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.
