4-Wire Fan Speed Regulator DC 12-24V 1.5A Dual-Channel PWM Speed Controller Low Voltage Motor Speed Controller Module

Quantity : 1 High-concerned chemical : none Package : TQFP is_d : Yes Supply Voltage : DC 12-24V Type : Voltage Regulator Brand Name : diymore Origin : Mainland China Condition : New

Product Features 1. Using PWM technology, this speed regulator enables precise control of fan speed 2. Supports simultaneous connection of two 4-wire fans, allowing synchronized control of both fans 3. Users can manually adjust fan speed and set their own speed levels 4. Includes a reverse connection protection circuit to effectively prevent damage from incorrect wiring 5. Real-time LED status display; the faster the speed adjustment, the brighter the light

Product Description This module is specifically designed for standard Intel 4-wire fans and outputs a pure PWM speed control signal. Fans must have their own speed control circuitry; 2-wire and 3-wire fans are not compatible. Unlike PWM speed control via the power supply, this method avoids abnormal noise and stuttering caused by intermittent power supply, ensuring smoother fan operation. The blue and black wires are the speed control terminals (corresponding to pins 1–4): shorting them sets the minimum speed, while leaving them unconnected sets the maximum speed. This module is compatible only with standard Intel 4-wire fans.
