Flex launches first module after Ericsson power buyout

December 04, 2017 // By Nick Flaherty
Flex Power Modules has launched its first product since taking over Ericsson Power Modules in June, with a quarter brick DC-DC advanced bus converter that can handle 1000W of power and 96.2A of peak current.

Flex Power Modules is part of the Power Division of contract equipment maker Flex and now includes 300 staff from Ericsson Power Modules and factories in Sweden and China. 

“The new BMR480 meets the demands of customers that are developing solutions based on industry leading power system designs and architectures,” said Olle Hellgren is Head of Business and Product Management at Flex Power Modules, “Able to handle very high power envelopes and peak currents up to 96A, this new advanced bus converter delivers on many different levels, in terms of high power, high efficiency and excellent thermal performance.”

With dimensions of 58.4 x 36.8 x 12.19mm (2.30 x 1.45 x 0.48 inches), the BMR480 operates from a wide 40V to 60V input voltage range and offers multiple tightly regulated (+/-2.5%) pre-programmed outputs at 10.4V, 12V and 12.5V but can be factory configured at any voltage between 9V-13.2V.

The BMR480 module employs Flex’s Hybrid Regulated Ratio (HRR) technology, which enables better use of the powertrain to deliver high-power conversion across its wide input voltage range. In addition, delivering exemplary performance for applications that operate in high ambient temperatures with limited airflow, the module offers power conversion of up to 97% efficiency – at 53V and half load – while also keeping power losses low.

As well as being ideal for intermediate bus conversion (IBC), dynamic bus voltage (DBV) and distributed power architectures (DPA), the module has been designed to power high-end and high-power applications powered by multi-cell batteries or rectifiers that are commonly used in ICT (Information and Communication Technologies) applications. Other important market sectors include networking and telecommunications equipment, industrial equipment, and server and storage applications.

Delivering higher useable power in high ambient temperature and limited-airflow environments means the BMR480 can offer high reliability. Although the module comes with a standard baseplate, it can also be connected to a heatsink or coldplate for the most extremely challenging thermal environments.
