oh.. i see.
then, I better use a transformer to convert AC power into DC power and connect some type of bridge rectifier right after the transformer.
My intension is to make a circuit of bridge rectifier by myself so I figured this circuit would be suitable http://www.eidusa.com/Electronics_Kits_diode_bridge.htm
But, it doesn't show any voltage level...
Most of my applicatios would be controlling small DC items such as tiny solenoids, motors etc.. so those items will be needing between 12VDC ~24VDC.
I can understand that i must use a transformer. But, unfortunately I don't have any knowledge how to use DC power(from transformer) to make it at certain voltage level such as 12V, 24V.
Currently, I am trying to control a stepper motor but I think I need to do something to power it before controlling it.
Its specification is like this.
*Voltage *Current *Holding torque *resistance *Inductance
24V 2A 16kgf 2.5ohm 4.9mh
In this case, the current it would draw is 9.6 as I = V/R.
Could you please advise me how to approach to this specific case?
