Buying Tips:
For this listing, we provide three different options for buyers. The model A includes single brushless fan; the model B includes brushless fan and adapter cable; the model C includes brushess fan and adapter cable and PWM speed controller. Please buyers purchase according to your needs. Thank you.
Note: This batch of brushless fans is in bulk, there are slight flaws in the appearance.
If you mind it, please purchase with caution.Thanks.
Model A: DC brushless fan
DC brushless fan is in stock. The fan blades rotate together with the outer frame. The fan motor direction is CCW. The wind blows downward, that is blow air in the direction of the motor.
The shell of the motor is made of aluminum alloy, the base is a metal base, the motor is exquisite in workmanship and high-end materials. The applicable voltage of the motor is DC12V and the current is 0.45A. It supports high-speed operation only by connecting positive and negative poles, and also supports input PWM signal and duty cycle speed regulation.
The lead wire of this fan is six feet, counting from the right side facing the copper wire. The lead wire is defined as follows:
Pin 1: +12V
Pin 2: +12V
Pin 3: PWM (frequency 5000HZ, duty cycle adjustment is speed adjustment)
Pin 4: GND (common GND for power supply and PWM)
Pin 5: I don't know the purpose, it is estimated to be FG, it is OK to suspend it.
Pin 6: GND (common GND for power supply and PWM)
The first leg and the second leg of this fan are connected to the positive pole of the power supply, and the fourth leg and the sixth leg are connected to GND. If only the positive and negative poles are connected, the fan will run at the highest speed. If you need to use PWM signal speed regulation, then input PWM signal on the third foot, and the negative pole of PWM signal should also be connected to GND in parallel. Adjusting duty cycle is speed regulation.
