5/ Power Considerations
5.1. CP3005-SA Voltage Ranges
The CP3005-SA has been designed for optimal power input and distribution. Still it is necessary to observe certain
criteria essential for application stability and reliability.
The system power supply must comply with the CompactPCI® specification.
The following table specifies the ranges for the input power voltage within which the board is functional.
Table 30: DC Operational Input Voltage Range
Input Supply
Absolute Range
Voltage
+3.3 V
3.2 V min. to 3.47 V max.
+5 V
4.85 V min. to 5.25 V max.
+5 V STDBY
4.85 V min. to 5.25 V max.
(optional)
Failure to comply with the instructions above may result in damage to the board or improper
operation.
5.2. Power Consumption of the CP3005-SA
The goal of this description is to provide a method to calculate the power consumption for the CP3005-SA baseboard
and for additional configurations. The processor and the memory dissipate the majority of the thermal power.
The power consumption measurements were carried out using the following testing parameters:
CP3005-SA installed in the system slot of a Kontron 2-slot backplane with a CPA250-4530G power supply
Two Ethernet ports (i210) connected in 1000Base-T mode
16 GB DDR3L SDRAM in dual-channel mode
One self-powered USB 2.0 hub (for mouse and keyboard)
The operating systems used were uEFI Shell and Windows® 8.1, 64-bit. All measurements were conducted at an
ambient temperature of 25 °C. The power consumption values indicated in the tables below can vary depending on
the ambient temperature.
The power consumption was measured using the following the processors:
Quad-core Intel® Core™ i7-5700EQ, 2.6 GHz, 6 MB L3 cache, GT2, Intel® HD Graphics 5600
Dual-core Intel® Core™ i5-4410E, 2.9 GHz, 3 MB L3 cache, GT2, Intel® HD Graphics 4600
Dual-core Intel® Core™ i3-4112E, 1.8 GHz, 3 MB L3 cache, GT2, Intel® HD Graphics 4600
The power consumption was measured using the following configurations:
Workload uEFI Shell: For this measurement the processor cores were active, the graphics controller was in idle
state (no application running).
Workload Idle: For this measurement all processor cores and the graphics controller were in idle state (no
application running).
Workload Typical: For this measurement all processor cores were operating at maximum workload and the
graphics controller was performing basic operation (e.g. dual-screen output configuration with no 3D graphics
application running). These values represent the power dissipation reached under realistic, OS-controlled
applications with the processor operating at maximum performance.
