Hi all,

I don't know whether this is the right category to post this question. I need to build a panel which is controlling stepper motors and has some controllers and sensors. It must be powered using an SMPS which will give you a 24V DC output. The confusion is how to select SMPS(Specification) for this kind of system.
If the stepper motor is rated for 4A and if we are using a chopper driver to drive it, I think motor won't need a constant 4A in order to operate. So it there is 2 4A motors and one controller which is rated for1.5A at 24V. How to select SMPSwith correct current output?.
