(Summary description)Requirements for voltage, amplitude and frequency of SanAce Computer fan pwm speed regulation drive In practical applications, efficient heat dissipation systems are crucial for the reliability and performance of equipment. As one of the core components of the cooling system, the Computer fan undertakes the important task of removing a large amount of heat generated by the equipment. Its stability and reliability are critical to the normal operation of the entire system. In order to realize the precise control of Computer fan, PWM (Pulse Width Modulation) technology is widely used in the speed control drive circuit. However, the PWM speed regulating driving voltage, amplitude and frequency of the Computer fan need to meet certain requirements to ensure its normal operation and stability. These requirements may vary depending on different fan models, manufacturers, and applications. Here are some common requirements: 1. Drive voltage The driving voltage of Computer fan is one of the key factors to ensure its normal operation. Generally, the driving voltage of Computer fan is DC voltage, and the common range is 12V; But other voltages, such as 5V or 24V, can also be used, depending on the specifications and design requirements of the fan. When using PWM speed control drive, the stability and accuracy of the voltage are very important to ensure that the fan can operate normally and adjust the speed as needed. If the voltage is too low, the fan may not start normally or the speed may be too slow; If the voltage is too high, it may cause damage to the fan circuit and motor. Therefore, before selecting the PWM speed control drive voltage, it is necessary to carefully study the fan specification sheet or manufacturer's manual to ensure that the selected drive voltage range is suitable for the target fan. 2. Amplitude The amplitude of PWM speed regulation refers to the voltage difference between high and low levels. Generally speaking, the common PWM amplitude is 3.3 volts (V) or 5 volts (V), but the specific requirements depend on the specifications and design of the fan. When selecting a wide value, it is necessary to ensure that the PWM signal can be correctly understood and responded to by the fan. You can refer to the specifications of the fan or the technical information provided by the manufacturer to understand the PWM bandwidth requirements for using the fan. 3. Frequency The frequency of PWM speed control drive voltage refers to the periodic repetition frequency of pulse signals. The frequency selection should be determined based on the characteristics and application requirements of the fan. The common PWM frequency range is from tens of Hertz to hundreds of Hertz. A lower frequency may cause a delay in the response time of the fan speed, while a higher PWM frequency can provide smoother and more accurate speed adjustment, but it also increases the electromagnetic interference of the system. Therefore, when selecting PWM frequency, it is necessary to comprehensively consider the accuracy of speed regulation and the Electromagnetic compatibility of the system. The PWM speed regulating driving voltage, amplitude and frequency of the Computer fan need to be selected and adjusted according to the specifications and design requirements of the fan to ensure that the fan can work normally and stably, and can provide the required speed adjustment range and accuracy.
