Fan Speed Controller, 0.5A Rated Current, 25KHz Frequency, DIY Water Cooling System Speed Controller

①. PWM Speed Controller designed for 12V 4-wire PWM fan/pump. ②. This PWM Speed controller support 12v standard fan speed control, also support computer water cooling PWM pump head speed adjustment. ③. This governor is recommended to control the output power within 7-8 watts (12V 0.6A). ④. This governor input port is USB Type-C female. Output is standard PWM 4pin fan port. ⑤. Built-in DCDC boost circuit(boost USB 5V to 12V). Built-in pwm signal generator (make it able to adjust speed). ⑥. Fan speed adjustment range 0-100%. ⑦. Turn the knob clockwise to increase the speed, Turn the knob counterclockwise to reduce the speed. ⑧. The application scenario of the governor design is mainly powered by the charging head/rechargeable battery, the common output capacity is generally 5V/2A, higher specifications are relatively rare, and the parameters of 12v/0.7A fan almost reach 5V/2A full power supply, while taking into account the small size of the PWM governor so limited cooling capacity. ⑨. It is recommended that the output current be controlled below 0.7A for short time use and below 0.5A for long time use. ⑩. Here means the current at the maximum speed, the fan current will vary proportionally according to the speed. ⑪. Input voltage: 5V ⑫. Output voltage: 12V ⑬. PWM frequency: about 25KHz ⑭.
