    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

    be aware that the 0-30V and 0-3A is misleading sometimes.. You also need to look at wattage.. For example some say 0-30V,0-3A but then 30W.. So you can do 30V @ only 1A or 10V @ 3Amps
