Contains electrical and thermal safety mechanisms, has excessive effiency and meets excessive security commonplace norms
Right here’s a brand new high-density DC-DC converter collection: the BMR491 that may ship 2450 W peak energy for intervals of as much as one second, with a steady output energy score of as much as 1540 W.
The converter operates over an enter voltage vary of 48 V to 60 V and delivers a nominal 12 V output, making it appropriate for knowledge centre purposes. At 48 Vin at half load, the effectivity is 97.5 per cent. An output present of as much as 205 A may be obtained.
The BMR491 makes use of Hybrid Regulated Ratio (HRR) know-how, which allows it to ship prolonged energy capabilities, in addition to effectivity and resilience to voltage transients.
Inclusion of superior over-voltage, over-temperature and short-circuit safety mechanisms assist enhance the working lifespan. Imply Time Between Failures (MTBF) is over 7 million hours. Warmth dissipation is helped by the inclusion of a baseplate and the usage of enhanced thermal conduction methods, with an built-in heatsink possibility additionally being accessible.
Provided 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 an built-in heatsink with a top profile of 19 mm, the brand new system complies with IEC/EN/UL 62368-1 security requirements. Enter to output isolation is 1500 V. The converter has an operational temperature vary of -40 levels Celsius to +125 levels Celsius.
A digital interface is offered in both 4 or 7-pin DOSA commonplace and supported by the Flex Energy Designer software program device. The BMR491 can be accessible from Flex Energy in OEM portions within the first quarter of 2021.
