Power System
The Power System includes the power supply, battery backup, and power
distribution for the iSTAR eX controller.
Figure 1.10: iSTAR eX Power Management System
Circuitry to manage the power distribution exists on the PMB, which is
mounted in the enclosure above the power supply and battery.
The PMB handles the low battery alarm and power fail alarm and controls
power to all peripheral modules and readers. A micro controller operates the
PMB and communicates with the iSTAR eX GCM via SPI.
Battery power will be supplied to all iSTAR eX circuit boards, peripherals,
and readers, enabling the system to be fully functional under battery power.
