專業Power supply - For DC and Stepper motors廠商

Current requirements for stepper motor controller power supplies: 

During operation, current consumption will vary depending upon how the controller is being used. Before shipment, our controllers are calibrated to the rated current of the motors they are to be used with.

If you do not specify a motor, the controllers will be calibrated to a factory default value. Due to Pulse Width Modulation (PWM) our controllers usually consume less current than the rated current of motors.

However, to avoid problems during worst case scenarios, we recommend selecting a power supply with a max current not less than the rated current of motors that will be connected to the controller.

In a case of multi-axis controllers, you will need to sum the current of all controllers connected to the power supply.
