Power Supply

Internal intelligent automotive power supply

  • PC automatically turns on and off with vehicle ignition
  • Supports the use of Standby as well as Shut Down and Hibernate (jumper selectable)
  • Normal input voltage: 7.5V to 30V
  • Peak input voltage: 7V to 36V
  • External voltage dropper recommended for 24V vehicles, available separately
  • Idle power consumption <3mA
  • High efficiency for extended battery life
  • PC will not reboot during engine cranking
  • Protection against transients and load dumps
  • Reverse polarity protection
  • Automatic shutdown with low battery (jumper configurable)
  • Automotive mini blade input fuse (externally accessible)
  • Regulated 12V & 5V switched accessory outputs for powering peripherals (up to 1A)
  • Remote output for turning on and off external devices, with 1 second "anti-thump" delay.  The behaviour of this output can be configured at order time
  • Configurable shut-down delay. The time between the ignition being turned off and the PC powering down can be changed using externally accessible jumpers
  • Configurable start-up and shut-down voltages to reflect the fact that battery levels and conditions vary between vehicles
  • Hard Power Off. In the event of a software crash during shut down the power will be cut to prevent draining of the vehicle battery
  • Post-boot lock-down. If the ignition is turned off having only just been turned on, a delay will be applied before issuing the shut down command, in order to allow the PC to fully boot before attempting to shut down
  • Ignition input behaviour is configurable. By default the PC will turn on when the ignition input is active, and remain on until the ignition input is no longer active, at which point the PC will shut down. Alternatively a push-button power switch can be installed on the chassis for non-ignition-switched behaviour
  • LED indicates PC status and assists with troubleshooting
  • Externally accessible jumper block for configuring power supply options
  • Reset switch in chassis (recessed)
  • 6-pin power input locking connector (break-out cable supplied)
  • 3-pin power output locking connector (break-out cable supplied)
  • Modified PSU firmware can be loaded for customers with special requirements - please contact us for more information
  • Factory Recovery Solution preinstalled for easy recovery to factory settings using F11 key at start-up
  • Preinstalled as standard if PC is ordered with OS license, optional otherwise
  • 2 years RTB
  • Extendable to 3 or 5 years if required. Click here for more information [Obviously a link will need to be created]
Estimated End of Life (EoL) Date

H2 2015

This is the earliest date at which we expect to stop producing new units of this PC model. However, the warranty for each PC will remain in place regardless of whether the EoL date has passed, and will continue for the duration of the original warranty period.

  • CE
  • E11 ("E-mark" - fully approved for use in vehicles, including all optional configurations above.  Approval number 10R-054687, certificate available upon request.)
Chassis Options

All models are available in one of three chassis:

  • ICPC-1 chassis - This is our most compact chassis, capable of being installed in a variety of locations within almost any vehicle.  While not supporting any PCI cards, the ICPC-1 chassis does allow an internal Mini PCI Express card to be used.
  • ICPC-3 chassis - The ICPC-3 chassis is only slightly larger than the ICPC-1 chassis, and offers additional RS-232 or SMA antenna ports, a low-profile PCI slot, and supports an externally accessible SIM card slot for the internal 3G / 4G module.
  • ICPC-4 chassis - Although the ICPC-4 chassis is our largest it is still very compact, and supports up to 2 full-size PCI slots*, plus an internal optical drive or removable hard drive module.
Chassis Features ICPC-1 ICPC-3 ICPC-4
Internal Mini PCIe card expansion Yes Yes Yes
PCI slot No 1 x low profile 2 x full-size*
Externally accessible SIM slot for internal 3G/4G   No              Yes Yes
2nd internal hard drive option No Yes Yes
Internal optical drive option No No Yes
Removable hard drive options No No Yes

*The ICPC-4 chassis has two physical PCI sized expansion slots.  However, the second slot has no internal connection to the PCI bus, and can only be used for back plates or daughter boards that do not require a connection to the PCI bus.
