Aideepen | DC 5-12V Manual 4-Wire PWM Fan Governor Module Switch Chassis Speed-Control Motor Noise-Reduction Controller Board Power Supply

Product Highlights:1. Supports a wide input voltage range of DC 5-12V, suitable for various devices with different voltage requirements, enhancing flexibility of use2. Features manual speed adjustment for convenient fan rotation control3. Built-in switch function allows direct control of fan start/stop, offering quick operation and effectively extending fan and device lifespan4. Advanced PWM speed control technology reduces operational noise while maintaining effective cooling at low RPMs, creating a quieter work or living environment5. Four-wire interface compatible with mainstream chassis fans for effortless speed regulationProduct Specifications:Operating Voltage: DC 5-12V (can operate at 5-15V; ensure fan voltage consistency)Fan Current: ≤4A (subject to switch/connector limitations; may require separate power line expansion)PCB Self-Consumption: PWM Signal Mode: 5V 20.5KHz (12V power), 4V 20.5KHz (5V power)PWM Output Range: 1%-100%Output interface type: Standard CPU/chassis fan connector, 2.54mm pin pitchCircuit dimensions: PCB 22mm x 20mm, knob screw protrudes 15mm, mounting hole 7mmFunction 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.If fan speed changes in the opposite direction to adjustment, the fan is reverse-sequence type. Solder-bridge the (PF) setting point. Always disconnect power before operation to avoid damage! After bridging, the PWM signal will change in the opposite direction to adjustment, enabling forward control of reverse-sequence fans.Note:This is a 4-wire PWM fan controller. It can only control 4-wire fans that support PWM speed regulation, such as many 12V 4-wire case or CPU fans. It cannot control 2- or 3-wire fans!!!Default startup PWM starts at 1% and adjusts from there.Shipping List:Fan Controller x1
