AC-DC Power Supplies

Written by Sam Wallace

AC-DC power supplies are of fundamental importance to the embedded systems they power. Vendors continue to innovate and improve power supplies and converters to meet the demands of multiple industries, including requirements such as miniature form factors or rugged durability and efficient cooling in wide temperature ranges. The products selected for this month’s Datasheet are just a small sample of these recent innovations.

  • AC-DC Power Supplies
  • Aimtec AMESP500U
  • Astrodyne MCA-10
  • Cincon CMB70S
  • CUI PSK-60D
  • Mean Well LRS-150
  • Murata Power Solutions BCA1
  • RECOM Power PACM30-K/277
  • TDK CUS250M
  • XPower ASB160

The AI revolution will never arrive without power. If I produced power supplies for embedded systems, that would be my tagline. That kernel of marketing brilliance aside, it remains true that power has a major influence on the size, cooling, and mobility of any system, and thus AC-DC power supplies are critical to the design and functioning of embedded technology. So while the limelight has long since been stolen by flashy new chips built for Artificial-Intelligience-of-Things (AIoT) at the edge, vendors persist in producing ever more efficient and compact AC-DC power supplies to meet the needs of those flashy chips and the rapidly evolving market.

Hence this month’s gallery of the latest in AC-DC power supplies. No single trend captures the latest from these companies. Many products are geared toward providing wide operating temperature ranges, including in still-air environments. In line with this, many manufacturers emphasize their device’s cooling methods and efficiency. Others have smaller aspirations: literally, designed to fit ultra-compact systems. Durability, safe isolation, and of course wide voltage ranges are other common concerns on the following pages. And in a space full of niche, industry-focused design, many vendors have opted instead to make their power supplies as flexible and wide-reaching as possible.
