Scope of the Manual
This instruction manual explains the installation, interconnection, and operation of Alpha Technologies’ Cordex
24-3.1kW modular switched mode rectifier system.
NOTE:
To aid the user with installation, frequent reference is made to drawings located at the rear of the manual.

Product Overview
A complete Cordex rectifier system consists of one or more power modules in a common shelf enclosure. The
shelf has connections for AC inputs, DC output, and system communications.
Cordex rectifier modules use a high frequency, switched mode conversion technique to provide a fully regulated
and isolated DC output from the AC mains. The rectifier input is wide range to allow use on 208/220/240Vac
50/60Hz electrical service.
Rectifier power modules are “hot swappable” meaning they can be inserted or removed from the shelf without
cutting power to or from the system or the load.
Additional power modules can be included with the system at the time of ordering or added after the shelf has
been installed.
The shelf rectifier system is designed to operate with the Alpha Cordex System Controller (CXC).
The CXC allows the user to configure, monitor and control the entire DC power system from its touch screen
display similar to that used in a Personal Digital Assistant (PDA). Other features of the unit 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 of the system controller that communicate with the shelf via offset RJ-12
shelf connectors. The CXCR is mounted in a rack and the CXCP is (factory) mounted in a panel.
The CXCM4 is a 4 RU model designed for integrated use with the rectifier shelf; requires a connection interface
(adapter) for modular installation and uses the shelf space of the leftmost rectifier position (as viewed from the
front). This CXC model also has a touch screen display.
Features and details for wiring are provided in the respective chapters of this documentation package.
