FLEX POWER MODULES BMR4912510/871 digital, quarter-brick dc-dc converter delivers a nominal 24V output from a 40-60V input at a power level of up to 1300W. While its output voltage is nominally 24V, a control adjustment using its 4-pin PMBus digital interface allows 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 it particularly useful to support battery management solutions used in remote radio base station installations for example, as well as other applications where conversion from 48V to 24V is necessary at high power levels. Device has a small form factor (58.4 x 36.8 x 14mm) and is 97.1% efficient (for a 54V input voltage at half-load). These make it suitable for space-constrained applications where thermal management can be a concern. The operating temperature range for the product is -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.
