Wide power input, DC 5-30V, AC4-20V fan speed adjustable in four gears, 2. Automatic identification of positive and negative poles, high-speed rectification circuit, automatic identification of positive and negative poles for AC and DC, 3. Intelligent dedicated chip, dedicated intelligent temperature control fan control chip, wide voltage, low power consumption, safe and reliable, 4. The speed is adjustable in four gears, and the DIP switch controls the fan speed to be adjustable in four gears, taking into account the user's preference for noise and efficiency. 5. Easy to use, all solder-free ports are used, and it can be easily installed without a soldering iron. It is suitable for various industrial control power supplies and equipment, power amplifiers, computers and other occasions. Parameters: Product Name: Smart Fan Temperature Controller Working voltage: DC: 5V-30V, AC: 4V-20V Fan specification: DC 12V 24V 0.5A Product features: 4 gear fan speed adjustable Starting temperature: about 45-50C Size: about 50mm*25mm*12mm Notice: 1. The working temperature range of the probe is about 45-50C. Above this temperature, the fan will automatically rotate. Below this temperature, the fan will stop. The fan speed can be adjusted in four gears, which can effectively reduce energy consumption, reduce noise and prolong the life of the fan; 2. Please be sure to choose a fan with a current consumption of less than 500mA to reduce the heat generated by the control board; the input voltage should be as close as possible to the nominal voltage of the fan to obtain the best power utilization. Working principle: The working temperature range of the probe is about 45-50C. Above this temperature, the fan will automatically rotate. Below this temperature, the fan will stop. The fan speed can be adjusted in four gears, which can effectively reduce energy consumption, reduce noise and prolong the life of the fan. There may be some errors due to environmental factors, please pay attention; Fan Specifications: Please be sure to choose a fan with a current consumption of less than 500mA to reduce the heat generated by the control board, and the input voltage should be as close as possible to the fan's nominal voltage to obtain the best power utilization; Probe difference: Standard version, fixed with curing glue Wire lug version, use screws to fix it yourself Instructions for use: 1. The power input does not need to distinguish between positive and negative poles, and the circuit can automatically identify; 2. Please insert the fan after the positive and negative poles are correct, otherwise it will not work. If the order of the positive and negative poles of the fan is reversed, you need to replace the red and black wires of the fan or the terminals of the motherboard. Remember! 3. Please use cured thermal grease to fix the entire probe, or screw it tightly; to improve the speed and accuracy of temperature sensing. The package includes: 1X governor 1X probe _x000D_ _x000D_
