Operation of the Cordex
®
24-400W rectifier.
2.2. Product Overview
A complete Cordex
®
rectifier system consists of a controller with 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
120/208/220/240Vac 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 CXCi series of controllers (includes CXCi+
and CXCi HP), which is built into the rectifier system shelf.
All models of the controller allow the user to set up, control and monitor the entire power system and its
components from one central, easy-to-use source: your web browser. The CXCi series of controllers do
not have a touch screen display, system setup and management is performed exclusively with the web
interface. Details of controller operation are provided in the current version software manual.
The following figures are examples of:
1. Cordex 48-400W integrated 19" 2RU shelf system: four rectifiers, controller, and breaker
distribution.
2. Cordex 48-400W integrated 19" 2RU shelf system: five rectifiers and controller.
