PWM Extractor Fan Speed Controller PART2 for 3D Printer Enclosure - Tukkari, PrusaBox, Lack Box

Part 2 Demonstration how a PWM fan controller can be fitted to a 3D printer enclosure to proportionally control the speed of the extractor or any cooling fans Useful Links: Face plate for my controller box as per the video - https://www.printables.com/model/2781...

Working Voltage: DC 11V ~ 55V 3. Working Current: 0.1A (MAX) 4. Fan Current: 5A (MAX) 5. PWM Range: 5% ~ 100% or 0% 6. PWM Frequency: 20KHz / 2.5KHz 7. PWM Signal Amplitude: 10.5V (no load) 8. Temperature Measurement Range: -9.9℃ ~ 99.9℃ 9. Working Temperature: -25℃ ~ 85℃ 10. Working Humidity: 5% ~ 95% RH 11. Sensor Wire Length: 1 meter 12. Size: 70.5 x 40.5 x 13.5mm 3. If additional fans need to be shut down at same time as the primary PWM fan, they can be controlled to cut off power through the external relay trigger circuit, supplied by the 'relay' header on the PWM controller's PCB. 1. Power interface: The main power input interface (11v ~ 55v): + | - | Supplies the main power to the control board PCB, also providing the power to pass through to the fan output interface. 4. Alarm signal port (2-pin): High-level output during normal operation, low-level output when the fan is abnormal. 5. Relay interface (2-pin): Expansion interface. Drives a 9V or 12V relay, which can be used to control an addtional fans power circuit, when the fan control stops (the 'RUN' LED indicator turns off), the relay opens. 2.1 With the PCB powered ON, short-press the OK button to enter the inherent PWM output setting, the range is 5% ~ 100%, short-press again to save and exit. 2.2 With the PCB powered ON, long-press 'OK' button to enter the temperature parameter setting. After entering, modify the first parameter (L__) by pressing the + Button and - Button. When the 'L' setting is as desired (e.g. L35), short-press the 'OK' Button to save and move to the next parameter adjustment (H__), modify by pressing the + Button and - Button. When the 'H' setting is as desired (e.g. H45), short-press the OK Button to save and move to the next parameter adjustment (C__), modify by pressing the + Button and - Button. When the 'C' setting is as desired (e.g. C25), short-press the OK Button to exit the temperature parameter adjustment mode. L = Acceleration Temperature | H = Full Speed Temperature | C = Turn-off Temperature 3. Shut-down temperature (the display showing "C**"): Low-temperature shutdown temperature. The range is 0℃ ~ 92℃. When this value is set to over 0, the low-temperature shutdown function is enabled. When the temperature is lower than this temperature, the output is turned off (PWM signal and extended relay output are turned off at the same time). When the temperature rises above the acceleration temperature in the off state, the fan restarts and changes speed with the temperature, if the shutdown temperature is set to 0, the low temperature shutdown function is disabled, and the PWM and extended relay output interfaces will always output. 4. The difference between the acceleration temperature and the full speed temperature must not be lower than 5℃, and the difference between the closing temperature and the acceleration temperature must not be lower than 2℃. If the value will break the above temperature difference when modifying the parameters, the program will automatically adjust the other two parameters. 1. "X10 RPM": Speed unit displaying. When this light is on, the display is currently indicating the fan speed, which is the value after the speed divided by 10. For example, if the display indicating is 256, the actual fan speed is 2560 RPM (revolutions per minute). 3. "RUN": Fan running indicator. This light illuminates when the fan is running, and goes out when the fan is off.
