DC 8-24V 5A 4-Wire Fan Speed Regulator, PWM Controller for DC Brushless Motor, Adjustable 0-100% Duty Cycle, 22KHz, 60W/120W

This DC 8-24V 5A 4-wire fan speed regulator is a PWM controller designed for compatible brushless DC motors and cooling fans. It provides smooth and adjustable speed control through a 5V square-wave PWM signal with an adjustable duty cycle from 0% to 100%. With an operating voltage range of DC 8V to 24V and a rated current up to 5A, this controller is suitable for a wide range of low-voltage brushless motor and fan speed control applications. It supports up to 60W at 12V and 120W at 24V, making it a practical solution for DIY electronics, cooling systems, and custom motor control projects. The module operates at approximately 22KHz frequency for stable control performance. It features low power consumption of about 20mA and nearly 0mA quiescent current when powered off. The compact PCB measures 41 x 32.8mm, and the speed-regulating potentiometer has a 15mm shaft length for easy panel mounting.
