    Hi guys.

    I urgently need a power converter designed and built as inexpensively as possible. Future purchases guaranteed!!

    **CASH WAITING!!**

    I live in the UK, so if it could be designed (and built) here, it would be appreciated.

    Please see here for details of the voltages required.

    I can provide the 5v and 12v from a PC PSU, but need the 80v and 100v dual transformers. An all in one (5v, 12v, 80v & 100v) transformer would also be great.

    I'm concerned that if I was to design this myself, it would fry my very expensive DMD board or set fire to everything in near proximity!!

    Thanks in advance to every replier.

    Hi Packrat.

    We run at 240v in the UK.

    It appears the amp required are fairly low, Max of 2amps??

    Sorry, but I'm not too great with working with anything over 12v, so everything is worrying me a bit... :(

    Thanks again, but I'm afraid your last post is complete gobbledegook to me :(

    Unless it's simple enough for an 8 year old to understand, I'm knackered! LOL

    ...if you could simplify, I'd appreciate it. Thanks.

    The UK supply is one phase of a 3ph transformer and a grounded neutral.
    240v 1 phase.
    No 120v.
    BTW, all the voltages in the OP, are they at the DC level or AC?
    Max.

    Hi Max,

    Pins shown on the rear of the DMD board:

    Vsn
    Vrw
    key [blank pin]
    GND
    GND
    Vcc
    Vcm
    Vsp

    And how I presume they should be powered (according to the pdf)

    Vsn___________-110VDC
    Vrw___________+ 12VDC (- 98 VDC)
    key [blank pin]
    GND
    GND
    Vcc___________+5VDC
    Vcm
    Vsp___________+75VDC

    DC voltages obtained by a linear supply transformer are calculated as AC required = DC x .707v.
    Max.
