Description

The CAR1212DC series of DC-DC Converters provide highly efficient isolated power from DC input mains in a
compact 1U industry standard form factor at a power density of 16.2W/in
CAR1212FP rectifier providing comprehensive solutions for systems connected either to commercial AC mains,
48/60V

power plants or telecom central offices. This plug and play approach offers significant advantages since

DC

systems can be reconfigured and repositioned readily by simply replacing the power supply. The high-density, front­to-back airflow is designed for minimal space utilization and is highly expandable for future growth. The industry

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.
