    ITPS features when using an Invertor

    Hi, i've decided to power my carPC off an invertor as DC-DC is expensive and pretty rare in the UK. Just wondering how i could control hibernate via the ignition ACC cable. Any other ideas on replacing what the ITPS would have done when using an invertor?

    Regards

    One thing you could do is to buy an ITPS (only $39) and have it drive a relay that turns on and off your inverter.

    The ITPS will turn the computer on and off with the ignition using the computers power button, and then power the inverter on and off at the right times.

    Cheers

    There are lots of limitations with the ITPS, search for ITPS and you will see lots of debate/experiences. I use one, and I am quite happy with it.

    The ITPS will turn the computer on and off with the ignition using the computers power button, and then power the inverter on and off at the right times.
    The problem with this is that the ITPS will send a signal to the computer to power on/off and also drive the relay to the inverter. When the computer recieves the signal to power on - the inverter has not started yet - relay adds delay then the delay for the inverter to start up. Is there a way to get around this? Possibly delaying the signal to the computer?

    Set your computer's BIOS to turn on when power is restored.

    Crap - the bios thing did not work. Still same problem. How can you delay the poweron signal that goes to the motherboard by a slight amount - eg. 0.5 sec or even less???
