• DC12V Manual Four-Wire PWM Fan Speed Motor Controller Board With Knob Switch Electrical Equipment Governor Module Power Supply 1 Using fantastic materials, the quality is guaranteed 2 With switch, could be became off 3 The look of the product is beautiful 4 Simple and handy wiring five Stable functionality Product parameters: Working voltage: DC12V (can work under 8-15V voltage, please pay attention to a similar fan voltage) Fan current: no more than 3A, this latest is proscribed through switches and connectors, and can be expanded via strength lines by myself Loss of circuit board itself: lower than 20mA with out fan PWM sign mode: 5V25KHZ PWM signal output range: 0%-100% Start function PWM adjustment range: 0%-60% Output interface model: 2510-4P dislocation, conventional CPU, chassis fan socket, pin spacing 2 Function Description: Pay consideration to the superb and destructive poles and the ability supply voltage After the flexibility delivery fan is connected, it may be used The potentiometer is turned off counterclockwise to the end, and the clockwise finish is the maximum output A separate small adjustable resistor (starting velocity adjustment) on the board is used to adjust the rate of the just-open function If the speed change of the fan is contrary to the adjustment direction, it means that the fan is a reverse-sequence fan, and the (PF) setting point needs to be short-circuited with solder, and the flexibility should be bring to a halt before operation to circumvent damage! The short-circuited PWM sign adjustments in the opposite route with the adjustment, and the reverse-sequence fan can understand forward adjustment Precautions: This is a four-wire PWM fan pace controller It can only management 12V four-wire fans that support PWM pace legislation For example, many 12V four-wire chassis or CPU fans cannot control 2-3-wire fans Package List : Fan Speed Controller Controller X1
