Just got it in the mail today, ordered from mp3car.com, realized I'm going to need more power, so I need the CNX-P1240. Paid 100 shipped, willing to let it go for $95 shipped. Brand new, never used, never connected. I can show the receipt to anyone who is interested.
Specs from mp3car:
The CNX-P1290 is a 90 watt intelligent DC-DC power regulator designed to provide safe, reliable power to today's newest CarPCs......including Travla & Morex cases, as well as many of the Sumicom and Xenarc PC systems.
The P1290 proivdes two outputs. The primary output is +12V and can provide up to 6.3 amps (75 Watts). The secondary output is +5V to power USB devices (such as the Audigy 2NX sound USB sound card) with up to 3 amps (15 Watts). The P1290 can accept battery input as low as 7 volts under full load (90 watts) during cranking while providing a well-regulated output so that your CarPC does not crash.
The P1290 now includes an internal relay to control the ACPI interface of the Sumicom and Xenarc PCs. No more soldering an external relay between the P1290 and the PC!
The P1290 includes all of the sophisticated features of its predecessors (P1260 and P1280) such as Startup/Shutdown controller, Pulse Start (remotely start the P1290 with door locks, car alarm, or wireless device), and DelayON (prevents speaker "thump" during booting). The P1290 fully and safely supports "Standby" mode and will automatically shut itself down (by detecting excess current drain) if the CarPC fails to properly go into Standby mode.
90 Watt Dual Output Regulator Main output of +12V @ 6.3 Amps Secondary output of +5V @ 3 Amps Survives Engine Cranking under full load over entire temperature range Includes sophisticated Startup/Shutdown Controller Compatible with many of the Sumicom and Xenarc PC Systems. INCLUDES INTERNAL ACPI RELAY FOR SUMICOM AND XENARC PCs Includes sturdy aluminum chassis with variable speed fan suitable for car environment Field upgradable flash microprocessor Low battery monitor prevents drained battery, even during Standy/Sleep "Anti Thump" delayed remote control for audio amplifiers Remote "Pulse Start" from wireless device or car alarm/remote start system Over current protection on both outputs with graceful forced shutdown of main output Powers both your CarPC AND your screen or USB devices Compatible with many of the Travla & Morex cases Full, safe support for Windows Standby mode including auto shutdown if PC fails to shutdown Over voltage surge suppression on battery input for protection of harsh automotive environment User replaceable fuse on battery input to protect your car from internal short circuits Very compact design measuring just 4.6" x 3.25" x 1.75" (L x W x H) or 117mm x 83mm x 45mm.
