DC
voltage supply
The DIB-R5 advanced can be operated with an input voltage of 48 V
DC
.
The DC Power Distribution Module (DPDM) is used for connecting the voltage supply and
the voltage distribution to the backplane and the installed hardware components. The
DPDM is used for the V
DC
voltage supply. The V
DC
input voltage is distributed directly to
the backplane and the installed hardware components.
The following figure shows the top view of the DPDM. The following table describes it in
detail.
