Typical Mac mini power diagram.
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 ?
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.
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 =)
