CP3010-SA
4 Power Considerations
4.1 CP3010-SA Voltage Ranges
The CP3010-SA has been designed for optimal power input and distribution. Still it is necessary to ob-
serve 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.
Note:
Failure to comply with the instructions above may result in damage to the board or improp-
er operation.
4.2 Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the CP3010-
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:
»
CP3010-SA installed in the system slot
»
Ethernet ports not connected
»
4 GB DDR3 SDRAM in dual-channel mode
»
+3.3V and +5V supply voltage
»
2.5 m/s airflow
The operating systems used were uEFI Shell and Windows® 8.1, 64-bit. All measurements were con-
ducted at an ambient temperature of 25 °C. The power consumption values indicated in the tables be-
low can vary depending on the ambient temperature. This can result in deviations of the power
consumption values of up to 15%.
The power consumption was measured using the following the processors:
»
Quad-core Intel® Atom™ E3845, 1.91 GHz, 2 MB L2 cache
»
Dual-core Intel® Atom™ E3827, 1.75 GHz, 1 MB L2 cache
