The CNX-P2140 is a 185+ watt intelligent DC-DC power regulator designed to provide safe, reliable power to today's newest CarPCs......including the Mac mini classic, Intel Mac mini, Aopen Pandora, Xenarc, Cappuccino, and many other Pentium P4-based systems!

The P2140 proivdes two outputs. The primary output is jumper selectable for 12V, 18.5V, or 20V operation and can provide up to 11 amps (130 Watts) @ 12V, or 7.5 amps (150 watts) @ 20V. The secondary output is jumper selectable to provide either +12V to power your LCD screen  or +5V to power USB devices (such as the Audigy 2NX sound USB sound card) with up to 3 amps (15 Watts). The P2140 can accept battery input as low as 7.5 volts under full load during cranking while providing a well-regulated output so that your CarComputer does not crash, or as high as 34V in a +24V system).

The P2140 includes all of the sophisticated features of its predecessors (P1260, P1280, 1290, and P1900) such as Startup/Shutdown controller, Pulse Start (remotely start the P2140 with door locks, car alarm, or wireless device), and DelayON (prevents speaker "thump" during booting). The P2140 fully and safely supports "Standby" mode and will automatically shut itself down (by detecting excess current drain) if the CarComputer fails to properly go into Standby mode. If the Deadman Timer is enabled the P2140 will automatically shut itself down after a user selectable time (normally 72 hours) if the unit remains in Standby/Sleep too long. Mac mini users will appreciate the Deadman Timer since most Macs require Sleep mode instead of hibernate.

The P2140 is also designed to power larger systems that demand higher power, such as P4-based motherboards with full sized hard drives. The P2140 is fully compatible with the Travla C137 (90 watt and 120 models), the C138 (90 watt and 120 watt models) as well as the newer C158 (90 watt and 120 watt models) cases.!

In addition, the P2140 can be used with the Mac mini, Sumicom, Xenarc, IWill, and Cappucino models that require an 12v, 18.5v, or 20v power source.

Suggested retail price $149.99USD.

NOTE: *The CNX-P2140 is designed to operate with a “nominal” +12VDC or +24V input from a car battery or alternator. This input voltage can vary significantly from a low of +7.5VDC during engine cranking at cold temperatures, to +34VDC during jump starting or abnormal alternator “spikes”. The CNX-P2140 can operate under full load with an input voltage of less than +10.5VDC for the duration of engine cranking. It is NOT designed to take a continuous input voltage of less than +12VDC for an extended period of time while under heavy load. If the input voltage drops below the nominal low battery threshold (~+10.5VDC) for more than 10 seconds, the CNX-P2140 shutdown controller will go into “Forced Shutdown” mode which will turn off the CarPC after a 30 second delay. Since the user has control over low battery threshold, care must be taken to protect the P2140 from prolonged operation below +10.5V.
