Package: 1 piece of PWM fan thermostat

The product will be upgraded constantly, the appearance and color may be changed, please don't mind. And take a consideration before place the order if you have request for color or appearance.

Parameters:
Circuit board size: length 50mm * 43mm * 13mm,
Fixed particle hole position: 44mm*37mm,
Diameter: 3mm
Working voltage: DC12V
Circuit load capacity: each output maximum current 5A, total current up to 9A

Function setting switch description:
TFL (No. 1): The lowest PWM setting of the temperature control channel, the lowest PWM of FAN1 is 40% in the ON state, and the lowest PWM of FAN1 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 (it needs to be used with a 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℃

If the temperature is lower than the acceleration temperature, the output will be at the lowest speed, and if the temperature exceeds the full speed, the output will always be at full speed.
BF1 BF2 (No. 4, 5): Corresponding to the FAN1 FAN2 stop alarm function switch, when the corresponding is turned on, the channel fan fails and stops, the controller will sound (need to be equipped with a buzzer) and light alarm, and the fan will resume rotation The alarm is automatically eliminated. If both BF1 and BF2 are turned on (ON), any one or both of FAN1 and FAN2 will stop, and the controller will alarm!

Parameters:
Circuit board size: length, width and height 50mm*43mm*13mm,
Positioning hole position: 44mm*37mm,
Diameter: 3mm
Working voltage: DC12V
Circuit load capacity: the maximum output current of each channel is 5A, and the maximum bus current is 9A
Output range: the first channel 20%-100% or 40%-100% (TFL=ON)
The second and third channels 10%-100%
Note:
The above range is only the PWM range, the actual fan control effect will vary according to different fans.
Temperature probe parameters: 50K B=3950
Temperature control temperature zone error: according to the temperature probe error, generally 3-5%
Minimum speed for stall alarm: 700-800 rpm
