What is the voltage range of the DC cooling fan?

When choosing a cooling fan, many people worry that the unstable power supply voltage will damage the cooling fan. Therefore, they often ask about the voltage range of the cooling fan they choose. Commonly used voltages for cooling fans are 5V, 12V, 24V, and 48V. The operating voltage range is generally +/-10% of the rated voltage. There is no problem with fluctuations. Operating within the operating voltage range does not mean that the speed at low voltage and high voltage is also the same. The cooling wind will vary with the voltage. As the speed increases, the current increases, and the motor temperature also increases. The cooling fan with a rated voltage of 5V, the operating voltage range is 4.5V-5.5V, and the cooling fan with a rated voltage of 12V, the operating voltage range is 10.8V-13.2V The rated voltage of the cooling fan is 24V, the working voltage range is 21.6V-26.4V The rated voltage of the cooling fan is 48V, the working voltage range is 43.2V-52.8V For some ultra-high speed cooling fans, the lower limit of the voltage can actually be lower For ultra-low speed cooling fans, the lower limit of voltage may be higher. Lower speed may fail to start work at low voltage. The copyright of the dynamic information of the micro DC fan belongs to the cooling fan manufacturer. Please do not reprint the whole article.
