Baseplate-cooled supplies deliver 355 W

The VBM-360 series compact ac/dc power supplies feature baseplate-cooling and power density of 14.8 W/in³ , providing 355 W in an industry standard footprint. The supplies are housed in an open frame version measuring 5 x 3 x 1.6-in. and an enclosed version measuring 5.39 x 3.425 x 1.7-in.

The power supplies feature typical efficiency above 93%, and target applications where forced-air cooling is not preferred due to audible noise or space limitations. The supplies cosst $183.00 each in quantities of 100 units and is suited for sealed-box applications where heat must be conducted through the chassis. It uses a 90 to 264 Vac input and provides single outputs of 12, 24 and 48 Vdc. It uses conduction-cooling via an integrated baseplate, the 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.
