Delta H48SC28016 Series

Delta H48SC28016 450W DC-DC power module

The H48SC28016 is a 36V to 75V input, isolated single output, half brick, full digital control DC-DC converter. It provides up to 450 watts of power in an industry standard, DOSA compliant footprint and pin out; the typical efficiency is 95% at 48V input, 28V output and 16A load. There is a built-in digital PWM controller in the H48SC28016, which is used to complete the Vo feedback, PWM signal generation, fault protection, and PMBUS communications. With the digital control, design and application flexibility, advanced performance, and reliability are obtained.

3M has presented New 3M™ 100G QSFP28 Direct Attach Copper Cable Assemblies, 9Q Series are passive copper cable assemblies which utilize 3M Twin Axial Cable technology to create a highly-flexible, foldable, high-performance solution.
