Fast charging version of PWM speed regulator suitable for high power/multi-device application scenarios Support larger current and higher power limit Built-in PD/QC fast charging protocol trigger (only supports PD/OC fast charging charging head or power bank as power supply device) With a PD fast charging head over 45 watts, it can output up to 36 watts (12V3A).With the standard OC fast charging head, it can output 18 watts (12V 15A) Applicable scenarios: violent high-power or large number of PWM fans and water pump speed adjustment requirements. The common 12V0.2APWM fans can control more than 15 fans at the same time. PWM duty cycle (0-100%) The input terminal is TYPE-C female port Designed specifically for 12V 4-wire PWM fans/water pumps The output end is a small 4Pin socket (KF2510) Built-in PWM signal generation circuit Integrated solution, integrated power supply + speed regulation Operation : Turn the knob clockwise to increase speed, counterclockwise to decrease speed, and turn the knob fully counterclockwise to close. NOTE: Only supports standard PD/QC fast charging protocol power supply equipment. Fast charging version of the PWM governor does not offer USB cable, need to self-match high current on the USB cable quality requirements are high, please choose high quality cable. It is recommended to use standard PD/QC fast charger head or charging treasure (with 12V gear). Specification: Product name: PWM speed regulator (fast charging version) Support protocol PD/QC fast charging protocol Output voltage: 12V PWM frequency: about 25KHz Output current: PD up to 3A, QC up to 1.5A Input port: USB TYPE-C female port Output port: PWM 4Pin(KF2510) Speed adjustment range: PWM duty cycle 0-100% Material: PLA colour: Black Package Contents: 1 x PWM Speed Controller Only the above package content, other products are not included.
