    How can I get 12V DC 2A FROM 220V AC Without transformer

    OR 12V DC 2A FROM 330V DC.

    You use a Switch Mode Power Supply. No other way around the DC input requirement.

    No, 330vdc to 12 vdc does not need transformer. Buck converter, buck-boost, SMPS, or even a simple resistor. Go for complexity: M-G!

    Now we do have some other problems to deal with however. I suspect that language barrier and answer shopping are the primary ones, although sheer ignorance is present, and it's the only problem this forum is meant to deal with. Please read the rules for posting on these forums, and if need be, go elsewhere on the web to discover what those words mean.

    Incidentally, you've already gotten your 12vdc, you just didn't know it.

    220 V AC TO 330DC
    330VDC TO 12V 2A
    I speak here about amps

    <Rude and inflammatory remarks removed -please be polite, its in the rules dc>

    We can't. Transformer-less power supplies are a forbidden topic.

    You are required to read and abide by the ToS.

    And this will get people to work with you to solve your problem how? o_O

    I have a circuit and it would be easy to build but given that attitude you can go 'eff' yourself instead.. :(

    Hello,

    No nead to be rude.
    Just read the User Agreement.
    See point 6.
    In there the transformerless powersupplies are NOT allowed.
