General description Fast charging version of PWM speed regulator suitable for high power and multi-device application scenarios. This controller supports larger current and higher power limits, making it ideal for violent high-power or large numbers of PWM fans and water pump speed adjustment requirements. It can control more than 15 common 12V 0.2A PWM fans simultaneously, with a fan speed adjustment range of 0-100%. Technical specifications Output voltage: 12V Output current: PD up to 3A, QC up to 1.5A PWM frequency: approximately 25KHz Input port: USB Type-C female port Output port: PWM 4Pin (KF2510) Speed adjustment range: PWM duty cycle 0-100% Color: Black Material: PLA Type: 1 to 2 Adapter Cable Installation Connect the USB Type-C female input port to a PD/QC fast charging power supply. Connect the PWM 4Pin output port to the PWM fans or water pumps. Usage To operate the speed controller, turn the knob clockwise to increase speed, counterclockwise to decrease speed, and turn the
