Here are the specs directly from the website:

Automatic Safe PC Startup/Shutdown - Prevents data loss and corruption by properly starting and shutting down your CarPC.
Ultimate Flexibility - Every timer and many options related to the control of the PC, Inverter, Amps, etc. are user-adjustable. They are digitally selected and stored, will not drift like pots (which other SDCs use), are saved indefinatelly even during power loss. See the Configuration Manual for information relating to these settings.
Shutdown to Standby Support - Using this Option, your PC can shutdown to standby. This is useful because Shutdown/Startup to/from Standby is much faster than when using Hibernate.
Power-Protect™ - Monitors vehicle voltage levels and will prevent the PC from turning on or will shutdown the PC when the car battery is too low. Jumper settings allow the user to adjust or disable the voltage monitor.
Battery-Safe™ - Forces PC to shutdown if it hangs with the car off. Prevents you returning to a car with a dead battery due to your CarPC after a long day of work or play.
