CP6500-V
6.2 Power Consumption
The goal of this description is to provide a method to calculate the power consumption for the
CP6500-V baseboard and for additional configurations. The Celeron processor dissipates the
majority of the thermal power.
The power consumption tables below list the voltage and power specifications for the CP6500-
V board and the CP6500-V accessories. The values were measured using an 8-slot passive
CompactPCI backplane with two power supplies: one for the CPU, and the other for the hard
disk. The operating systems used were DOS and Windows
conducted at a temperature of 25°C. The measured values varied, because the power con-
sumption was dependent on processor activity.
6.2.1 Real Applications
The following tables indicate the power consumption using real applications.
The power consumption for the DOS was measured with power management not active.
