    ANY ELECTRONICS EXPERTS ON HUKD??

    i have some eq requiring 7V @ 300mA and have a universal Regulated adapter that can provide 7V @ max 1900mA.
    If i use this adpter does the "regulated" mean the adapter will automatically configure to provide the required ampage of 300mA?

    Please advise!!

    it doesn't work that way.
    the ampage is its rating in other words it can supply 7V at upto 1900mA

    if you use less current then it doesn't matter because its regulated. if it wasn't regulated then the voltage could increase/decrease depending on current

    So can i use this adapter with my eq? i.e. the eq will only draw 300mA?

    Yes, it's safe...

    yes perfectly fine

    thanks guys. btw marzbarz ur avatar rocks!!!
    don't condone the smoking though:p

    yep its perfectly safe.

    Easiest way to look at it is as follows...

    Voltage is an essential requirement that needs to be matched on a PSU. Amperage can either be matched or rated higher (never lower) on a PSU.

    the most important thing to look for (other than the correct voltage) is to ensure its regulated. an unregulated power supply will allow the voltage to creep up if the current is low and this will fry sensitive electronics.

    better get out of this thread, I forgot my anorak !!!

    Best to make sure the polarity of the plug matches you equipment.

    lol
    best remove mine and put it back in the wardrobe.

    but remember this. when you break something you always look for the anorak ;-)
