2. Introduction
2.1 Scope of the Manual
This instruction manual explains the installation, interconnection, and operation of the Alpha Cordex 48-3.6kW,
48-4.0kW and 48-12kW modular switched mode rectifier systems.
2.2 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 208/220/240 Vac
50/60 Hz electrical service.
Rectifier power modules are “hot swappable”—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 con-
troller allows the user to configure, monitor and control the entire DC power system from its touch screen display
including 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 options for the Alpha CXC
• External CXC models of the system controller communicate with the shelf via offset RJ-12 shelf connec-
tors. The CXCR is mounted in a rack and the CXCP is (factory) mounted in a panel.
• The CXCM4, 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.
