Murata Power Solutions’ UWE eighth-brick DC/DC power modules are the industry’s first eighth-brick to deliver 12Vout at 120W from a nominal 12V, 24V, or 28Vdc 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 ideal 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 an ideal choice for high reliability industrial, transportation, and telecommunications equipment requiring 12Vdc from a source of 12V, 24V, or 28Vdc. Murata developed the UWE-12/10-Q12xx-C to address the need for a 12Vout DC-DC converter able to deliver 120W and provide 2250Vdc input to output isolation from a 9-36V 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%).
The UWE-12/10-Q12-C isolated DC/DC power converter represents the next generation converters in the industry standard eighth-brick package with up to 120W of available output power. These DC-DC converters are designed for systems employing distributed power architectures or intermediate bus architectures in applications that include but are not limited to battery charging/back-up systems, telecommunications, lighting applications, motor control, and anywhere that 12V @ 120W is required from a 9-36Vdc source including applications where extreme operating temperatures will be required The modules feature an operating temperature range of -40 to 85°C.
Bill Smith, the Director of Marketing for Murata Power Solutions, comments, “We are proud to offer the industry’s first eighth-brick DC/DC power module that will deliver 12Vout @ 120W from a 12 or 24Vdc source. The UWE series utilizes proprietary circuit architectures and the latest component and materials technology to provide next-generation system designers with the highest performing power conversion modules in the industry.”
