The CP2725AC54 Front-End Power Supplies
in the Compact Power Line platform are specifically
designed to operate as an integral part of a complete distributed power system. The high-density, front-to-
back airflow rectifier is designed for minimal space utilization and is highly expandable for future growth. It
is provided with RS485 and dual-redundant I
2
C communications busses that allow it to be used in a broad
range of applications. The flexible feature set makes this front-end power supply an excellent choice for
applications requiring modular ac-to-dc bulk intermediate voltages, such as in distributed power.
