       Beta release of USB-based ACPI control...

                       Release of Software Devleopment Kit for the P2140 (4/11/07)


The CNX-P2140 185+Watt Dual-output Regulator with USB interface!

Includes revolutionary PSUmoniTM (Power Supply Monitor) application softare and USB connection between P2140 and your PC for real-time monitoring of voltage, current, power, and many software-controlled user settings!

The CarNetix CNX-P2140 is a new approach to providing power for car computer applications. With its built-in USB interface and the PSUmoni power supply monitor application software, you will have full visibility and control over your car computer system. You'll never again have to request a firmware change or program a PIC microprocessor since the P2140 firmware can be upgaded over the USB interface. The PSUmoni replaces your digital voltmeter (actually 3 of them) and provides a real-time readout of battery voltage, input current, input power, primary output voltage, current, power, and secondary output voltage, current, and power! Plus the P2140 gives you "soft jumpers" so that you can change any of the default timers (ie bootup lockout time, shutdown delay time, deadman timer), voltage settings (ie low battery threshold). With all of the nifty features of it predecessors (DLYON, Pulse Start, iSense, P5V compatibility, etc) the P2140 is truly a revolutionary new approach to DC-DC regulators!

The P2140 can operate in either +12V OR +24V systems, is autoranging, and requires no jumper changes to switch between +12V or +24V systems. The unit comes with chassis and variable speed fan, input/output pigtail power cables, and is backward compatible with all P1900 power cables, including MacPac and AOPac.

Upgrade your P1900 to include a 3RD regulated (+5V) output!

Can also be used as a stand-alone Point of Load (POL) regulator

Now Shipping!
Now you can add a 3rd regulated output to your P1900! Or you can power your USB devices from a stand alone Point of Load (POL) +5V regulator with up to 3 amps of current (15 watts of power)!

The P5V 5 volt regulator lets you power your Mac mini or Travla case (+18.5V), Screen (+12V), AND SOON ... +5V USB devices with a switched power source. The P5V can provide 3+ amps for power hungry USB devices like Audigy 2NX sound card, WiFi, and GPS devices. The P5V is a "bolt-on" upgrade to the P1900 that requires no soldering. It is also controlled by the DLYON control of the P1900 so that you can safely power down your USB devices when you ignition is off. As a stand alone POL regulator, simply connect the control line to the ignition input (for switched control) or to +12V contstant for "always on" operation.
