1 Introduction
1.1 Manual scope
This manual covers the features and installation of the Alpha Technologies CXPS-HD 48-1.2-100 and CXPS-HD
48-1.2-225 48Vdc Power Systems.
1.2 Product overview
The CXPS-HD 48-1.2-100 and CXPS-HD 48-1.2-225 are complete integrated 48 Vdc power systems with 100 A
and 225 A capacity, respectively. Each system uses the advanced Cordex CXCM1 controller and HP 48 V 1.2 kW
rectifier modules. The HD 225A distribution panel provides front access for DC distribution circuit breakers.
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 accepts a wide range of input voltages, allowing the
flexibility to connect to supply mains rated 120/208/220/230/240/277 Vac, 50/60 Hz. The system has de-rated
output below 176 Vac input. See specifications at the end 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 includes the Alpha Cordex CXCM1 modular controller.
This system uses the controller integrated version of the controller, which is factory installed on the Cordex
rectifier system shelf.
The CXCM1 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.
