General description This PWM Speed Controller is a fast charging version designed for high power and multi-device applications. It supports larger current and higher power limits, making it ideal for controlling multiple PWM fans and water pumps simultaneously. With a built-in PD/QC fast charging protocol trigger, it can output significant power depending on the charging head used. Technical specifications Output voltage: 12V Output current: PD up to 3A, QC up to 1.5A PWM frequency: approximately 25KHz Speed adjustment range: PWM duty cycle 0-100% Input port: USB Type-C female Output port: PWM 4Pin (KF2510) Color: Black Material: PLA Compatibility and accessories Designed specifically for 12V 4-wire PWM fans and water pumps Includes 1 x Fan Speed Controller Includes 1 x Adapter cable USB cable not included (must be provided by the user) Installation Connect the USB Type-C input to a compatible PD/QC fast charging power supply. Connect the PWM fan or water pump to the PWM 4Pin output.
