YR-1001 temperature fan controller is an intelligent fan controller that can accurately control the speed of the fan. Automatically detect the machine temperature and control the fan speed in real time, achieving effective cooling effect while ensuring the safe and stable operation of the equipment.
The controller also has a temperature sensor fault diagnosis function. When a sensor problem is detected, the screen will display CER to remind the user, preventing equipment damage or accidents caused by overheating.

Product parameters
