3.7 Electrical Specification
3.7.1 Supply Voltage
nominal Voltage:
12V +/- 5%
Wide Range input:
4.75 - 14V
5V_Stb:
5V DC +/- 5%
If a module is E1 rated and should be used in E1 temperature range the supply voltage must
be 12V +- 5%!
3.7.2 Power Supply Rise Time
» The input voltages shall rise from ≤10% of nominal to within the regulation ranges within 0.1ms to 20ms.
» There must be a smooth and continuous ramp of each DC input voltage from 10% to 90% of its final set-point
following the ATX specification
3.7.3 Supply Voltage Ripple
» Maximum 100 mV peak to peak 0 – 20 MHz
3.7.4 Power Consumption
The maximum Power Consumption of the different nanoETXexpress-SP modules is 4.9 - 6.2W (100% CPU load; 90°C
CPU temperature). Further details with measurements and TDP values of the single variants can be found in our
