- Product Line: DC Converter Modules
The CXDF 48-57/2kW DC-DC Converter is a modular converter system that produces a constant 57Vdc output independent of fluctuations in input voltage. Additionally, it complies with IEEE 802.3af PoE requirements. When combined with the Alpha eLimiter, the CXDF 48-57 enables service providers to extend the reach of line powered Indoor Distributed Antennae Systems (iDAS).
Unlike other line powered solutions, the CXDF 48-57 is controlled by Alpha’s Cordex CXC system controller. The intelligent controls enable local and remote setup, adjustment and control in a simple single-step. By utilizing TCP/IP technology, complete configuration and monitoring of power equipment is possible through a network Web browser.
Cordex DC-DC converters bring advanced technology to the DC power industry. Innovative engineering combines the best in efficiency and reliability, meeting a wide array of power requirements. The 48-57 converter system is a perfect solution for supplying 57Vdc steady output voltage independent of input battery voltage (that may vary from 42 to 54V) depending on state of charge.
The fan-cooled CXDF 48-57/2kW converter has extremely high density, providing the most power in the least amount of space. Each 19" shelf can accommodate up to 4 compact 2RU modules to provide redundancy and higher output. The converter system can be controlled and monitored by a central Cordex CXC controller and optionally via a shelf integrated CXCI controller solution for stand alone operation.
Local and remote setup, adjustment and control is a simple single-step process with the Cordex CXC system controller. By utilizing TCP/IP technology, complete configuration and monitoring of power equipment is possible through a network web browser.
