Product selling point: 1. Can bring 8 fans at the same time, PWM fan speed regulation 2.4-wire fans or 3-wire fans with PWM speed control ports can be used in common use. Note that the fan interface sequence is commonly used. 3. The maximum power of a single fan is within 60W, and the total power is within 300W (note that the total power also depends on the power of the chassis power supply) 4. Multifunctional compatible to control multiple fans 5. The product is convenient and easy to operate Product Specifications: Working voltage: DC12V Quiescent current: 0.015A (standby state) PWM duty cycle: 0%-100% PWM frequency: 25khz Precautions: 1. Note that this model is PWM speed regulation, and the speed regulation frequency is about 25K. PWM is the speed control signal, P is the 12V positive pole, G is the 12V negative pole, do not make mistakes in the wiring sequence, it will damage 2. This type of governor requires the fan with its own PWM speed control function. Two-line fans are definitely not good, four-line fans are generally OK, and most of the three-line fans are not. In short, three-line or four-line fans need to have PWM speed control lines. It can be used, if you do not understand, you can contact the fan manufacturer to confirm. You can also test by yourself, short-circuit the yellow wire or blue wire of the fan and the negative (black wire) of the fan. If the fan can stop, it usually has a speed control function, and the corresponding line is the PWM speed control line.
