    Dear DCX3 Owner,

    We have found a series problem with DCX3 DC-DC power supply modules.
    if you have not applied power to the DCX3 DC-DC yet, please DO NOT use it
    until you have read this email and have taken the necessary steps to correct
    the problem.

    DCX3 has a problem when the initial power is applied to it. The noise
    generated at the instant the power is applied to the input terminals causes
    unpredictable behavior in the power supply controller output. This behavior
    sometimes damages the output stage of the power Supply. Depending on the nature
    of the device failure the input fuse may or may not open or the input may be
    shorted to the output in this case it will cause damage to the loads.

    If your DCX3 is already powered up and running then there is no concern at
    the moment. But, When you disconnect the input main power (battery) then
    the above modification MUST BE DONE BEFORE YOU REAPPLY
    THE MAIN INPUT POWER to the DCX3 unit.

    The following modification will solve the above problem. Please take action
    immediately to solve the problem. If you are not able to do the following
    modification and/or if your unit is already damaged then please send it to:

    RMA- DCX3
    OPUS solutions, Inc.,
    6 Reef,
    Laguna Niguel, CA 92677.

    Please include your return address, telephone number, the invoice # and date
    with a heading on the note "RMA-DCX3". If your unit is already damaged please
    indicate with a note "Damaged" on the bottom of the note.

    We will repair the unit/s and/or modify the unit and return it back to you.

    MODIFICATION PROCEDURE
    Refer to the attached drawing for reference/ detail

    Please observe STATIC PRECAUTION when performing the following modification
    and during installation. Ground and discharge the body static charge before
    performing the following modification.

    The modification is simple if you or some one you know with good soldering
    skill. You will also need a tweezer for handling 0805 resistor chip.
    You will need a 15K or 22K ohm 5% - resistor. If you need it we can send it
    to you.

    The problem is solved by installing / soldering a 22K ohm 5% -0805 size
    resistor between the TP2 pad (Round pad) and top pad of D15 (Square pad).

    These components are located just above and just right of the printing "
    PATENT PENDING " on the DCX3 Printed circuit module.

    Please reply the email with the following questions answered.

    My power supply is: Working, Defective or don't know

    If defective, please explain the nature of the failure,
    How and when you noticed the problem.

    Modification will be done by : OPUS or me

    If you are performing the
    modification then do you want
    us to send the resistor: Yes/NO

    If Yes, Please provide your mailing address and telephone #.

    (Just to clarify)
    Don't you mean a +12V reading on the +3.3V rail?

    I'm curious to hear how many have this problem and what Opus is going to do about it.

    My 90W opus arrived around the first week of August, 2003, so I guess I ordered mid/late July.

    It ran fine a couple of times, then I unplugged it. When I plugged it back in, the fuse blew.

    Later, I plugged the power supply in, but attached no load and measured the
    3.3V to be 12V!!! No wonder it fried the MB. My Epia 800 is now a door stop.

    Others on the board with the problem that I know of off the top of my head include adamis, and yellena...

    Argg what a crappy design, thanks god i dont need OPUS. A good PSU design should protect the MB whatever happen.

    I heard you guys pay so much for this, blown PSU and MB :S

    my opus 150 watt works just fine. I've had it for maybe 4-5 months so far. BUT I noticed when I shut off my commputer. I can't turn the computer back on, Id have to turn the ignition off then on...Then turn the comp back on. No biggie, just annoying.
    Mine needs to be updated.

    wire a switch in between the ignition and the psu. So next time you can flip it off and then on. this should work
