Note:
Indicated consumption currents do not include consumption of expansion
modules and peripheral devices.
Peak consumption current is an estimated value of maximum possible
consumption current within a pulse.
Max consumption current (TDP) is a measured value of consumption
current during maximum loading of the CPU and memory using testing
software utilities at ambient tempe25
°
C.
Input power connections should provide minimum power loss. Avoid using long input lines, low
carrying capacity cables, high resistance connections.
6.3
Power Consumption of Expansion Modules (Unipolar Power
Supply)
Maximum total current consumption of StackPC (PC/104 PCI) expansion modules and USB, PS/2,
and SATADOM devices should not exceed the values shown in the table below.
When powered from a unipolar power source, it is allowed to connect additional load (+3.3 V and
+5 V) to XP5 connector considering the total consumption current limitations.
When powered from a unipolar power source, +12 V and -12 V voltages are not supplied to
StackPC (PC/104 PCI) expansion modules.
