• DC 12V Manual 4 Pin PWM Fan Speed Motor Controller Board With Knob Switch Electrical Equipment Governor For Computer Case Fans Features: 1 Using nice materials, the quality is guaranteed 2 With switch, can be became off three The look of the product is exquisite four Simple and convenient wiring 5 Stable performance Specifications: 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 via switches and connectors, and might be expanded through power traces alone Loss of circuit board itself: lower than 20mA without fan PWM sign mode: 5V25KHZ PWM sign output range: 0%-100% Start function PWM adjustment range: 0%-60% Output interface model: 2510-4P dislocation, traditional CPU, chassis fan socket, pin spacing 2 Function Description: Pay attention to the nice and negative poles and the power delivery voltage After the ability delivery fan is connected, it may be used The potentiometer is turned off counterclockwise to the end, and the clockwise finish is the utmost output A separate small adjustable resistor (starting pace adjustment) at the board is used to adjust the speed of the just-open role If the speed change of the fan is opposite to the adjustment direction, it suggests that the fan is a reverse-sequence fan, and the (PF) surroundings point should be short-circuited with solder, and the power needs to be bring to an end before operation to bypass damage! The short-circuited PWM signal changes in the opposite route with the adjustment, and the reverse-sequence fan can realize ahead adjustment Precautions: This is a four-wire PWM fan speed controller It can solely management 12V four-wire fans that support PWM pace law For example, many 12V four-wire chassis or CPU fans can not management 2-3-wire followers Package Included: Module X1
