CXCM4 Features
The CXCM4 (Cordex Controller, Modular, 4RU) is mounted in the rectifier system shelf and brings advanced
monitoring technology to the Cordex series of rectifiers. This compact system controller is designed for seamless
operation and set up of Alpha power systems and is equipped with the complete range of Cordex software
features, including the following:
•
Designed to communicate directly with Cordex rectifiers
•
Includes battery temperature compensation charging
•
Battery performance diagnostics
•
Provides local and remote communications
•
User definable alarms
•
Daily logging of power system events and system statistics.
Behind the CXCM4’s front panel lies the main controller motherboard, which contains a microprocessor, memory,
as well as numerous other electronic components.
The CXCM4 includes a web server providing easy set up and monitoring using an Internet connection with the
standard Windows Internet Explorer browser.
The data logging feature allows the user to capture data from multiple inputs, for AC/DC voltages, load/battery
current, cell voltages & temperatures (automatically for up to 16 user defined logs). Typical applications of the
CXCM4 logging include power system details, thermal performance of outdoor enclosures, battery cell specifics,
or mains variations captured by an AC voltage watchdog.
A built-in audio speaker sounds an intermittent tone during active alarms.
The input/output (I/O) board houses a series of terminal connections; located at the back of the system shelf.
