PWM Speed Controller 4Pin Fan Governor USB TYPE-C Power Supply DIY Wat

PWM Speed Controller 4Pin Fan Governor USB TYPE-C Power Supply DIY Wat Description

Features: This PWM Speed controller support 12v standard fan speed control, also support computer water cooling PWM pump head speed adjustment.
This governor is recommended to control the output power within 7-8 (12V 0.6A)
This governor input port is USB Type-c female. Built-in DCDC boost circuit(boost USB 5V to 12V). Built-in pwm signal generator ( to adjust speed)
Output is standard PWM 4pin fan port, Fan speed adjustment range 0-100%, Turn the knob clockwise to increase the speed, Turn the knob counterclockwise to reduce the speed, Turn counterclockwise to close the output.
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.

It is recommended that the output current be controlled below 0.7A for short time use and below 0.5A for long time use.
Here means the current at the maximum speed, the fan current vary proportionally according to the speed.
The rated current of common computer cooling fans on the market is generally less than 0.2A, and rarely exceeds 0.3A. Fans with higher current are generally used for industrial.
The governor can also control multiple fans simultaneously with a single tow line(could check the wires we sell).
There together have a short Type C wire to supply power(could use other Type C when length is not enough).
