AC 220V/DC 5V & 24V PS Card is used to convert the field power of
AC 220V or DC 220V to DC 5V for supplying the working power to
the card under through backplane also supporting another set of DC
24V supplying power to DO/HDO card under through backplane as
well. The card is designed with an isolation "power failure detection
circuit". Upon detecting that the input power is lower than the set
value, it will send out Power Fail (/PF) signal to other cards through
backplane.
