DC 12V Mini 4 Wire PWM Fan Temperature Control Governor Temperature Speed Digital Display Support 3A Fan On/Off Control
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
Product parameters:
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 ¡É
Temperature measurement error: within the range of 0-50 ¡É, the error is lower than 1.2 ¡É, and the error in other ranges is lower than 2 ¡É
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 ¡É, and the difference between the closing temperature and the acceleration temperature shall not be less than 2 ¡É. If the value will break the above temperature difference when modifying the parameter, the program will automatically adjust the other two parameters.
Display description:
Three digit digital tube: display specific parameters and values
LED¡° × 10 RPM ": the speed unit light is turned on. The nixie tube displays the fan speed. The value is the speed divided by 10. For example, if 256 is displayed, the actual fan speed is 2560RPM (r/min)
LED "¡É": temperature unit light This light turns on the nixie tube and displays the temperature measured by the current probe
LED "RUN": the fan running indicator lights up when the fan is running and turns off when the fan is off
Package included:
1pcs x DC 12V Mini 4 Wire PWM Fan Temperature Control Governor Temperature Speed Digital Display Support 3A Fan On/Off Control
