    ITPS confusion question

    I was all ready to buy my ITPS to allow my computer to enter/exit hibernation with the ignition then i read in a post that the ITPS can only handle 60watts? I'm running a EPIA 800 with full size hard drive and dvd burner and while wattage isnt registering over 150 watts (enough to start the fan on my inverter), i KNOW i've gotta be running more than 60. I was told before that the ITPS would work for me but i'm confused now. Help me out please

    If you are using the ITPS for regulating voltage to 12 volts, then yes, it maxes out at 60 watts. If you don't need to use the 12 volts DC regulating part of it, you can solder a bump to bypass that.

    I got the PW-80 PS, which is regulated. If/when I get an ITPS I can just bypass the regulation, but 60 watts would be enough for my setup.

    Ok i understand bypassing the regulator, but soldering a bump... does that mean soldering to permanently disable the circuit? I'm not up on the lingo lol

    Yes, from looks of it, you just solder together to wire sticking out on one side of the board together. There is no documentation on the site that shows it, it references a figure 1.1 but there is not a figure 1.1 anyplace that i can see.

    Hold up.. I got a question.. Does the PW-70A regulate power as well? If this is true then the ITPS can just be used as a startup / shutdown controller but if it doesn't then the ITPS needs to be also used to regulate power.

    Sonic,

    There is a keyword in your post, inverter. If this is a dc-ac converter then the best way to use the itps in my opinion would be to use it to invoke a relay to your inverter.

    I can give you more details if you should need them.

    I think only the PW-80 is also a regulator. That is why I got it over the other powersupplies. I have a 19v 3.6A laptop brick that I use in the house and when I am working on it, and I just plug it into a cigarette lighter adapter in the car (it isn't even close to being done, I am not in much of a rush, learning as I go along but not learning the expensive route).

    the PW120M would have fit way better, but then I would have needed an external regulator. I wanted to fit everything in a 7x7x2 box, I got it all in a 7x7x2 1/4 box. I am looking for a way to make it 1/4 shorter.

    Its a 400 watt modified sine wave inverter. I currently have it running straight to the battery. Its on all the time and i control power to the computer using a switch on my keyboard. The current setup really isnt that bad. I have no interference and i only have to wait ~30 secs for the comp to load n start playing, i'm just looking allow the computer to automatically start with i remote start my car. My inverter survives crank fine as well. Please explain in more detail what ur referring to.
