Introduction
1.1
Scope of the Manual
This instruction manual explains the installation and interconnection of Alpha Technologies’ CXDF 24-48/2kW.
Both the converter modules and the shelves, which the modules are plugged into, are covered in this manual.
NOTE:
To aid the user with installation, frequent reference is made to foldout drawings located at the rear of the manual.
1.2
Product Overview
The CXDF 24-48/2kW isolated DC-DC converter employs a high frequency switched mode conversion technique
to provide a fully regulated and isolated -48 Volt DC output from a +24 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.

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).
Controller software version 1.97 is the minimum requirement.
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.
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 (pre-RoHS #018-557-B2).
The optional shelf-mounted integrated model (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.
