- High power variant delivering up to 1300W
- 24V nominal output voltage adjustable down to 0V
Flex Power Modules’ latest addition to its BMR491 range of digital, quarter-brick DC/DC converters is the BMR4912510/871, which delivers a nominal 24V output from a 40-60V input at a power level of up to 1300W.
Whileits output voltage is nominally 24V, a control adjustment using its 4-pin PMBus® digital interfaceallows this to be set from 16-26.4V nominally, but it can be further adjusted down to 0V if needed. This wide adjustment range makes itparticularly useful to support battery management solutions used in remote radiobase station installations for example, as well as other applications where conversion from 48V to 24V is necessary at high power levels.
The BMR4912510/871has a small form factor (58.4 x 36.8 x 14mm) and is 97.1% efficient (for a 54V input voltageat half-load). These make it suitable for space-constrained applications where thermal management can be a concern.
The operating temperature range for the BMR4912510/871is -40°C to +125°C and it provides 1500V input-output basic isolation for compliance with IEC/EN/UL 62368-1 and offers full protection against over-temperature, input under-voltage and output over-voltage, over-current and short circuits.
This converter is also supported by the freely available ‘Flex Power Designer’ software for remote configuration, control, and monitoring.
Olle Hellgren, Director of Marketing and Product Management atFlex Power Modulescomments“TheBMR4912510/871 is unique in its ability to deliver up to 1300W of output power and provide an output voltage that can be adjusted from effectively 0V to as high as 26.4V. We believe that power management companies supplying the telecoms base station manufacturerswill benefit from the flexibility of such a digital DC/DC solution.”
All variants are available in OEM quantities.
