What are the voltage specifications of the DC cooling fan

A DC cooling fan is a cooling fan that uses DC power supply. The specifications of the DC voltage vary according to the characteristics of the product and the use environment. What are the specific ones? The commonly used DC voltage is 12V, so almost all specifications of fans are There are 12V design and production, and all walks of life use 12V DC fans the most, followed by 5V and 24V. 5V is mainly used in vehicles, smart wearables, and battery products. 24V is mainly power products. Unconventional voltages are 3.3V, 48V, and even more unconventional cooling fans such as 6V, 9V, 16V, 28V, 64V, etc. The manufacturer has a professional Ru0026D team, and can design the circuit by itself, and customize a variety of different voltages and non-functional cooling fans for customers.
