FLEX POWER MODULES BMR4920100/001 model regulated, isolated bus converters are rated at 10.4V/67.4A output over a 40-60V input (80V/100ms), and can also deliver up to 950W peak for less than 1 second. BMR4920300/864 has the same input range and features an output of 12V at 66.7A, delivering 800W continuous, and 1100W peak. Both models are in the industry standard eighth-brick format – 58.4 x 22.7 x 14mm 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 1500Vdc, input to output and input to baseplate, complying with IEC/UL/EN 62368 safety standards. Tight regulation is provided with typically 50┬Ás transient load response, and pre-bias start-up is guaranteed.
