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

Product features:1. Support DC 5-12V wide voltage input range, suitable for a variety of different voltage requirements of equipment, improve the flexibility of use2. Manually adjust the fan speed for easy operation3. With the switch function, users can directly control the start and stop of the fan, convenient and fast, effectively extend the life of the fan and equipment4. The use of advanced PWM speed regulation technology can not only reduce the noise of the fan during operation, but also maintain a good heat dissipation effect at low speed to create a quieter working or living environment5. Four-wire interface compatible with mainstream chassis fans, easy to achieve fan speed control.Product parameters:Operating voltage: DC5-12V, can work at 5-15V voltage, please note that the fan voltage is consistent.Fan current: not greater than 4A. The current is limited by switches and connectors, and can be expanded by connecting power cables separately.Circuit board loss: less than 20mA without fanPWM signal mode: 5V20.5KHz for 12V power supply and 4V20.5KHz for 5V power supplyPWM signal output range: 1%-100Output port type: conventional CPU, chassis fan jack, pin spacing 2.54mmCircuit size: circuit board 22mm*20mm, knob screw extension 15mm, installation hole 7mmType: Red and Black cable /3P plug cable (optional)Function description:Pay attention to the positive and negative terminals and power supply voltage, connect the power fan can be used, the potentiometer in the end counterclockwise off, clockwise in the end for the maximum output. If the fan speed changes in the opposite direction of the adjustment, it indicates that the fan is an anti-timing fan, and the (PF) setting point needs to be short-connected with solder. Power off before operation to avoid damage! After short-circuiting, the PWM signal changes in the reverse direction with the adjustment, then the reverse sequential fan can realize the positive adjustment.Note: This is a four-wire PWM fan governor, can only control four-wire fans that support PWM speed regulation, such as many 12V four-wire chassis or CPU fans, can not control 2-3 wire fans!!! The default power-on PWM is adjusted from 1%.Shipping list：fan Governor *1
