1. The governor controls the speed of the fan based on the detected temperature. The higher the temperature, the faster the speed. When the temperature is lower than 30 degrees, the governor controls the fan to stop running. When the speed is higher than 30 degrees, the fan starts at a low speed. If the temperature continues to rise, the fan speed will slowly increase. When the temperature rises to 50 degrees, the fan will run at full speed. When the temperature begins to fall and falls below 50 degrees, the fan speed will slowly decrease to 30 degrees. At the time, the fan is turned off and the cycle works.

 

2. If the fan fails or other factors cause the temperature to exceed 55 degrees, the governor will output an OC signal to indicate the current temperature alarm!

1. Supports a variety of 12V/24V/48V 2, 3, 4 wire DC fan access, maximum drive current 12A
