Aideepen | 4-channel DC12V 3A 4-wire PWM Fan Controller With Manual Knob Adjustment And Switch 5V 25KHZ Fan Speed Controller

Product Features:1. Supports variable speed control for 4 DC12V fans, meeting flexible adjustment needs in multi-fan scenarios2. Delivers 3A current output for stable operation of multiple fans, suitable for chassis and servers3. Employs four-wire PWM speed control technology with manual knob adjustment for precise airflow regulation4. Integrated switch function enables simple, intuitive operation for quick device startup/shutdown5. Reduces noise by lowering fan speed, providing a quieter working environmentProduct Specifications:Operating Voltage: DC12V, compatible with 8-15V input (ensure consistent fan voltage)Fan Current: Total maximum current for 4 fans: 3A (allow for operational margin)Board Power Consumption: PWM Signal Mode: 5V 25kHzPWM Output Range: 0%-100%Initial PWM Adjustment Range: 0%-60%Output Interface Type: 2510-4P staggered pins, standard CPU/chassis fan connector, 2.54mm pin pitchFunction Description:Ensure correct polarity and power supply voltage. Connect power and fan to operate. Turn potentiometer fully counterclockwise to off; fully clockwise for maximum output.The separate small adjustable resistor on the board (starting speed adjustment) regulates the initial rotational speed upon power-up.If the fan speed changes in the opposite direction to the adjustment, it indicates a reverse-sequence fan. Solder-bridge the (PF) setting point to enable forward adjustment. Always disconnect power before soldering to prevent damage! After bridging, the PWM signal will change in the opposite direction to the adjustment, allowing forward regulation of reverse-sequence fans.Important Notice:This is a 4-wire PWM fan controller. It can only control 12V PWM-compatible 4-wire fans, such as many 12V 4-wire case or CPU fans. It cannot control 2- or 3-wire fans!!!Package Contents:Fan Controller*1
