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.

4.1 Power Bays
4.1.1 Cordex HP System Controller
The Cordex HP system controller, mounted in the primary power bay, provides easy access to controls and display
status. The controller provides comprehensive setup, control, monitoring and communication for Alpha DC power
systems.
Controller features include the following:
• Designed to communicate directly with HP rectifiers
• Includes battery temperature compensation charging
• Battery performance diagnostics
• Provides local and remote communications
• User definable alarms
• Daily logging of power system events and system statistics
• Active low voltage disconnect (LVD)
See the controller manual shipped with your order for detailed information.
4.1.2 Cordex HP Rectifier Shelves
A 4000A power bay has eight rectifier shelves and a 2000A bay has four rectifier shelves. Each rectifier shelf can
hold up to six Cordex HP 4kW rectifier modules or two 12kW/480 rectifier modules.
A Cordex HP 4.0kW rectifier supplies a nominal output of 74A at 54Vdc and the 12kW/480 rectifier supplies 222A
at 54Vdc nominal. Rectifier specifications are included in the Cordex HP rectifier manual included with the system
documentation package.
The controller provides central control of the rectifiers’ output level, load sharing, temperature compensation, low
voltage disconnect on the distribution bay and alarm reports. A CAN bus cable is wired or daisy-chained to each
rectifier shelf for communication with the controller.
4.1.3 AC Termination Wiring
The required input voltage depends on the rectifier options chosen at the time of ordering. The AC distribution as-
sembly at the top of each power bay provides front access AC overhead termination.
A split AC terminal box allows for feeds from two separate sources. Eight feed is standard; six or sixteen feed is an
option. See the specifications in Chapter 3 on page 9.
4.1.4 Standalone or Add-on Power Bays
A standalone power bay can replace multiple bays with less capacity in an existing power system or as an add-on to
upgrade the capacity of an installed CXPS-C power system.

9400001-J1 Rev F

4.1.5 Power Bay DC Charge Buses
Each standalone power bay has two vertical charge bars con-
necting all return terminals and all negative terminals of the recti-
fier shelves (Figure 3). These busbars are rated for the maximum
current supplied by the rectifier shelves.
In a multi-bay power system, the return vertical busbar connects
to an inter-bay return bar located across the top of the power and
distribution bays. Similarly the -48V vertical busbar connects to
an inter-bay -48V busbar, which terminates at the system shunt
located in the distribution bay.
Figure 4 shows a top view of the horizontal busbars between a
power bay and two distribution bays.

4.2 Rectifier Modules
The rectifier modules are "hot swappable" allowing for quick replacement and easy maintenance of the system.
(They can be inserted or removed from the shelf without removing AC power or shutting down the entire system.)
4. 2 .1 Rectifier Alarms and LEDs
Rectifier status, such as mains OK, Minor and Major alarms, display on the rectifier front panel.
A rectifier Major alarm indicates, the module has shut down due to a critical fault.
A rectifier Minor alarm indicates the module has a non-critical alarm, however, it has not shut down.
See the Cordex HP rectifier manual included with the system documentation package for detailed information.
