Answer: Many people will think that the starting voltage of the cooling fan is the voltage on the label. In fact, the minimum starting voltage is much smaller than the rated voltage. Guangzhou Yijia Electronics will give you a brief introduction of these two kinds of voltages.

Working voltage refers to the stable and normal operation voltage of the cooling fan, i.e. rated voltage.

Start-up voltage refers to the minimum voltage that can make the fan start when the cooling fan is suddenly energized.

Start-up voltage, the normal rated voltage of DC fan is 12V, then start-up voltage is generally less than 7V, because the system supply voltage may be unstable, if the starting voltage is lower, the distance between the rated voltage and 12V will be larger, representing the wider range of operating voltage of the DC cooling fan, which can ensure low-voltage activation of the start-up fan when the voltage is unstable. Start-up voltage can be measured by multimeter and other detection tools. The low working current of the cooling fan not only reduces the power consumption, but also reduces the heat output of the fan, which can increase the service life of the fan. For oil fans, it can also slow down the volatilization of lubricating oil, so the lower the current, the higher the reliability of the fan.
