Murata Power Solutions‘ UWE eighth-brick dc-dc power modules deliver 12Vout at 120W from a nominal 12V-, 24V-, or 28-Vdc source. The UWE-12/10-Q12xx-C series’ 4:1 Vin range of 9-36V, industry standard DOSA compliant form factor, optional integrated baseplate, and high efficiency makes it well-suited for high reliability systems and systems requiring battery backup. The UWE-12/10-Q12xx-C will operate down to 9Vin, allowing longer battery discharge times in the event of a source failure. The 91+% efficiency rating of these modules also means that they will operate in harsh environments and require less cooling hardware compared to equivalent (larger) power modules. Significant overall system cost reductions can be achieved when employing this eighth-brick solution compared to equivalent quarter- or half-brick solutions.

The UWE-12/10-Q12xx-C is designed for high reliability industrial, transportation, and telecommunications equipment requiring 12-Vdc from a source of 12V-, 24V-, or 28-Vdc. Murata developed the UWE-12/10-Q12xx-C to address the need for a 12Vout dc-dc converter able to deliver 120W and provide 2250-Vdc input to output isolation from a 9- to 36-V source. Designed to offer the power systems architect options that include an optional baseplate for conduction cooling applications, positive or negative logic control and features, 2250Vdc I/O isolation, output overvoltage protection, thermal shutdown, current limit/short circuit protection, and Vout adjust (±10%).
