The power supply can be operated in two types of modes: “Standard ATX Supply Mode” and “Battery Driven
Application Mode”. The input power voltage shall be 10 – 32V except for Battery Driven Application Mode
where the minimum power input voltage is 11.2V (down to 8V is allowed for maximum 1 minute). The power
input is protected against over-voltage transients, short circuits (>15A) and in Battery Driven Application Mode
the battery is protected against Deep Discharging.











Note 1: Peak Load (< 30 sec.) These values can be used as maximum load if active cooled.


In order to estimate if the DC-DC Power Supply is suitable for a specific project the following table can be
used.

The allowed load (without forced air) can be compared to the maximum load of the actual board. Maximum
load from LCD, HDD, PCI, AGP cards must be taken into consideration to make sure none of the outputs is
overloaded. The “green” numbers are the available power for these loads.


Unused available power on some of the power lines can to some extend be used on other power lines.
