1 Introduction
1.1 Manual scope
This manual covers the features and installation of the Alpha Technologies CXPS 48-1.2-225 48V 225A Power
System.
1.2 Product overview
The CXPS 48-1.2-225 is a complete integrated 48 Vdc power system with 225 A capacity. The system uses the
advanced Cordex CXCM1 controller and HP 48 V 1.2 kW rectifier modules. The DCP03 300A distribution center
provides front access for DC distribution, site controller, and battery connections.
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
120/208/220/230/240/277 Vac 50/60 Hz electrical input. The system has de-rated output below 176 VAC input.
See specifications at the front of this manual.
The 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. Rectifier modules are not included with the base system, but may
be purchased along 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 CXCM1 controller.
This system uses the controller integrated version of the controller, which is factory installed on the Cordex
rectifier system shelf.
The CXC allows the user to configure, monitor and control the entire DC power system locally or remotely via a
web browser. Features of the unit include temperature compensation, auto equalization, remote access, e-mail
alarm notification, battery diagnostics, as well as web server and SNMP support for configuration and monitoring.
Details of the controller operation are provided in the software manual.
