Description
The CAR2548FP series of Front-End rectifiers provide highly efficient isolated power from worldwide input mains in a
compact 1U industry standard form factor in an unprecedented power density of 27W/in
3
. These rectifiers
complement the CAR2548DC converter, 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.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only, functional
operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet.
Exposure to absolute maximum ratings for extended periods can adversely affect the device reliability.
