2. Introduction
2.1 Product Overview
The CXPS-C power system provides high capacity DC power for large communications applications—central offices,
mobile switching centers, data center and cable headend facilities. The main source of power for the power system
is commercial AC power, which is converted to DC by the modular switched mode rectifiers. It is a fully automatic
system, which provides float and equalize capability for the batteries.
The basic system consists of two bays and
inter-bay copper busbars (Figure 1). The
Power bay converts AC to fully regulated
and filtered 48Vdc power, which is fed
through a load shunt to the Distribution Bay.
The system can be expanded from the
center-out to a full 12,000A capacity system
using the CXC HP controller.
The system is configurable in 4000A, 8000A
and 12000A (CXC HP) capacity.
2.2 Part Numbers and List
Options
The system offers several advanced fea-
tures with add-on list options. These list
options can be included by the customer
at time of ordering or can be added in the
future; e.g., additional Cordex HP rectifi-
ers. For more information, see the ordering
guide on the Alpha website.
