1 Introduction
1.1 Scope of the Manual
This instruction manual explains the installation, interconnection, and operation of the Alpha Cordex CXRF-
HP 48-1.2 kW 48 Vdc power and distribution systems. Listed below are the four available configurations:
•
1RU shelf system, 3 rectifier modules, with CXCM1 controller and GMT fuse distribution (Figure 1)
• 1RU shelf system, 4 rectifier modules, up to 4800W output power with CXCM1 controller (Figure 2a)
• 1RU shelf system, 5 rectifier modules, up to 6000W bulk power output (Figure 2b)
• 2RU shelf system, 4 rectifier modules, up to 4800W output power, with CXCM1 controller, breakers
and GMT fuses distribution (Figure 3)
NOTE: To aid the user with installation, reference is made to drawings located at the rear of the manual.
1.2 Product Overview
• Designed specifically for restricted space installations, these 48Vdc power distribution systems
incorporate the HP (High Performance) series of 48V 1.2kW Cordex rectifier modules.
• Complete front access design, allowing for all customer connections in front of the rack channel.
• 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 Cordex CXRF-HP 48-1.2kW rectifier model
input is universal to allow use on 120/208/220/240Vac 50/60Hz 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 shelves are designed for horizontal mounting in a 19" or 23" center mount installation via universal
mounting brackets (EIA rack spacing) and utilize dual IEC-type connectors for multiple AC line cord
solutions.
• The Alpha Cordex CXCM1 was designed as a modular CXC controller for the Cordex CXRF-HP 48-
1.2kW rectifier series. Details for installation and wiring are provided in the respective chapters of this
documentation package.
• All models of the CXC allow the user to set up, control and monitor the entire power system and
ancillary components from one central, easy-to-use source: your web browser. The CXCM1 model
does not have a touch screen display; therefore, system setup and management is performed
exclusively with the web interface. Details of controller operation are provided in the current version
software manual.
• The equipment is suitable for installation in Network Telecommunication Facilities.
• The distribution component uses up to four bullet-type breakers and up to ten GMT fuse positions. The
distribution module also allows for termination of two battery strings and includes a 125A battery shunt.
