PWM Speed Controller 12V 4-Pin 0-100% Adjustment USB-C Powered for Fan Pump Description

Product Details ①. Designed for 12V 4-wire PWM fans/pumps, supporting both standard fan speed control and computer water cooling PWM pump head speed adjustment ②. Built-in DCDC boost circuit converts USB 5V to 12V, and built-in PWM signal generator enables 0-100% speed adjustment via knob ③. USB Type-C female input port and standard PWM 4pin fan output port for easy connection ④. Compact plastic design in black, suitable for power supply via charging head or rechargeable battery Specification ①. Material: Plastic ②. Colour: Black ③. Input voltage: 5V ④. Output voltage: 12V ⑤. PWM frequency: About 25KHz ⑥. Output current: Rated 0.5A, maximum 0.7A ⑦. Speed range: PWM duty cycle 0-100% ⑧. Input port: USB TYPE-C female port ⑨. Output: PWM 4Pin Package Contents ①. 1 x PWM Speed Controller ②. 1 x USB to TYPE-C power supply cable Warm Tips ①. It is recommended to control the output power within 7-8 watts (12V 0.6A) ②. For short time use, output current should be controlled below 0.7A; for long time use, below 0.5A (current at maximum speed, varies proportionally with speed) ③. Light reflection and different displays may cause slight color difference from the real item ④. The measurement allowed error is +/- 1-3cm
