    Hello,

    I need a 30Vdc supply to power a lamp.

    I have two separate 15Vdc supplies. The 15Vdc is from a transformed & rectified 230V ac mains supply. That is I have two separate power supplies.

    Is it possible to connect these 2 separate rectified 15V dc supplies and if so how do I do it??

    Is it possible to do like attached?

    Thanks in advance,

    WM

    It will work. Connect exactly as you have it in your diagram. Two similar sized power supplies, and are enough VA for the load when combined.
