CUI’s latest baseplate-cooled Ac-Dc power supplies deliver 355 W at 93.5% efficiency

CUI Inc has unveiled a new family of compact ac-dc power supplies featuring baseplate-cooling. The VBM-360 series offers high power density of 14.8 W/in3, providing 355 W in an industry standard footprint. The space-saving power supplies are housed in two optional case styles: a compact open frame version measuring 5 x 3 x 1.6 inches (127.00 x 76.00 x 40.60 mm) and an enclosed version.

Featuring typical efficiency above 93%, the power supplies are designed for applications where forced-air cooling is not preferred due to audible noise or space limitations. The VBM series is also suited for sealed-box applications where heat must be conducted through the chassis, a common requirement in commercial and industrial equipment that’s designed for outdoor and harsh environments.

The VBM-360 power supplies have a universal 90~264 Vac input for global operation and are available with single outputs of 12, 24 and 48 Vdc. Utilizing conduction-cooling via an integrated baseplate, open frame models are rated for operation at 80% from -20°C to 40°C ambient, derating to 40% load at 70°C, while enclosed versions are rated for operation at 100% load from -20°C to 40°C, also derating to 40% load at 70°C. For applications that can incorporate air flow of 10 CFM, the open frame units will operate at 100% load from -20°C to 50°C, while enclosed versions will operate at 100% load from -20°C to 60°C.

The VBM-360 series features include active power factor correction (PFC) and protections for over voltage, over current, short circuit, and over temperature. Connections for remote on/off control, remote sense, 5 V standby, and a 12 V fan output are also included. All models carry UL/cUL and TUV 60950-1 safety certifications for ITE, commercial and industrial equipment, and are compliant with the EN 55022 Class B EMI standard.

The VBM-360 power supply is priced at $183.00 each in quantities of 100 units. Please contact CUI for volume pricing.
