ITEM NAME:DC 12V PWM PC CPU Fan Temperature Control Speed Controller Board 5*4.3 UFI Descriptio n Description: Function Setting Switch Description: TFL (No. 1): The Minimum PWM Setting Of The Temperature Control Channel. The FAN1 Minimum PWM Is 40% In The ON State And The FAN1 Minimum PWM Is 20% In The OFF State. TP1 TP2 (No. 2, 3): The Temperature Control Channel Controls The Temperature Zone. The Specific Settings Are As Follows (Required With Temperature Probe): TP1 TP2 Acceleration Temperature Full Speed Temperature OFF OFF 35Â °C 45Â °C ON OFF 40Â °C 55Â °C OFF ON 50Â °C 70Â °C ON ON 60Â °C 90Â °C Below The Acceleration Temperature, The Output Is At The Lowest Speed, And When The Temperature Exceeds The Full Speed, It Is Always Output At Full Speed. BF1 BF2 (No. 4, 5): Corresponding To The FAN1 FAN2 Stop Alarm Function Switch. When The Corresponding Opening, The Channel Fan Will Stop And The Controller Will Sound (Requires A Buzzer) To Light The Alarm. The Alarm Is Automatically Eliminated. If Both BF1 And BF2 Are ON (ON), Then Either Or Both Of FAN1 And FAN2 Will Stop And The Controller Will Alarm! Basic Parameters: Board Size: Length, Width And Height 50mm*43mm*13mm, Positioning Hole Position: 44mm*37mm, Diameter: 3mm Working Voltage: DC12V Circuit Load Capacity: Maximum Output Current Of 5A Per Bus, Bus Current Up To 9A Output Range: 20%-100% Or 40%-100% Of The First Way (TFL=ON) Second And Third Roads 10%-100% Specifications: Material: Circuit Board Color: Blue Size: 50mm*43mm*13mm Package Included: 1* Computer Cooling Four Lines Note: The Above Range Is Only The PWM Range, And The Actual Fan Control Effect Will Vary Depending On The Fan. Temperature Probe Parameters: 50K B=3950 Temperature Control Temperature Zone Error: According To The Temperature Probe Error, Generally 3-5% Stop Alarm Minimum Speed: 700-800 Rpm We offer you what you need! 1PCS DC 12V PWM PC CPU Fan Temperature Control Speed Controller Board 5*4.3cm.The FAN1 Minimum PWM Is 40% In The ON State And The FAN1 Minimum PWM Is 20% In The OFF State. BF1 BF2 (No. 4, 5): Corresponding To The FAN1 FAN2 Stop Alarm Function Switch. The Alarm Is Automatically Eliminated.
