Electric Fan Speed Controller Used For Management Of Rotational Speed

Product Description

The Fan Speed Controller used for management of the rotational speed of electric fans from 60, 80 and 100 V AC to 12, 24 and 48 V DC is designed for processes control, industrial control and automation. The device enables precise regulation of the speed of low-voltage fans which do not have an integrated speed controller.This controller is used for management of the rotational speed of electric fans. It can directly use for DC fan motors to adjust the fan speed in a wide range, and it has light weight, easy to carry and simple structure. The working principle is that the frequency of pulse signal into the speed control adaptive filter, which amplifies and filters the pulse signal to make the motor speed.
