Aideepen | New Dual-Channel 4-Wire Fan Speed Regulator DC 12-24V 1.5A PWM Speed Controller With Reverse Polarity Protection LED Display

Product Features1. Through PWM technology, this speed controller can achieve precise control of fan speed2. Support simultaneous connection of two four wire fans, which can be synchronously controlled3. Users can choose to manually adjust the fan speed and set the fan speed themselves4. Add anti reverse protection circuit to effectively prevent damage caused by misconnection5. Real time LED status display, the faster the speed, the brighter the lightProduct IntroductionThis module is designed specifically for standard Intel 4-wire fans and outputs pure PWM speed control signals. The fan needs to come with its own speed control circuit, and 2-wire 3-wire fans cannot be used. It is different from the PWM power supply speed regulation method, which avoids abnormal noise and operation lag caused by intermittent power supply, ensuring that the fan runs more smoothly. The blue and black lines are the speed control terminals (corresponding to pins 1-4): a short circuit is the minimum speed, and no short circuit is the maximum speed. This module is only compatible with Intel standard 4-wire fans.Product SpecificationsWorking voltage: DC 12-24VAdjustment method: potentiometerMaximum output current: 1.5AOutput frequency: 15KHZDuty cycle 10-100%Packing ListFan speed regulator * 1
