Product Description

Recently arrived a batch of uncut fans, No need to re-wire it yourself, Modification is more convenient to use. Bulk high-power 12V70W brushless fan, Built-in drive circuit, Transport in bulk, so the appearance is somewhat bumpy and scratched, etc. If you mind the appearance, please do not buy, thank you! But the original line is still brought in the bag, You need to weld it yourself, For some short wires, it is best to re-weld the inner circuit board. A high-power brushless fan that is very suitable for modification, It needs 100hz frequency PWM speed regulation to run, It can be used with a signal board in our shop, The speed control signal board needs to be purchased separately. There are several specifications of this batch of fans, The size is basically the same, The fixed bracket part is different, Shipped randomly, the power is the same. This fan is a blower used in cars, It is used for heat dissipation on Japanese hybrid cars, Brushless fan of Japanese brand. The workmanship of the fan is of course very exquisite and precise, Very good materials, high-power brushless motor, The large impeller has a large air volume, Need 100HZ frequency signal PWM speed regulation, Adjustable in a wide range around 1.5W-70W, Correspondingly, after removing the impeller, the no-load motor speed is about 600 rpm-5300 rpm adjustable, A very good fan, Can DIY heat dissipation, blower, etc., This one is more violent than the other models in this store, and the power is about twice as high. The fan weighs approximately 650-700 grams. Note: Brushless DC motor, The positive and negative poles cannot be reversed, and the red wire is connected to the positive pole. The black wire is connected to the negative pole, the blue PWM speed control signal, 100khz input, pulse width speed regulation, signal voltage 5V. It is strictly forbidden to connect the wrong wire without brush, if it is connected incorrectly, it will burn the driver board. Need regulated power supply, voltage 8-15V can run, The power supply can be around 12V10A.
