1. It can support both fan speed control at the same time 2. Wide voltage design, supporting 12V/24V 2/3/4 wire fan/motor connections, with a maximum driving current of 4A 3. Automatically adjust the fan speed/air volume based on the detected temperature, fully automatic linear stepless speed regulation, energy-saving and noise reduction 4. The speed regulation mode supports two working modes (temperature adjustable mode/temperature fixed mode), and the mode can be switched by flipping the mechanical switch on the board 5. The temperature sensing line comes with mounting ears for easy fixation and can be used to measure the temperature of air, liquid, and solid surfaces The governor comes with two LED indicator lights to indicate power and working status Product Introduction: This temperature control governor adopts PWM pulse voltage regulation technology to achieve temperature control speed regulation. The governor monitors temperature in real-time and controls the fan speed based on the detected temperature. The higher the temperature, the faster the speed. The lower the temperature, the slower the speed. When the ambient temperature is lower than the set starting temperature, the governor controls the fan to stop running, thereby achieving the goal of reducing noise at low temperatures and quickly dissipating heat at high temperatures.
