10pcs DC 12V 3Pin PWM PC CPU Fan Temperature Control Thermostat Speed Controller Classification description: 1. Input line: Red and black power cord is only welded 12V positive and negative power cord head, as a general use. The three-wire connector is equipped with a 2510-3P plug for the speed detection of the three-wire fan port of some motherboards, and the large 4P interface is convenient for taking power from the chassis power supply. 2. Temperature probe: The small blackhead has a short head and low heat capacity. It is suitable for testing narrow spaces and air temperatures, and the response is relatively fast. The ring probe is housed inside a circular metal head with a diameter of 4.2 mm. It is suitable for mounting on the surface of a radiator or other heat-generating object with screws. Demo video link (please copy the link to the browser to view): http://v.youku.com/v_show/id_XMzEzMTcxMzAyOA==.html index: Operating voltage: DC12V can work in the range of 9-14V Fan interface: 2510-3P bend (needle spacing 2.54mm) Fan current: within 0.8A Protection: Input reverse connection protection Note that there is no output overload protection! ! ! Please note that the output should not be shorted or overloaded. Drive output range: 5% -100 Some fans may not turn when low output. Please use the position where the fan can be started. Working temperature: -20 ° C to 60 ° C Temperature probe parameters: NTC 50K B=3950 Probe temperature resistance: small black head 120 ° C, ring probe 110 ° C Board size: 43mm*18mm*9mm (without protruding interface), fan interface extends 8mm Set the factory default values of the parameters: low speed 20%, acceleration temperature 30 °C, acceleration width 5 °C, no shutdown output. At this temperature setting, holding the thermal probe with your hand will accelerate after a while, and the probe clip will reach full speed within 2 minutes if it enters the armpit. The controller is designed as a combination of manual control and automatic temperature control control: 1. It is pure manual when the temperature probe is not installed: click/double-click (do not double-click the speed too fast) button up/down position. Each time you change the gear position, it will continue to run for 20 seconds to automatically store the gear position. In 20 seconds, the indicator light 2 will flash rapidly (when the temperature control is invalid), when the flashing is stopped, it means that the gear position has been stored. When the position cannot continue to increase/cannot continue to decrease, the indicator 3 / 1 will be on constantly. 2. After installing the temperature probe, the speed of manual speed regulation is the initial low speed (bottom line speed). When the temperature exceeds the acceleration temperature, the fan speed increases smoothly with the temperature rise, when the temperature reaches and exceeds the acceleration temperature and the acceleration width. And (that is, full speed temperature), the fan is at full speed. Set the acceleration temperature and acceleration width parameters as shown in the following setting diagram. In the figure, the 1 2 3 number indicates that the indicators on the board are on (red) and off (white) are displayed in binary order: 3. Fan shutdown policy setting: First, power off and remove the fan. Press and hold the setting button to power on the controller. Keep the setting button pressed and held (about 3 seconds) until the three lights become double flash and release the button. The indicator light becomes single. The lamp double flashes, which means that it enters the mode setting state. The controller is divided into three working modes, corresponding to the double flashing of the indicators 1, 2, and 3. Press the button to switch. After setting, press and hold the button to save and exit the setting mode and automatically return to the normal working state. The three working modes are: br> 1. Do not shut down the output. 2. Turn off the output when the acceleration temperature is 2 degrees Celsius below. 3. Turn off the output when the acceleration temperature is below 5 degrees Celsius. Example: Set the acceleration temperature to 35 degrees Celsius, the acceleration width to 10 degrees Celsius, and the shutdown strategy mode 3 (below the acceleration temperature of 5 degrees Celsius). After this setting, the fan does not turn when the temperature is lower than 35 degrees at the time of power transmission. When the temperature rises to 35 degrees, the fan starts up according to the manual setting. The temperature continues to rise and the speed is gently accelerated, reaching full speed at 45 degrees. When the temperature drops to between 35 and 30 degrees, the fan always runs at the manually set speed, and the fan stops below 30 degrees. Note that the fan shutdown strategy is hysteresis control, which can effectively prevent the fan from repeatedly switching around the critical point. For example, after the above setting, the temperature rises to 35 degrees to start the fan, and the cooling temperature is lower than 30 degrees to turn off the fan. Tips for using: 1. Since most fans can run at low output but can't start, when setting the minimum temperature control speed, you should first adjust to the minimum, and let the fan stop by hand, then increase the output step by step until the fan starts normally. Bit, do not lower than this position after the actual setting, otherwise the fan may not start at low speed. Warranty instructions (cheap bare board products): 1.
