Description This is a three-channel fan speed/temperature controller, for 4-wire computer fans. The first channel supports automatic temperature detecting and fan speed adjust. The second and third channel need external potentiometer adjust. When fan stops, first channel and second channel can trigger buzzer to sound alarm. Specifications: PCB Size: 50*43*13mm (L*W*H) Mounting Hole: 44*37mm, diameter 3mm Working voltage: DC12V Load capacity: each channel max output current 5A, total max current 9A Output range: first channel 20%~100% or 40%~100% (TFL=ON), second and third channel 10%~100% (Note: the ranges are only PWM range, in actual operation, depending on specific fans, control effect may fluctuate). Temperature Probe: 50k B = 3950 (Error of 3%, length 8cm, the head of the maximum temperature 125 ) Temperature Precision Range: depends on precision of temperature probe (Precision range 3%~5%) Minimum fan-stop alarm speed: 700 to 800 rpm Buzzer: Line length 10cm, 12mm diameter Function Details: Please look at the control switch area on the board: TFL : PWM setting for temperature control: when set at ON, minimum speed of FAN1 is 40%; when set at OFF, minimum PWM of FAN1 is 20% TP1 TP2 : control fan speed-up in relation to temperature. Setting details: TP1 OFF, TP2 OFF: speed-up temperature: 35 Celsius Degrees; Full Speed temperature: 45 Celsius Degrees. TP1 ON, TP2 OFF: speed-up temperature: 40 C; Full Speed temperature: 50 C. TP1 OFF, TP2 ON: speed-up temperature: 50 C; Full Speed temperature: 70 C. TP1 ON, TP2 ON: speed-up temperature: 60 C; Full Speed temperature: 90 C. When temperature is below the speed-up temperature, fan runs at minimum speed. When temperature is over full speed temperature, fan will run at full speed. BF1, BF2: the two are respectively fan-stop-alarm switch for FAN1, FAN2. When switched on, if a fan stops, the matching switch will trigger buzzer and LED to alarm. If both switches are on, then, when either of FAN1,FAN2 stops, or both stops, alarm will turn on.
