Rectifiers
The AN2016 cabinet offers the MPR25 25A rectifier in combinations of one
to five plug-in modules mounted in the NT5C10CP-61 rectifier shelves (see
Figure 2-27).
The rectifiers provide n+1 redundancy.
The rectifiers perform the following:
• power the installed equipment
• power the cabinet fans
• provide battery charge current
The output voltage of the MPR25 25A rectifier is adjustable from -44 V dc to
-56 V dc and is nominally adjusted to provide an output of -55 V dc.
The voltage must be adjusted according to the type of battery selected. To
adjust the output voltage regarding the MPR25 25A rectifier, refer to
“Description, Installation, Operation and Maintenance Manual”,
169-2071-500.
DANGER
Fire hazard
Remove all paper and any other combustible materials from
inside the cabinet before you power up the cabinet.
