1 ﹞ two lines are generally control the output voltage magnitude can be controlled "Cooling Fan Manufacturer" speed fan speed 1.2 lines divided into client and unprovoked (bare) two kinds of wiring, terminal model specifications, wire polarity direction and gauge by user-specified. Generally lead wire in two colors, red and black; red wire to the positive supply voltage, the black wire to the negative power supply voltage.
2 ﹞ FG signal to control the size of the output voltage can be controlled "Cooling Fan Manufacturer" speed, the third FG signal line provides a square wave frequency signal to the device to detect its fan speed in real 2.1 line FG signal output "Cooling Fan Manufacturer" points and there is no reason to end (bare) two wiring terminal model specifications, wire, and wire gauge polarity direction specified by the user. Generally lead wire in three colors, red, black and white (or yellow), red line then the power of positive voltage, then the power of the color black line voltage, while the third signal line leads FG, FG signal line color routine for white, yellow two kinds; (wiring diagram below).
