Figure 7-11
on page 7-40
presents a block diagram of the BATTipx and the power
circuitry that enables the IPx 500M and IPx 500X cages.
The PS500 AC is normally fed by AC power input from which it produces the DC
outputs required for normal card operation. It also produces charging voltage to the
battery pack. The PS500 AC and the battery pack are connected via two wires.
If a power fail occurs, the battery pack feeds the PS500 AC, allowing it to produce the
DC outputs.
DC Output Power
The PABX/PS terminal block supplies power to the Coral IPx 500 cage only in
the event of a power failure.
The LTU/CSU terminal block supplies the LTU or CSU when power is
functional and when there is a power failure.
Normal Operation - When an AC Power Source is Available
The AC input passes through the PS500 AC input into the AC to DC converter circuit.
The converter circuit produces an output of 54VDC. The 54VDC is fed into the battery
charger circuit.
The current is reduced to charging current of 300-700mA. The output passes via the
PS500 AC internal mounted battery fuse to charge the four 12V batteries. As long as
the AC input is operational, the batteries are charged.
During normal operation, the green
Power
indicator on the front panel of the
PS500 AC is illuminated to indicate that the output power voltages are being
produced. It means that all the circuitry of the PS500 AC is working properly.
Battery Pack Operation in the Event of a Power Failure
The DC input to the PS500 AC consists of battery wires, a 10A battery fuse, and a
charge current limit.
If the AC power is discontinued, the PS500 AC automatically operates from the
battery pack. The power provided by the battery pack is fed into the current limit
circuit as well as the DC/DC converter, thus replacing the DC power usually provided
from the AC/DC circuit.
