UPS power supply power is high, the temperature rises, need to increase the cooling fan to reduce the system temperature, between the characteristics of the product, generally have the following requirements for the cooling fan:
1.Long service life, for which Yirongchuan Technology has specially designed hydraulic bearings, with a life of up to 350,000 hours.
2.Low noise, because the UPS power supply is close to people, so the noise requirements for micro fans are high.
In view of the instability of the voltage of the UPS power supply to the cooling fan, Yi Rongchuan will also increase the voltage range at the beginning of the design.
For special occasions, customers require that the speed of the cooling fan is intelligently regulated, generally when it is overheated, it is hoped that the speed will be faster, and when the temperature is slightly lower, it is hoped that the speed can be reduced
1.PWM speed regulation function: it automatically adjusts the speed according to the frequency of use of the system, the higher the duty cycle, the faster the speed, the lower the duty cycle, the lower the speed. For example, the higher the frequency of our computer's CPU, the higher the temperature at this time, and the faster the cooling fan will rotate.
2.Temperature-controlled: The higher the ambient temperature, the faster the cooling fan will rotate, and vice versa.
This kind of cooling fan with intelligent speed regulation function can not only extend the service life of the cooling fan, but also not make the cooling fan crazy and produce loud noise at low temperatures.
