Streamlight StreamLight Personal Computer CPMC-1553R Manuel D’Utilisation

The CPMC-1553R uses 3.3 volts and 5 volts power.  VIO, +12 volts, and –12 volts are not used.  The 3.3
volt supply powers the PCI interface and the 5 volt supply powers each of the ACEs.  Typical current draw
is at 25

°

C at the “Typical” power voltages.  The “Maximum” current draw is over the worse case condition

of voltage and temperature.  Table 12 shows the power specifications for the board.  Note that I

 is for

each ACE installed.  With two ACE chips installed double I
