DC 12V 4 Wire PWM Fan Temperature Governor Speed Digital Display Support 3A On/Off Control

Description:

1.The product is made of high-quality materials with guaranteed quality

2.The product is designed with ultra small size, lightweight and compact, with digital display

3.Support four-wire fan speed regulation, product shipped with probe cable

4.Support low-temperature shutdown of fans up to 3A, able to directly turn off the fan power, and support reverse timing fans

5.Stable product performance and long service life

Parameters:

Design power supply voltage: DC12V

Voltage range: DC8-16V (circuit working voltage, please pay attention to the fan voltage range)

Circuit self consumption: less than 40mA (tested at 12V)

Fan current: not exceeding 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: The error within the range of 0-50 ℃ is less than 1.2 ℃ , and the error in other ranges is less than 2 ℃

Precautions:

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 should not be less than 5 ℃ , and the difference between the shutdown temperature and the acceleration temperature should not be less than 2 ℃ . If the value will break the above temperature difference value when modifying parameters, the program will automatically adjust the other two parameters.

Display description: three digit Nixie tube: display specific parameters and values

LED“ × 10 RPM “: the speed unit light is lit up and displayed on the Nixie tube as 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 2560 RPM (r/min)

LED ” ℃ “: temperature unit light This light turns on the Nixie tube and displays the temperature measured by the current probe

LED “RUN”: Fan running indicator light turns on when the fan is running and turns off when the fan is turned off
