Vicor — Supplies the Ever-Growing Power Demands of Today’s Applications

FTMJan2018-AS-Vicor-tile-200x200

Designs are only increasing in capability and only increasing in power consumption. Across industries, engineers are finding the value of 48V in enabling more power for their designs. Vicor DC-DC converter and regulator modules enable the advantages of 48V while pushing the boundaries of conversion efficiency, density and cost.

Vicor – Why are Power Designs Moving to 48V?

FTMJan2018-DN-Vicor-tile-200x200

Today’s applications are increasing performance by adding: More processing capability Higher communication rates Longer run rates Added peripherals More torque Brighter LEDs To deliver “more” requires more power to be delivered. More power typically is constrained by size and/or weight restrictions. This is why a growing number of industries are moving to higher voltage, 48V distribution versus conventional 12V distribution.
