The air volume, air pressure and noise of the cooling fan are the problems that users like to talk about. The noise of larger wind volume will naturally increase, with the change of the four seasons, the temperature will also be different. The air volume is higher in summer and lower in winter. How do we balance this problem and solve it? Major Fan Manufacturers have developed adjustable speed fans. This product can be based on the actual must adjust the fan speed, can greatly reduce the fan noise and power. What is the speed regulation method commonly used for fans? 1. The rotating speed of the industrial cooling fan can be adjusted by adjusting the working power supply voltage. 2. The pulse width modulation (pwm) speed regulating cooling fan is regulated by a special pwm speed regulating control circuit. The control signal will be completed by the cooling fan manufacturer. The function uses frequency and high and low pressure levels to control fan speed. The Fan speed is controlled linearly by adjusting the duty cycle. A Fan with pulse width modulation is usually used in conjunction with four conductors. 3. Temperature control function TC: When this function is applied, the speed of the fan is controlled by the temperature. Different problems can correspond to different speed. This function should be performed by the manufacturer of the Cooling Fan. 4. The circuit of the Industrial Cooling Fan can increase the resistance, reduce the voltage of the power supply, and achieve the goal of speed regulation.
