CarNetix CNX-P2140 185W Dual Output Intelligent DC-DC Regulator

$ 94.67

The CNX-P2140 is a 185 watt intelligent DC-DC power regulator designed to provide safe, reliable power to today's newest CarPCs. This includes but not limited to the Mac mini classic, Intel Mac mini, Aopen Pandora, Xenarc, Cappuccino, and many other Pentium P4-based systems!

The P2140 provides two outputs. The primary output is jumper selectable for 12V, 18.5V, or 20V operation and can provide up to 11.3 amps (135 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 13.5V or experimental purposes), 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.

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.

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.

Are you having trouble configuring your P2140 properly? Here are a few things to check:

First, the manual, which includes jumper settings and all kinds of helpful info. Pay special attention to the diagram and chart on page 11.

Second, if your P2140 has stopped working, please try reflashing to the latest firmware.

Third, try using the latest version of the PSUMoni software to interface with your P2140. You can adjust various settings and monitor the P2140 operation. Make sure you get the correct software for your operating system. Here's some instructions for installing it, and here is a place to download the software for XP, for Windows 7 (32 bit beta)***, and for Windows 7 (64 bit beta).***

*** This software is NOT yet fully functional for Windows 7 or 8.

For users having issues running PSUMoni software on Windows 7 systems, the Windows XP version of the software works when using Microsoft's Windows XP Mode which can be found at the following link: Windows XP Mode. http://www.microsoft.com/en-us/download/details.aspx?id=3702
