Often customers ask whether the DC fan speed can be adjusted? Is there anything on the fan that can be adjusted at will? The speed control function is one of the main differences between the DC fan and the AC fan, but it depends on how to adjust and how to adjust it. It is mainly related to the matching of the client. The DC fan itself is a fixed motor and will not change. When the external conditions change, the speed of the DC fan can change accordingly.
For example, PWM adjusts the speed according to the high and low frequency, the most commonly used is the computer CPU fan. If you change the input voltage of a DC fan, the most common one is a handheld DC fan
DC fans can be customized with different high and low speeds according to customer requirements. Some people say that AC fans can also be used, but AC fans only adjust the speed within a small float, while DC DC fans can adjust the float very large, with a small speed of 10 %, up to 100%. The cost of high and low speeds may also vary several times.
