantages of precise and simple speed regulation, low cost, etc

    6. Voltage regulationThere are two types: the first is power supply voltage speed regulation, which is easy to operate but has rough speed regulation; the second is voltage signal speed regulation, which controls the fan speed through a narrow voltage range

    7. Dustproof and moisture-proofDustproof, completely prevents dust from entering, does not affect the normal operation of electrical appliances, moisture-proofPrevent water from entering the fan from all directions and causing damage.
