Front End And Rectifier Family Hoist Power Density

The CAR2500 Family of +12- and +48-Vdc front ends and -54-Vdc rectifiers deliver 2.5 kW from a package measuring 14.25" x 4" x 1.65" with an optional four-bay rack that packs 10 kW of power into a 19", 1U profile. With a power density of 27 W/in.3, the components perform with an efficiency of 92%. They rely on a microcontroller to provide accurate temperature, current, and voltage sensing and support interfaces such as I2C, PMBus, and Ethernet protocols. Other shared features include a standby voltage of either 3.3V or 5V at 1A, thermally controlled fan, hot-swap redundancy, active single-wire current sharing, output-voltage programming, current readout, remote on/off, and front plate LEDs. Protection features include input over and under voltage, output over voltage, over temperature, and over current. Prices start at $685 each/500. Price for the optional power shelf is $380.
