Power module offers ‘unprecedented’ performance
Following the launch of the quarter brick BMR456, Ericsson has unveiled the second model in its Frida II 3E digital advanced bus converter family: the eighth brick BMR457.
Ericsson says the new device delivers 'unprecedented' performance to system architects developing equipment for ICT applications that require a small footprint and tightly regulated intermediate bus voltages.
The BMR457 includes a 32bit ARM based digital microcontroller that embeds Ericsson dc/dc 'Energy Optimizer' firmware to optimise switching parameters and reduce energy consumption. It is available in two input voltages ranges, from 36 to 75V with an output power of 264W, and 40 to 60V delivering 300W.
The BMR457 offers a typical efficiency of 95.2% and flat curve behavior from 20% to 100% load, which Ericsson says makes it the most efficient wide operational range advanced bus converter in its category.
"This is perhaps the first time in the power industry that a company has launched two major product innovations aimed at energy saving in power demanding applications within a month of each other," commented Patrick Le Fèvre, marketing and communication director of Ericsson power modules.
