  • What hapens when you draw too much from opus 90w?

    Ok here the whole story did too many thigns at once not sure which could of done it.

    Ok first off I ran a powered usb hub to front of car to power gps mouse and lcd and rf remote thing. Anyway I used to have it on its ac plug into a inverter but was just temp fix. So this weekend I ran a 5v and ground from opus drive output and hooked it into hub as hub rates 5v @ 2.5A.

    Second thing Id id was hard wired my rader detector and lcd screen and used the same ground that the opus uses.

    So this morning I come out to start my car and put some movies on the drive and it won't boot. I check the 10A fuse on Opus and its blown. So I steal one from rear wipers on my cars fuses and not it will do its I'm here normal idle blink. Then soon as I plug in the atx power for pc it dies no blinking at all. so I get out a ac one and plug it into a wall and it powers board up fine. So I go back and leave atx off opus it idle blinks fine then plug in atx and it dies again. No idea whats goign on thinking I killed the opus tho but anyone know what thing did it and if it really is blown?

    Thanks,

    Disconnect some peripherals so not as much power is drawn, replace fuse, try again.

    I pulled too much power from my opus 90, and all it did was refuse to start up. To think of it, it never blew a fuse with me, so you might have another problem. If the first step doesn't work, start looking for possible shorts.

        well have it limping now off the 300w inverter and 350w ps I relaly liked the small form factor of dc-dc tho will see if tech at work tuesday has any ideas he can usually fix about anythign or maybe make me a $20 opus 300w dc-dc any idea you guys have tho lemme know I find it odd that it will still light the led and know its state but just can't power up makes me think I cooked its dc-dc ps

              opus sent me a new one, it only blew when my battery voltage was low, it operated fine under 12v+

                It BLEW because your voltage was low? That doesn't make any sense.

                  well if you think about it it does really, lower voltage means it has to pull more current to supply the computer with the same amount of power, this increased current obviously one of the components couldnt deal with and went up in smoke, the opus circuitry should have prevented this, but it didnt, twice

                    Yeah it makes sense ...... as voltage decreases the amperage deeded to operate will increase. Thats what fried Opus. A moment of silence for poor Opie

                        This is also one of the reasons I think that in Australia they are lowering the voltage from 240v to 230v, this way products won't last as long and people spend more. Although some new products are being made with this in consideration.

                        Just an idea.

                          its also the same reason why they haven't come out with the perpetual motion engine for my car so I have to keep buying gas.

                            That's right it's all a big conspiracy. One thing I don't get is if they are controlling our minds with flu shots to spend more (that's why they are given during winter, just before christmas) then what happens in Australia, as our winter is in June.

                            They didn't think of that one did they.

                            The TRUTH is out there....
