Pico PSU overloading problem.

  1. May 4, 2008 #1
    hi all,
    we have problem powering up the Pico PSU 120 power supply, its been powered up by a 5A Regulated DC supply, instead of an adapter. No load is connected. at this point it is overloading. consuming more than 5A. we have 2 of the units in house and both are having same problem. does anyone has any experience using it?
    BTW we are trying to contact the manufacturers on this.
    Sorry i was not allowed to post the Url's.

    and in one of the FAQ, it is also answered that the initial current consumption may exceed 5A because of the buck boost topology incorporated.

    Send me a PM with the links, and I'll post them for you. Is this power supply an off-line supply, which takes AC Mains input, and gives some DC output? What are the specifications? You say you power them up with no load, but many power supplies have a minimum output current requirement to stay stable and in regulation.

    this is just a replacement for SMPS, where power requirements are not a high as it would be in standard Computer system. it is normally used with mini-itx motherboards.
    it takes 12VDC as i/p.
    Berkeman, i have posted the links to you as a PM.
    Thanks
