Many customers in the choice of cooling fan according to their product needs to choose parameters, some customers choose voltage, there will be a choice of DC and AC, the following we know about cooling fan 220V IS DC or AC. Cooling Fan we common DC 12V 24V 48V, AC 110V 220V 380V, cooling fan 220V for the commonly used standard voltage, cooling fan 220V AC and DC difference is the output mode is not the same, DC fan voltage is generally relatively small, dC and mode of production are not the same, they vary in size and direction, they vary in transformation. The above is the cooling fan 220V introduced by Dong Xing Yue is DC or AC, a good cooling fan is very important, not only to make the normal operation of the equipment, but also to extend its service life, work efficiency is also increased, if you want to know more about the cooling fan knowledge can follow us.
