Features:
1. Use high-quality materials with guaranteed quality
2. Small size and exquisite appearance
3. 2-3-wire fan temperature control speed controller
4. Support 0.2-2A current range fan
5. Wide application range
Parameter:
Design power supply voltage: DC12V
Voltage range: DC9.5-14.5V (circuit working voltage, please pay attention to the fan voltage range)
Circuit self consumption: less than 70mA (tested at 12V)
Fan current: 0.2-2A (control effect deteriorates below 0.2A)
Temperature measurement range: -9.9-99.9 ℃
Temperature measurement error: within the range of 0-50 ℃, the error is less than 1.2 ℃, and in other ranges, the error is less than 2 ℃. Circuit board size: 70 * 19 * 11 (length, width, height, mm, excluding protruding interfaces)
Default factory settings: acceleration (start) temperature 30 ℃, full speed temperature 35 ℃, shutdown temperature 28 ℃, basic output 20
Key Description:
Button ‘+’ and ‘_’: Switch the display during operation, and increase the value during parameter setting (long press to continuously increase or decrease)
The ‘OK’ button has two functions:
1. In working mode, short press to enter the inherent output setting, that is, manual speed regulation setting, with a range of 1-100. Short press again to save and exit.
2. In working mode, long press to enter the temperature parameter setting. After entering, use the ‘+’ and ‘-‘ buttons to modify the parameters, and short press the ‘OK’ button to switch between the setting items. Set the acceleration temperature ‘L * *’, full speed temperature ‘H * *’, turn off temperature ‘C * *’, and briefly press the ‘OK’ button again to save and exit the settings. If there is no operation for a long time, the system will automatically exit without saving data.
Detailed description of temperature parameters:
L_ * * ‘: Acceleration temperature, range 5-94 ℃. When the temperature rises and exceeds this temperature, the fan voltage increases with the temperature.
‘H * *’: Full speed temperature, range L * *+5-99 ℃. When the temperature reaches or exceeds this temperature, full output, and the fan is at full speed.
‘C * *’: Turn off the temperature, with a range of 0-L * * -2 ℃. When this setting is greater than 0, the low-temperature shutdown function is enabled. When the temperature drops below this temperature, the fan output is turned off, the fan stops running, and the ‘RUN’ light goes out. When the fan is turned off and the temperature rises above the acceleration temperature ‘L * *’, restart the fan output. If this parameter is set to 0, the low-temperature shutdown function will fail, and it will always output according to the inherent output value at low temperatures.
Note: The difference between ‘H * *’ and ‘L * *’ cannot be less than 5, and ‘C * *’ must be at least 2 below ‘L * *’. 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 ‘X10 RPM’: the speed unit light, which is on, and the Nixie tube displays the fan speed. The value multiplied by 10 is the actual measured speed. For example, if 256 is displayed, the actual fan speed is 2560RPM (r/min).
LED ‘℃’: temperature unit light, which lights up, and Nixie tube displays the temperature measured by the current probe.
LED ‘RUN’: Fan running indicator light, lit when the fan is running and turned off when the fan is turned off.
