A stepper driver should be equipped with a suitable power supply to play its performance to the extreme, and how should the power supply be selected?  
   1. First of all, the voltage ratio of the power supply is about 15%-55% of the maximum voltage, and the percentage ke.kt, so the voltage immediately drops, but they are not the same
    2. The current value of the stepper driver must be sufficient to transmit the required energy
    3. At this point, it is important to remember that the output voltage value of the stepper driver and the supply voltage are not the same, so the input current and the input current of the stepper driver are also different.
    4. If we want to provide the appropriate power supply current, we must calculate an increase of 6% on the basis of the original demand. We can calculate the current we need by calculating i=p/u according to the following company.
    5, if we only from the point of view of the stepper motor, the greater the power of the power supply, the better, but our requirements in daily life are not the same, our requirements are the lower the better that we often want to save costs.
    6, but once the power is too low, it is easy to lead to the stepper motor in the need for power may be insufficient and lost step phenomenon, in there is easy to damage the stepper driver and switching power supply, this does not have a unified standard everyone according to the manufacturer's requirements and product configuration to flexibly use.
