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

1. High quality materials with guaranteed quality2. Product appearance is exquisite and 3. Support the low temperature shutdown of fans within 3A, can directly turn off the fan power, and support the back sequential fan4. The product wiring is simple and convenient5. Support four wire fan speed regulationDesign power supply voltage: DC12VVoltage range: DC8-16V ( 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 3.3APWM range: 1-100 (signal percentage non actual speed 0.5%)PWM frequency: 25KHZ (plus or 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, 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 the above temperature difference when modifying the parameter, the will automatically adjust the other two parameters.Colour:blackMaterial:plastic+metalPackage Contents:1 x PWM Fan Temperature Control1 x probeOnly the above package content, other products are not included.Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
