The three-phase AC fan uses a three-phase asynchronous motor inside, because the phase difference between any two phases of the three-phase power is 120°, so only the three-phase ...

The soft start function of the EC fan is usually implemented by the control circuit inside the fan. The soft start function is particularly useful for applications that require fre...

It should be noted that the life of a cooling fan is determined by a combination of factors, some of which may be interrelated. Therefore, when selecting, using and maintaining a f...

In addition, if you want to connect multiple fans in parallel to the same PWM interface, you may need appropriate circuit design to ensure the quality and stability of the PWM sign...

Taking this R4D500-RA03-01 as an example, you can see that there are a total of 9 outlet wires of the fan. In addition to the two ground wires for thermal overload protection the w...
