2. Introduction
2.1 Scope of the Manual
This instruction manual explains the features, installation, interconnection and startup of the Alpha CXPS-M Cor-
dex system, both single and dual voltage. Images contained in this document are for illustrative purposes only
and may not exactly match your installation.
In addition to this manual, the following documentation may be included in the documentation package that ships
with the Alpha CXPS-M:
• Cordex Controller (CXC) Software manual
• Alpha Modular Switched Mode Rectifier System 48-4.0kW/ 48-12kW: part number 9400000-J0
• Alpha Modular Switched Mode Rectifier System 48-2.0kW/ 48-1.8kW: part number 030-807-J0
• Cordex 48-1.2kW 19" Front Access Shelf System: part number 030-834-J0
• Cordex DC/ DC Converter CXDF 24-48/2kW: part number 012-526-B2
• Cordex DC/ DC Converter CXDF 48-24/2kW: part number 012-527-B2
Product Overview
CXPS-M power systems provide a power solution for mid-sized communications applications— central offices,
data center, cell sites and cable headend facilities. The main source of power for the power system is commer-
cial AC power, which is converted to DC by the modular switched mode rectifiers. It is a fully automatic system,
which provides float and equalize capability.
These systems have many benefits:
• Flexible distribution options including plug-in breakers and TPL and TPS fuse holders
• Mid range -48V and + 24V power plants can be constructed up to 1200A using a single 4" bus arrangement
• High efficiency modular rectifiers reduce operating costs
• High efficiency modular converters for dual voltage applications
• Compact front access design reduces floor space footprint (26" x 20")
• Low voltage load or battery disconnect options
• Cordex system controller for configuration, monitoring and control of the entire DC power system from its
central panel and graphics display. Other controller features include: event data storage, alarm generation,
group rectifier configuration and remote access.
Rectifier Shelves
Rectifier shelves are wired out to the AC source provided by the customer.
Converter
For dual voltage systems, Cordex converters support small to medium 24Vdc loads from a 48Vdc power system
or small to medium 48Vdc loads from a 24Vdc power system.
Distribution Modules
A Cordex system controller is mounted in the door of a distribution module (Figure 1). An optional shunt multiplex-
er (MUX) panel (with CAN interface) can be used to monitor up to 16 channels (e.g. shunts). TPL fuse, TPS fuse
and AM breaker options are available.
2.2 Options and Additional Alpha Products
The system offers several advanced features with add-on options. These options can be included by the custom-
er at time of ordering or can be added in the future; e.g. additional Cordex rectifiers. Additional products can be
ordered separately; such as a Fusible Battery Disconnect Panel – provides a fusible battery disconnect contactor
with a control circuit to enable remote low voltage disconnect (LVD) and reset-able emergency power off (EPO).
There are status indicators for the auto disconnect, manual disconnect and remote disconnect features.
