Temperature setting: Set as follows:

Switch T1 Switch T2 Acceleration Temperature Full Speed ​​Temperature

OFF OFF 35 ° C 45 ° C

ON OFF 40 ° C 55 ° C

OFF ON 50 ° C 70 ° C

ON ON 60 ° C 90 ° C

Stall alarm setting: When the setting switch 3 is in the on position, it is the open and stop alarm function. Please check the three-wire fan which is in the middle of the output. When the fan speed is lower than the threshold, the alarm will resume until the fan speed is restored. stop. Do not need to stop the alarm function, please turn this switch OFF (non-ON)

specification:

Circuit board size: 50mm * 49mm * 15mm, positioning hole center distance: 44mm * 43mm, diameter: 3.2mm

Power supply voltage: DC12V can work safely between 9-14V, can not be used for car!

Power supply current: According to the total current of the fan, the board itself consumes less than 0.1A

Output adjustment range: 0% -100% of supply voltage (can be shut down **)

Temperature measurement error: According to the temperature probe error, generally 2-5% (with small black head inside the temperature probe error 1-2 degrees Celsius)

Maximum continuous output current: 5A

Maximum peak output current: 7A (3 minutes)

Efficiency: 93% (12V input 8V 4A output state test)

Stall alarm speed threshold: 450 + -50rpm (for 2-pole signal fan ***)

**: When the manual adjustment of the voltage is very low or 0V, which is equivalent to shutting down the fan, if the temperature control running on the basis of shutting down, due to reach the accelerated temperature output voltage increases linearly with the temperature, and fans need at least 3 -5V voltage to start running, so shut down the fan after the actual feeling of accelerated temperature (or called the starting temperature) than the set temperature in the acceleration zone temperature is high, and this use when the heat source may cause a small fan frequent Start and stop the resulting heat source component temperature fluctuation, caution.

***: More than 97% of the common fans are 2-pole signal fan, there are other 3-pole and 4-pole signal fan (very rare), 2-pole signal if it is less than 450 alarm, the 3-pole signal fan It is equivalent to less than 300 turn alarm.
