ABB Adds DC-Input Version to Power Supply Family


New DC-input version creates additional options for customers looking for compact, high-density, hot-swappable power supplies

Providing additional input options for customers, ABB is expanding its line of compact, energy-efficient MPR power supplies with a new DC-input version. Both the AC-input and DC-input power supplies feature 9-by-2.15-by-1.57-inch form factors, offering one of the most compact options available today, when it comes to power supply depth.

The MPR0712TE (AC-input version) and MPR0712DC (DC-input version) medium-power units are interchangeable, offering greater flexibility in end application designs that require both input options. The MPR products achieve power densities of 23 watts (W)/inch3 and energy efficiencies of up to 94 percent at 50 percent load, achieving an 80 PLUS Platinum grade.

The MPR0712TE features a front 90-to-264-volt AC input, rear +12-volt DC output, and a 700- W output power. The MPR0712DC allows for a front -44 to -72-volt DC input and a rear +12- volt DC output with a 700-W output power. Both the AC and DC versions can operate over a wide temperature range of -5 C to 50 C.

The 9-inch-long, hot-swappable power supplies are well-suited for 12-volt distributed power architectures, mid-end and blade servers, networking equipment and attached storage, routers and switches, as well as advanced workstations. Both the AC and DC versions feature a PMBus-compliant I2C communications bus, allowing electrical engineers to integrate a range of monitoring and control capabilities into their system designs.

The power supplies are packed with additional features such as active current sharing, remote sensing ability, and a 12-volt standby output voltage. The MPR power supplies also feature built-in overvoltage, overcurrent and overtemperature protections, helping to improve safety and reliability.
