Just need 12V, no molex or ATX
I've already :search:d, but I think my needs are a little different from most.
I need a good solid 12V for my SP-350, my Lilliput and an external hard disk. The SP-350 has an internal 2.5" drive and a DVD / CDR combo. The external drive is 3.5" and normally runs on a 12V AC/DC converter.
I woud like it to survive craking and run while the engine is off; I will turn the equipment on and off myself. I have already read about the Opus and the ITPS. But I don't need the full ATX power connector and I need it available under 13.5V.
This power regulator certainly looks like it would handle everything, and offers up to 500 watts as well! But the $100 price tag is a little daunting... I saw a surge suppressor at Radio Shack that had three cigratte lighter sockets and an LED. It looked like a gimmick to me and wouldn't handle under-voltage anyway. Radio Shack also had some small cigarett adapters that had selectors for various voltages (one of them being 12V). But I doubt such a thing would be able to drive all of my components.
Am I doing something wrong here? Should these devices be able to connect directly to BATT/ACC? I know it can sway down to 10V and when the engine's running it can climb to 14V. So I think a direct-connect isnt't a good choice. The Lilliput has a rather small in-line regulator shaped like an egg, but that thing probably couldn't handle the load of all the other devices either could it?
I don't have the skills to follow one of the well-developed schematics and build my own, so I'm looking for a pre-fab option here. Any thoughts are very welcome: you guys seem to be experts on this stuff.
