ipx Battery Pack for AC Powered System
7
When the battery voltage drops below 44VDC, an alarm signal is generated, giving
the operator the time needed to perform shutdown procedures.
The power supply automatically restarts when the AC power returns. The battery pack
is recharged as soon as the AC/DC converter provides over 50VDC.
Disconnecting the AC Power Cord from the PS500 AC
Disconnecting the AC power cord from the AC power mains will not cause call
processing and Coral system operations to discontinue. The battery pack takes over
and provides the DC inputs necessary for the DC/DC converter circuitry. All output
voltages will remain active. The only way to disable the output voltages is by turning
OFF the PS500 AC power switch.
Turning the BATTipx Power Switch OFF
During normal PABX operation:
Battery charging will stop
LTU/CSU power is supplied by the PS500 AC power supply (54VDC/700A
max.)
During AC power failure:
The Coral IPx 500 system shuts down
LTU/CSU power is discontinued
Turning the PS500 AC Power Switch OFF
Turning the power switch off allows you to shut down all power to the Coral IPx 500
system as well as to stop charging the batteries. It is used for maintenance purposes.
The batteries will be discharged by the LTU/CSU if connected. To stop the battery
from discharging, turn the BATTipx switch OFF.
Monitoring Circuitry
Monitoring circuitry in the PS500 AC verifies that each voltage output is within
specification. If any voltage deviates from specification, the monitoring circuitry
produces an alarm signal to the Coral system processor, causing the red
Alarm
indicator to illuminate. Note that the green
Power
indicator of a PS500 AC remains
illuminated at the same time as the red alarm indicator.
