Power Supplies

Once you have your machine and your displays a long with all of the other gadgets that you want for your carputer you will need some way to power it.

It all comes down to two options:

  • A power inverter
  • A DC-DC power supply

Your car's battery puts off 12 volts of DC electricity. Computers natively utilize DC power as well. Because most computers are used in the home or office, they must be able to convert the electricity that comes out of the wall (which is AC curent) to DC current. This is where you will need a power inverter to convert the DC current from the car to AC current that the computers power supply can utilize. Then the computer power supply converts the AC power back into DC power so that the computer components can utilize it. In short, if you choose to use a standard computer without a CarPC specific power supply you will need a DC-AC inverter.

Your other option is to use a DC-DC power supply (such as a M2-ATX) which will allow you to connect the 12 volt DC power from your car to your computer. Most DC-DC power supplies have other features such as an ignition switch which will turn your computer on when your car is started and will send a signal to go through a soft shut-down process or put the computer into stand-by or hibernation. Most of these DC-DC power supplies also incorporate an amplifier turn-on signal which is timed to not send a turn-on signal until the CarPC has alredy started the boot-up process. This feature is usually configured to prevent amplifier turn-on thump which can not only be very annoying, but can also damage your speakers.

Micro Shutdown Controller
Micro Shutdown Controller
Our Price: $41.99 In Stock!

The uSDC or Micro-Shut-Down-Controller is an electronically
controlled automotive power switching device. It is primarily designed
for the purpose of starting up or shutting down a personal computer
used in a motor vehicle. It interfaces with a computer motherboard’s
power switch header that would normally connect to the push-button
switch on the front of a personal computer case. The uSDC includes a
high current relay that will cut off or apply all power to the power
supply of the personal computer to prevent any substantial current draw
when the computer is not in use. The uSDC also provides a timing
mechanism that is user selectable allowing the computer to remain “on”
for an amount of time after the ignition has been turned off. The uSDC
allows the user to mount the personal computer in remote locations
(such as a trunk) and provides hands off method automating the startup
and shutdown sequence while constantly monitoring the environmental
conditions.

 
 

Note: This is for a PCB board only. User will have to provide
adequate casing, blade style automobile connectors, and wiring to
properly use this product.

CNX-P5V 15 Watt +5V Regulator
Carnetix CNX-P5V 15 Watt +5V Regulator
Out of stock until early June
Our Price: $24.95 (Out of Stock)

Upgrade your P1900 to include a 3RD regulated (+5V) output OR it can also be used as a stand-alone +5V/15 Watt Point Of Load (POL) supply

Now you can add a 3rd regulated output to your P1900! The P5V 5 volt regulator lets you power your Mac mini or Travla case (+18.5V), Screen (+12V), AND NOW... +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 that requires no soldering when installed in the P1900. 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.

The P5V is a small (.86" x 1.5", 22cm x 39cm) board that mounts inside the P1900 to take advantage of the heat dissipation capabilites of the chassis and fan. The P5V runs quiet and cool while easily providing over 3 amps of current: plenty for both a powered USB hub plus USB devices AND a USB soundcard. The P5V contains a thermal shutdown feature which automatically activates if you attempt to draw too much current.

The P5V installs easily into the P1900 using only a phillips screwdriver. The output wires may be attached to your existing hub power cable by simply connecting two wires.

The P5V can also be used as a stand-alone Point Of Load (POL) regulator for +5V devices. For applications that require more than about 1 amp, a small heatsink will be required (16 degC/Watt). Alternatively, the P5V could be attached to an existing metal chassis (the P5V mounting tab is at ground potential) instead of using a dedicated heatsink.

Morex 60 & 80 Watt Power Supplies! BLOW OUT!
Our Price: $19.99

12V input 60W or 80W power supplies. These units do not have an internal voltage regulator or a startup/shutdown controller (i.e. you shouldn't connect them straight to an automotive battery). These power supplies need regulated 12V input, so you could use them in conjunction with a voltage regulator (like the CarNetix P2140), or an AC/DC power brick.

When submitting the order please specify in the comments section whether you need a 60W unit or a 80W unit.
