Flex Power extends eighth-brick DC/DC range


New device achieves 96 percent efficiency at half load

Flex Power Modules has added a new part to its BMR492 series which now features a wide 36-75 V input range for telecom/PoE applications.

The through-hole BMR492 0311/011 provides a regulated 12 V output rated at 504 W / 42 A adjustable from 8-13.2 V, and achieves 96 percent efficiency at half load. Monitoring and control functions are provided via an optional PMBus interface and the part is supported by the Flex Power Designer tool for easy set-up and characterisation in customer application circuits.

The BMR4920311/011 has a 2250 V isolation rating and features an optional baseplate for effective heat transfer to an attached heatsink. The part is halogen-free and is fully protected against short-circuits, output over-voltage, over-temperature and input under-voltage. The product is in the industry-standard eighth-brick format, measuring 58.4 x 22.7 x 12.7 mm with baseplate fitted.

Olle Hellgren, director product management and marketing of Flex Power Modules comments: “The BMR492 is a great solution for power-dense data centre DC/DC conversion and now it can be used in traditional telecom applications as well which need the wider input voltage operation”.
