Choosing a power supply

[mrel]

Hello
I am hobby person not a technician person.
Need advice in choosing a variable bench DC power supply that is 0-30 dc voltage and 0-3amp.
I notice there is linear and switching type bench DC power supply.
Since i am hobby person i might use the power supply for all different kind of project,example i might use to test a DC motor or test a LED or what ever need a Dc voltage.
So question is which kind of bench dc power supply would i need Linear or switching power supply.
Thank for the help mrel

Either one would do. I would not choose based on switching / linear, but I expect the linear ones will be considerably less expensive. You probably will want one that can do either constant voltage or constant current, and has meters for each. I find a couple of these for about $80 on Amazon.com.
