ITEM NAME:DC 12v pwm pc cpu fan temperature control speed controller module 3C Specifications: Working voltage:DC12V Circuit load capacity: maximum current per output 5A, the bus currents up 9A Output Range: The first channel 20% -100%, or 40% -100% (TFL = ON) The second channel and the third channel 10% -100% (Note: Above range only for PWM range, the actual control effect will vary depending on the fan.) Temperature probe parameters: 50K B = 3950 Thermostat temperature zone error: error depending on the temperature probe, generally 3-5% Stall alarm minimum speed: 700-800 rpm Function setting switch Description: TFL (No. 1): The lowest temperature channel PWM setting, when ON state FAN1 PWM minimum is 40%, when OFF the minimum PWM of FAN1 is 20%. TP1 TP2 (No. 2,3): Temperature channel control temperature zones are interpreted as follows (need to used with the temperature probe): TP1    TP2    Accelerating temperature    Full speed temperature OFF    OFF    35 °    45 ° ON    OFF    40 °    55 ° OFF    ON    50 °    70 ° ON    ON    60 °    90 ° When the temperature lower than the accelerated temperature, then output at the minimum rotation speed; when it exceed over the full temperature, then always output at full speed. BF1 BF2 (No. 4,5): corresponds FAN1 FAN2 stall alarm function switch, when the corresponding open channel fan break down, the controller will alarm with soundand light (works with buzzle), alarm will automatically eliminated when the fan is rotated recovery . If BF1 and BF2 both are open (ON), the FAN1, FAN2 have any one or both stops, the controller will alarm! Package Included: 1 x Speed controller 1 x Temperature probe 1 x Buzzle.TFL (No. 1): The lowest temperature channel PWM setting, when ON state FAN1 PWM minimum is 40%, when OFF the minimum PWM of FAN1 is 20%. Stall alarm minimum speed: 700-800 rpm. Thermostat temperature zone error: error depending on the temperature probe, generally 3-5%.
