1. Using high-quality materials, the quality is guaranteed
2. The appearance of the product is exquisite and small
3. Supports low temperature shutdown of fans within 3A, can directly turn off the fan power, and supports back-sequence fans
4. The product wiring is simple and convenient
5. Support four-wire fan speed regulation
Design power supply voltage: DC12V
Voltage range: DC8-16V (circuit operating voltage, please pay attention to the fan voltage range)
Circuit self-consumption: less than 40mA (tested at 12V)
Fan current: no more than 3.3A
PWM range: 1-100 (signal percentage is not actual speed ±0.5%)
PWM frequency: 25KHZ (plus or minus 1KHZ)
PWM signal amplitude: 5V (no load)
Temperature measurement range: -9.9-99.9℃
Temperature measurement error: the error in the range of 0-50°C is lower than 1.2°C, and the error in other ranges is lower than 2°C
1. This control only controls the speed adjustment of the fan controlled by the four-wire standard PWM signal. The signal specification is 25KHZ 5V. Conventional chassis, CPU and many server four-wire fans support it, but it cannot control the speed regulation of 2-3 wire fans!
2. The difference between the acceleration temperature and the full speed temperature should not be lower than 5°C, and the difference between the shutdown temperature and the acceleration temperature should not be lower than 2°C. When modifying the parameters, if the value breaks the above temperature difference, the program will automatically adjust the other two parameters.
Three-digit digital tube: display specific parameters and values
LED "×10 RPM": Speed unit light This light is on and the digital tube displays the fan speed. The value is the value after dividing the speed by 10. For example, if 256 is displayed, the actual fan speed is 2560RPM (revolution/min)
LED "℃": temperature unit light, this light is on and the digital tube displays the temperature measured by the current probe
LED "RUN": Fan running indicator light on when the fan is running and off when the fan is off
