DC 12V 3A 4Pin PWM Fan Speed Control Module Automatic Temperature Controller NTC Sensor for 3000mA Fan

1.Description:
  Fan speed control module automatic temperature controller can automatically adjust the speed of fan according to the actual temperature. When the temperature is too low, it can made the fan stop running.

2.Feature:
 1>.High quality.
 2>.Good materials.
 3>.Beautiful appearance.
 4>.To shut down the fan at low temperatures.
 5>.Convenient to wire.
 6>.Adjust the speed of PWM fan.

3.Parameter:
 1>.Supply Voltage: DC 12V
 2>.Voltage Range: DC 8~16V
 3>.Cricuit Dissapation: <40mA
 4>.Current of Fan: =<3.3A
 5>.PWM Range: 1%~100%
 6>.PWM Frequency: 25KHZ(+/-1KHZ)
 7>.PWM Signal Amplitude: 5V
 8>.Measured Temperature Range: -9.9~99.9℃
 9>.Temperature Measurement Error: 0~50℃ less than 1.2℃; other temperature ranges less than 2℃

4.Temperature Parameter Description:
 1>.Acceleration temperature("L**"  *represent the number)
  1.1>.The range of it is 5~94.
  1.2>.If the actual temperature is more than acceleration temperature, PWM output pulse increase.
 2>.Full-speed temperature("H**")
  2.1>.The range of it is 10~99.
  2.2>.If the actual temperature is more than full-speed temperature, PWM output pulse reach 100%.
  2.3>.The fan rotate at the fastest speed.
 3>.Closing temperature("C**")
  3.1>.The range of it is 0~92.
  3.2>.If this value is above zero, the equipment will shut down the fan at low temperatures.
  3.3>.If the actual temperature is less than closing temperature, the fan and PWM will turn off at the same time.
  3.4>.After shutdown, if the temperature continues to rise to acceleration temperature, the fan restarts.
  3.5>.However, if this value is zero, the equipment will not shut down the fan at low temperatures.
 
5.Note:
 1>.Supported Model:
  1.1>.It is suitbale for four-wire standard PWM signal control fan to adjust the speed.
  1.2>.The default signal is 25KHZ 5V.
  1.3>.It supports four-wire fans, such as fans of case or CPU.
  1.4>.However, it does not supply to the speed regulation of two-wire and three-wire fans.

2>.About temperature:
  2.1>.The difference between acceleration temperature and full-speed temperature should more than 5 degrees.
  2.2>.The difference between closing temperature and acceleration temperature should more than 2 degrees.
  2.3>.If the preceding two conditions are not met, the parameters are automatically changed to the other two parameters.

6.LED Display Instruction:
  1. Three digtal tube: To display parameters and numerical values.
  2. LED"×10 RPM": It is the speed light. The value is one-tenth of the fan speed.
  3. LED"℃":It is the temperature indicator light. It displays the actual temperature measured by the probe.
  4. LED"RUN": It is the running indicator light. It turns on when the fan is running and turns off when it stops.

7.Button Instruction:
 1>."+"/"-" button
  1.1>.At run time, the button is used to switch the display.
  1.2>.When parameter setting, the button is used to increase/decrease the value. s

 2>."OK" button
  2.1>.When working, tap to enter the manual speed control settings.
  2.2>.The range of it is 1~100(%).
  2.3>.Tap again to save and then exit this mode.
  2.4>.When working, press longer to enter the temperature settings.
  2.5>.You can modify the parameter by tap "+"/"-" button.
  2.6>.Tap "OK" button again to switch the setting project.
  2.7>.Then set acceleration temperature, full-speed temperature and closing temperature.
  2.8>.Finally tap "OK" button again to save and then exit this mode.
  2.9>.In power off, press "OK" button longer to enter function settings.
  2.10>.You can modify the parameter by tap "+"/"-" button.
  2.11>.Tap again to save and then exit this mode.
  2.12>.In power off, press "OK" button longer to enter minor settings.
  2.13>.It is used to modify the output direction of PWM.
  2.14>.The output direction can be divided into two, forward and reverse; shown as "P 1" and "p-1".
  2.15>.Tap "OK" button again to save and then exit this mode.

8.Package:
  1 pcs fan speed control module automatic temperature controller
