Flex Power Modules adds new variants to BMR492 series

Flex Power Modules has added two new higher power variants to its through-hole, digital BMR492 range of regulated, isolated bus converters.

The BMR4920100/001 is rated at 10.4 V/67.4 A output over a 40-60 V input (80 V/100 ms), and can also deliver up to 950 W peak for less than 1 second. The BMR4920300/864 has the same input range and features an output of 12V at 66.7 A, delivering 800 W continuous, and 1100 W peak.

Both models are in the industry standard eighth-brick format - 58.4 x 22.7 x 14 mm with baseplate - and with advanced thermal management techniques achieve better than 97% efficiency at half load, with high efficiency maintained to less than 10% load. Isolation is 1500 VDC, input to output and input to baseplate, complying with IEC/UL/EN 62368 safety standards. Tight regulation is provided with typically 50µs transient load response, and pre-bias start-up is guaranteed.

The BMR492 series features comprehensive control and protection including remote on/off, input under-voltage lockout, output over-voltage, over current and short circuit protection. A PMBusTM interface is provided for remote configuration and monitoring through the free-to-use Flex Power Designer software suite.
