4.1.1. Power input
The PCM/PDM provides a galvanic insulation between the power source and the AWC 500 system.
The PCM/PDM is equipped with a switch mode power supply, which generates supply voltage for the
control part of the PCM and for supply voltages to the other modules.
The PCM/PDM has a build-in 20 ms (minimum) power blackout protection. This feature assures that if
the power suddenly drops to below the minimum threshold the complete AWC 500 system; including
all IO module within the rack; will continue to operate as normal. If power returns within this 50 ms
period the AWC 500 system will continue un-interrupted. If power continues to be absent after this
blackout protection period the AWC 500 will enter its Safe Shutdown Cycle in which it will assure that
all data addressed to the non-volatile memory is securely written.
The PDM offers two redundant and prioritized power inputs. The PDM will always source its power
from the primary input (`Pri') until this drop below its operating threshold in which case the PDM;
without interruption; will switch to the secondary input (`Sec').
The total power consumption of the PCM/PDM depends on the configuration in the rack, as the
modules have different power consumption.
