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 or power bank as power supply device), if With a PD fast charging over 45 watts, it can output up to 36 watts (12V3A); if With the standard OC fast charging , 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. Fan speed adjustment range 0-100%. This governor input port is USB Type-C female.Output is standard PWM 4pin fan port. Designed specifically for 12V 4-wire PWM fans/water pumps. Built-in PWM signal generation circuit. Integrated solution, integrated power supply + speed regulation. Operation method: 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. The fast-charging PWM speed regulator does not come with a USB cable, so you need to provide one yourself. For high currents that require high quality USB cables, please use high-quality cables. It is recommended to use standard PD/QC fast charger or charging treasure (with 12V gear).
