The MPR and CAR-series Front-End rectifiers and DC/DC power supplies provide highly efficient isolated power in a compact, 1U industry-standard form factor, providing a high power density of 30W/in3. The power supplies are ideal for applications where mid to light-load efficiency is significant – given the nature of the power consumption of the end application. The MPR and CAR-series rectifiers provide comprehensive solutions for systems connected to commercial AC mains, power plants or telecom central offices.

The plug-and-play products offer significant advantages as systems can be reconfigured and repositioned readily by simply replacing the power supply. The high-density units feature front-to-back airflow for minimal space utilization. The power supplies utilize an industry-standard PMBus-compliant I2C communications bus, offering a full range of control and monitoring capabilities while the SMBAlert signal pin alerts customers automatically of any state change within the power supply.
