The CP2000AC54 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 many features including PoE isolation, RS485 and dual-redundant I2C 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.
