48Vdc Modular Battery Charger

Switched Mode Rectifier System up to 250A

A complete rectifier system consists of one or more power modules in a common shelf enclosure. The shelf has connections for AC inputs, DC output, and system communications. The wide AC input operating range for global installations and wide operating temperature ranges for installation in uncontrolled environments along with high efficiency (>96%) reduces the carbon footprint and the operating expenses.

Our rectifier modules use a high frequency, switched mode conversion technique to provide a fully regulated and isolated DC output from the AC mains. Multiple 48V configurations are available up to 250A in a compact 1RU shelf system. Industry leading power density (28W/in3) yields more space for revenue generating equipment.

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 shelf rectifier system is designed to operate with the Cordex System Controller (CXC). This controller allows the user to configure, monitor and control the entire DC power system from its touch screen display which includes temperature compensation, auto equalization, remote access, dial out on alarm, battery diagnostics, as well
as Web server and SNMP support for configuration and monitoring. Details of controller operation are provided in the current version of the related software manual.

External CXC models of the system controller communicate with the shelf via RJ-12 shelf connectors. In a power system, up to five (5) rectifier shelves may be stacked and connected to the same controller. The latest CXC-HP controller, featuring touch screen, color LCD display with front Ethernet and USB connectors, is available as a panel
mount controller or as part of the CXPS-E3 system.
