Original Press Release:
Quarter Brick Isolated DC/DC Converter Delivers up to 2450 W for Datacom Applications
Flex Power Modules has introduced a new device in its BMR491 series of high-density DC/DC converters with built-in digital interfaces. The new BMR491 converter can deliver 2450 W peak power for periods of up to one second, with a continuous output power rating of up to 1540 W, thus making it the highest power density digital DC/DC isolated converter available today.
It operates over an input voltage range of 48 V to 60 V and delivers a nominal 12 V output, making it suitable for data center applications. Efficiency is 97.5% at 48 Vin at half load, and the BMR491 can provide output current of up to 205 A.
The converter is supplied in an industry standard low-profile quarter-brick format, measuring 58.4 x 36.8 x 14 mm (2.30 x 1.45 x 0.55 in) with baseplate, and is also available with an integrated heatsink with a height profile of 19 mm. The converter has an operational temperature range of -40°C to +125°C.
The BMR491 uses Flex Power Modules’ proprietary hybrid regulated ratio (HRR) technology, which enables it to deliver extended power capabilities, as well as the efficiency and resilience to voltage transients that would more commonly be expected from a fixed-ratio converter.
Operating lifespan is increased through the inclusion of advanced over-voltage, over-temperature and short-circuit protection mechanisms, and mean time between failures (MTBF) is over 7 million hours. Heat dissipation is helped by the inclusion of a baseplate and the use of enhanced thermal conduction techniques, with an integrated heatsink option also being available.
As with all Flex Power Modules’ DC/DC converters, the new device complies with IEC/EN/UL 62368-1 safety standards. Input to output isolation is 1500 V.
A digital interface is available in either 4 or 7-pin DOSA standard and the BMR491 is supported by the Flex Power Designer software tool.
The BMR491 will be available in OEM quantities in the first quarter of 2021. Customers can obtain further information by contacting email@example.com.
