1.2 Product Overview
The CXDF 48-24/2kW isolated DC-DC converter employs a high frequency switched mode conversion technique
to provide a fully regulated and isolated +24 Volt DC output from a -48 Volt DC input.
Each module is a stand-alone converter element, which plugs into a common shelf. The shelf provides external
connections for input, output, and alarm interfaces. Additional converter modules can increase the current
capacity and redundancy of the converter system.
Figure 1–Perspective view of CXDF 48-24/2kW converter module
The converter system consists of at least one shelf with one or more modules installed in each shelf. Additional
modules can be added to the shelf at time of ordering or at a later time after the system has been installed.
The shelf converter system is designed to operate with the Alpha Cordex System Controller (CXC).
All models of the CXC allow the user to set up, control and monitor the entire power system and ancillary
components from one central, easy-to-use source: your web browser. Other features of the controller include
temperature compensation, auto equalization, remote access, dial out on alarm, battery diagnostics, as well as
web server and SNMP support for configuration and monitoring.
Details of controller operation are provided in the current version software manual.

012-527-B2 Rev FPage 2 of 24
There are two external CXC models that can communicate with the converter shelf via offset RJ-12 shelf
connectors. The CXCR is mounted in a rack and the CXCP is (factory) mounted in a panel. Each of these models
has a touch screen display, similar to that used in a Personal Digital Assistant (PDA).
See manual #018-587-B2 (non-RoHS #018-557-B2).
The optional shelf-mounted integrated model (CXCI/CXCI+) does not have a touch screen; therefore, system
setup and management is performed exclusively with the web interface.
Details for installation and wiring are provided in the respective chapters of this documentation package.

2.1.3 Regulation and Paralleling
Cordex modular converters use “output slope” or “regulation offset” to accomplish load sharing. When the
converters are run in parallel (as is the case when more than one converter module is installed in the shelf) it is
necessary to adjust the output voltage of the individual converter modules such that the output current is shared
equally between the individual modules. At that point, the modules will track each other and share the load over
the output current range of the units. The output slope value is fixed at 1.0% (1V / full current range).
2.1.4 Reverse Polarity Protection
The converter design has incorporated reverse polarity protection from the connection to a battery on the input
and to a power source on the output. This prevents damage to the converter circuitry if a reverse connection is
made. Return of module to the factory to replace fuses will be required.

2.2 Cordex Integrated System Controller (CXCI/CXCI+) Option
The controller is mounted in the converter system shelf and brings advanced monitoring technology to the Cordex
series of converters. This compact system controller is designed for seamless operation and set up of Alpha
power systems and is equipped with the complete range of Cordex software features, including the following:
•Designed to communicate directly with Cordex converters
•Provides local and remote communications
•User definable alarms
•Daily logging of power system events and system statistics.
Behind the CXCI/CXCI+’s front panel lies the main controller motherboard, which contains a microprocessor,
memory, as well as numerous other electronic components.
The CXCI/CXCI+ includes a web server providing easy set up and monitoring using an Internet connection with
Windows Explorer.
NOTE: Details of controller operation are provided in the current version software manual.
The data logging feature allows the user to capture data from multiple inputs, for AC/DC voltages, load/battery
current, cell voltages & temperatures (automatically for up to 16 user defined logs). Typical applications of the
CXCI/CXCI+ logging include power system details, thermal performance of outdoor enclosures, battery cell
specifics, or mains variations captured by an AC voltage watchdog.
A built-in audio speaker sounds an intermittent tone during active alarms.
2.3 System Controller Front Panel
The CXCI (Figure 2) and the CXCI+ (Figure 3) controllers have a 4-digit display, for monitoring system voltage (V)
and current (A). A pushbutton toggle switch allows the user to alternate the display reading.

2.3.1 LEDs
The CXC has three LEDs located on the front panel. These are used to display the alarm status of the power
system, CXC progress and status during startup, and file transfers.
2.3.1.1 Alarm Conditions
The CXCI/CXCI+ illuminates the LED that corresponds to the system alarm status. The
following show the corresponding alarm status for each LED color:
Green OK, no alarms present
Yellow Minor alarm is present (no major alarms)
Red Major alarm is present
Only one LED is illuminated at a time during alarm conditions.
2.3.1.2 Progress and Status Indication
The LEDs are also used in the following situations:
Base unit validation – all three LEDs are on at the same time.
File transfer – when recovering from invalid firmware application – the red LED is illuminated.
2.3.2 Reset
A reset button is located on the front panel for restarting the CXCI/CXCI+ microprocessor.
Refer also to the software manual – always select the Reset menu item before pressing the reset button.
2.3.3 Modem Port (not available on the CXCI+, list 98)
The Modem port (front panel DB-9 connector, Figure 2) is designed for connection to Alpha Technologies’ Cordex
DC Modem #018-585-20.
CAUTION
Connect only Alpha-supplied modem and cable; otherwise, equipment damage can result.
2.3.4 Ethernet Port
The Ethernet port is designed for CXCI/CXCI+ connection to a user supplied network (TCP/IP secured by user)
via a front panel RJ-45 jack (Figure 2) and a standard network cable.
Local access (e.g. laptop computer) is also possible from the Ethernet port connection using a standard network
crossover cable.

2.4 Analog Input Channels
2.4.1 Voltage Inputs
Two voltage input channels, V1 and V2, provide monitoring of discharge and charge voltage. The CXCI/CXCI+
software is pre-configured to monitor V2 for load and for battery voltage. V2 is used as the system reference for
rectifier float voltage, low voltage disconnect (LVD), system high voltage alarm, and system low voltage alarm. V1
is available for additional voltage measurements.
2.4.2 Current Input
The CXCI/CXCI+ software is pre-configured to monitor I1 for load current using an external 100A/50mV current
shunt in the negative lead.
2.4.3 Temperature Inputs
Two temperature input channels, T1 and T2, provide monitoring of battery temperature and temperature
compensation (temp comp) or room/ambient temperature. A voltage is supplied to these terminals to power the
temperature sensors.
2.5 Digital Input Channels
The CXCI/CXCI+ can accommodate up to two channels and can monitor digital alarm/control signals from
converters, rectifiers, and many other types of equipment.
2.6 Alarm and Control Output Relays
The CXCI/CXCI+ contains four (4) Form C digital alarm output relays to extend alarms and control external
apparatus. Each internally generated alarm or control signal may be mapped to any one of the relays, or, several
signals may be mapped to just one relay or none at all.
2.7 Network Connection and Remote Communications
The Cordex system can be set up, monitored and tested via Ethernet 10/100 Base-T serial data connection. The
communication protocol supports a web interface. All alarming and control of Cordex converters is accomplished
with a CXC via a CAN bus.
