Description
The CAR2548DC series of DC-DC Converters provide highly efficient isolated power from DC input mains in a
compact 1U industry standard form factor in an unprecedented power density of 27W/in
3 . These converters
complement the CAR2548FP rectifier providing comprehensive solutions for systems connected either to commercial
ac mains, 48/60Vdc power plants or telecom central offices. This plug and play approach offers significant
advantages since systems can be reconfigured and repositioned readily by simply replacing the power supply. The
high-density, front-to-back airflow is designed for minimal space utilization and is highly expandable for future
growth. The industry standard PMBus compliant I 2 C communications buss offers a full range of control and
monitoring capabilities. The SMBusAlert signal pin alerts customers automatically of any state change within the
power supply.
