DC Fan is used in a wide range, many customers require DC fan speed adjustment function, fan speed adjustment can not only make DC fan more stable and reduce noise, let's look at DC fan speed adjustment function? 

DC Fan can adjust the speed, the speed is fixed frequency pulse, adjust its width to change the speed of the fan, but also according to the needs of customers to formulate, in general, the DC fan of the power supply achieves speed regulation by adjusting the working power supply voltage, the fan of the PWM speed regulation function can not be adjusted by the working power supply voltage, there is a PWM speed regulation control circuit to regulate, the duty cycle of PWM signal is adjusted by measuring the temperature, so as to control the speed of Fan.

 The above is a simple introduction of DC fans can be adjusted speed, I hope to help you, Dongxing Yue professional production of cooling fans for 12 years, in the industry has a good reputation, in order to adapt to the changes in the market environment, in order to constantly improve product quality, the pursuit of production results, make our products more refined, improve market competitiveness, we are direct production and processing of various products, and we buy directly can be preferential, if you need to compare our fans, a good cooling fan can not only maintain the normal operation of the equipment, but also improve the efficiency, want to know more about the cooling fan can pay attention to us.
