Ziqqucu PWM โมดูลควบคุมอุณหภูมิพัดลม CPU อัตโนมัติ สําหรับเครื่องขยายเสียง คอมพิวเตอร์ DC 12V

Features: 1.Design of special temperature control chip 2.Linear adjustable temperature 3.Wide power input DC5-30V AC: 4-20V 4.More current supports more fans 5.The fan speed is adjustable in four gears Parameters: Product name: intelligent fan temperature controller Working voltage: DC12V (DC) Fan specification: DC 12V Product features: temperature linear adjustable Temperature control range: about 45-100 ℃, adjustable The size is about 43.6mm * 22mm * 13mm 1. The circuit has a constant resistance, and the fan will turn at low speed when it is powered on. When the temperature control probe detects that the temperature is higher than the preset value, the circuit will control the fan speed to accelerate until the temperature is constant. If the temperature continues to rise, the fan will continue to accelerate to close to full power； 2. Applicable occasions: various industrial control power supplies and equipment, power amplifiers, computers, etc； 3. Be sure to select fans with current consumption less than 200mA to reduce the heat output of the control panel. 4. The length of the temperature probe wire is about 10cm. Unless you buy the finished product, you need to weld the picture by yourself. It is only for example. When the probe is working, please apply the heat sink (prepared by yourself), and press the heat sink tightly to accurately control the temperature. Instructions: 1. After the assembly of other parts except the temperature probe, carefully check whether there is reverse welding and dislocation, and whether there is tin on the back； 2. After connecting to DC 12V, the fan should be able to rotate at low speed, please note that the positive and negative poles should be correct, and then the tweezers should short circuit the probe interface, and the fan can rotate at full speed； 3. Install the temperature control probe, manually raise the measured heating temperature to the maximum, adjust the precision fine tuning potentiometer, and let the fan rotate at full speed, that is, the commissioning is completed. If necessary, use a multimeter to monitor the output voltage to improve the accuracy. Working principle: The circuit has a constant resistance, and the fan will turn at low speed when it is powered on. When the temperature control probe detects that the temperature is higher than the preset value, the circuit will control the fan speed to accelerate until the temperature is constant. If the temperature continues to rise, the fan will continue to accelerate until it is close to full power； Applicable occasions: Various industrial control power supplies and equipment, power amplifiers, computers, etc； Fan specification: Please be sure to select fans with current consumption less than 200mA to reduce the heat output of the control panel. This control panel is only applicable to DC 12V power supply and fans, and other specifications are strictly prohibited； Package include： Package 1: 1X fan module Complete set of parts Package 2: 1X fan module
