The front-end/rectifier CAR2500 1U, 2500W power-supply series provides 27W/in.³ and 92% efficiency. An onboard microcontroller with a 10-bit ADC allows for a more accurate temperature, current, and voltage-sensing capability. Additional features include an I²C, a PMBus, and Ethernet protocols. Delivering 54V dc at 46.3A for high-line operations of 230V ac, the device has a standby voltage of 3.3 or 5V at 1A to power external housekeeping and monitoring circuitry. Able to fit four units side by side in a 1U power shelf, the series supplies as much as 10,000W or 7500W N+1 redundant power. Measuring 1.61×4×14.25 in., the CAR2500 front-end/rectifier series costs $399.
