2X DC 12V Mini 4 Wire PWM Fan Temperature Control Governor Temperature Speed Digital Display Support 3A Fan

2X DC 12V Mini 4 Wire PWM Fan Temperature Control Governor Temperature Speed Digital Display Support 3A Fan Description

1. High quality materials with guaranteed quality
2. Product appearance is exquisite and compact
3. Support the low temperature shutdown of fans within 3A, can directly turn off the fan power, and support the back sequential fan
4. The product wiring is simple and convenient
5. Support four wire fan speed regulation

Design power supply voltage: DC12V
Voltage range: DC8-16V (please pay attention to the fan voltage range for the working voltage of the circuit)
Circuit self consumption: less than 40mA (test under 12V)
Fan current: no more than 3.3A
PWM range: 1-100 (signal percentage non 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: within the range of 0-50 , the error is lower than 1.2 , and the error in other ranges is lower than 2
Matters needing attention:
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, which is supported by conventional chassis, CPU and many server four wire fans, but cannot control the speed adjustment of the 2-3 wire fan!
2. The difference between the acceleration temperature and the full speed temperature shall not be less than 5 , and the difference between the closing temperature and the acceleration temperature shall not be less than 2 . If the value will break the above temperature difference when modifying the parameter, the program will automatically adjust the other two parameters.
