3.4 Electrical Specifications
3.4.1 Supply Voltage
» +4.75V to +18V on the VCC_12V pins and 4.75V to 5.25V on the
VCC_5V_SBY.
Power Supply Rise time specifications
» The input voltages shall raise from
≤10% of nominal to within the
regulation ranges within 0.1ms to 20ms.
» There shall be a smooth and continuous ramp with each DC input voltage from
10% to 90% of its final set-point, as required in the ATX
specification.
» The maximum ramp up rate shall be 1V/ms maximum in order to prevent any
excessive inrush current that could damage the module.
3.4.2 Power consumption Current (Windows XP SP3)
The testing performed to capture the supply current data used tested modules
mounted on a Kontron evaluation board with a mouse and keyboard connected.
The power consumption tests were executed in Windows 7 using a tool to stress
the CPU and memory at 100 % load. The power measurement values were captured
after 15 minutes of full load. All boards were equipped with a two (2) 2048-
MB DDR3-800 SDRAM. The modules were tested using the maximum CPU frequency.
For more detailed information, refer to the “Power Consumption” diagrams on
the EMD Customer section of the Kontron website.

Windows Desktop (idle) 12W
Maximum power configuration 18W
S3 with Wake-on-LAN disabled 0.6W
S5 with Wake-on-LAN disabled 0.4W
NOTE: It is difficult to test for all possible applications on the
market. There may be an application that draws more power from the CPU
than the values measured in the table above. Take this into
consideration if you are at the limit of the thermal specification, in
which case you should consider improving your thermal solution.
