Carnetix CNX-P1900 Dual Output 140 watt Regulator

I have an old CNX-1900 140W Dual Power I bought back in 2005 so It's probably version 1.0

And now I have a fit-pc2 computer that accepts input of 8-15V and a 7" LCD that wants 12V.

is possible to power these two with the CNX-1900 ?

Hi!

Just got my install ready and first time been playing with it while driving.

I have a odd problem with my system. It runs smoothly when switching the ingnition on. But if i start the engine and let it play about a 1-5 minutes whole system gets cut off from power. Screen blanks and PC goes powerless. I believe it is not shutting down or anything. Just cuts them off... Starts again if the ign.key is turned again. Any ideas? Wrong jumper setting?

Ill inspect it more tomorrow.

<update>
Drove around for awhile with multimeter attached to Carnetix main power input (+ and ground). The voltage was quite low around 11 volts... (my alternator is not very good) and when the voltage dropped to near 10 V the Carnetix shut down the PC. My screen was away from its bezel and i could see the Carnetix and usb hub. From there i could se that PC was shut down fast but Carnetix red led was blinking and USB hub light was off short after that, so i believe it (Carnetix) did what is should have done when voltage drops =)

So now i need to bring bigger + wire from battery, insert a fuse and check my alternator connections to juice up the power supply.

Yep, i pulled a stronger + cable and it solved the problem. Yet need to upgrade my alternator but i keep the battery to charger over nights to have full batt avary day =)

I have a P1900 from an old Mac Mini install and was wondering whether it can be used to power a 19V 2.1A DC netbook. It's well within the limits of power consumption but I haven't been able to find any examples of this combination/setup so I'm wary of trying it out just yet.

I don't see a problem with the 1900 powering a 19v laptop. i think the carnetix p-1900 puts out almost 10amp peak. You just need to get the right plug-end for your laptop. SNO

I am powering a full size HP laptop with no issues. You should be good to go. Just remember if you add a lot of USB devices without using separately powered hubs, all of those devices power requirements must be factored in to the draw on the 1900.
