Package Included: 1x Speed Controller with Sensor Probe This DC12V governor can be controlled according to the ambient temperature of the fan speed, no manual control, automatic stepless speed, the higher the ambient temperature, the faster the fan speed control, the ambient temperature is below the set the start temperature, the governor can control the fan stops running, in order to save power and eliminate unwanted noise generated by the fan. Variety of 2, 3, 4-wire 12V fans are applicable. Tips: 3-wire/4-wire fans only need to connect the fan's power cord to the controller. Board overall size: 1.77x1.0x1.18inch (LXWXH). M3 mounting hole. Features: 1. With power anti-reverse protection, power line reversed, the board will not burn. 2. New dual-mode function: fixed temperature mode and adjustable temperature mode. 3. Fit for 2,3,4 wire 12V fan, stepless temperature control can be achieved. 4. Single temperature sensor, easier to use, more responsive control. 5. On board there is a Mode Switch, the switch to the F position, the governor fixed temperature mode (The onboard potentiometer is useless); switch to the A position, the governor of temperature adjustable mode. 6. When the Mode Switch is in A position, the temperature adjustment potentiometer can use it, rotating the potentiometer, you can change the fan-start temperature. 7. Fixed mode temperature at 30 degrees, the fan speed control starts from 30 to 50 degrees fan speed linear increase, 50 degrees fan at full speed. 8. Adjustable mode start temperature range: 15 to 50 degrees, the full speed range of 35 to 70 degrees (start-up and full of temperature difference of 20 degrees). 9. The temperature sensor has a fixed head, sealed with epoxy resin, waterproof and moisture-proof, the default cable length is 300mm, and it can also be extended with a cable by yourself. The maximum operating temperature of the temperature probe is 110 degrees, exceeding this temperature, the probe will be damaged!

This DC12V governor can be controlled according to the ambient temperature of the fan speed, no manual control, automatic stepless speed, the higher the ambient temperature, the faster the fan speed control, saving energy and reducing noise.
Whether it is a 2-wire, 3-wire or 4-wire fan (only connect power cable), whether PWM or brushless fans, as long as the fan voltage is within 12V, current less than 1A, the governor apply! Also can drive a of fans (total current must<1A). [3-wire/4-wire fans only need to connect the fan's power cord to the controller]
The temperature sensor is connected with a cable in the form of mounting holes to facilitate detection of the temperature specified temperature point. Temperature probe is sealed with epoxy resin, waterproof and moisture-proof, the temperature probe maximum use temperature of 110 degrees. Sensor probe length 300mm/11.5inch.
Dual working mode optional, fixed starting temperature or adjustable starting temperature. Fixed mode temperature and temperature of 30°C(86°F), the governor control fan start, 30 to 50 degrees fan speed linear increase, 50°C(122°F ) above the fan at full speed. Adjustable mode start-up temperature range 15 to 50 degrees, full speed range of 35 to 70 degrees (start and full-speed temperature difference of 20 degrees).
Board size 1.77x1.0x1.18inch/ 45x25x30mm (LXWXH), M3 mounting hole. ( Note that It is best to read the main picture instructions before use)
Used this for controlling venting fans in utility switching boxes in the desert. I need the speed of the fan to adjust to the wildly fluctuating temperatures of the environment, and keep the temps from soaring inside the box.
