At Marway, we’re just as handy
with DC as we are with AC.

High-current connectors for DC PDU

DC Power Distribution Units

Marway has designed and manufactured numerous dc-specific PDUs as well as PDUs with mixed power forms. Dc PDUs offer the same feature sets found in ac PDUs such as conversion, conditioning, control, and monitoring, but with components specifically designed for direct current. Many designs focus on lower voltage ranges such as 24, 28, or 48 Vdc. However, we’ve designed systems to manage potentials in the hundreds of volts. One of the interesting topics for dc design is connector selection. Compared to ac, connectors for dc are much less standardized. Marway has used power pole style hermaphroditic connectors, specialized battery connectors, circular connectors, screw/lug terminals, and a variety of other styles.

  • Up to 400 A and 400 Vdc
  • DC to DC conversion to change voltage or create isolation
  • Incorporation of inverters to generate AC outputs
  • EMI filters (common/differential modes), surge suppression
  • Customized circuit branching
  • Wide variety of connectors
  • Local and remote outlet switching
  • Voltage, current, and power meters
  • Remote outlet switching over Ethernet
  • Customized enclosures from 0U to full racks

Marway’s PDU enclosures range from standard rackmount enclosures, custom non-rackmount enclosures, all the way to full-rack-sized systems. We’ve developed products for automated systems test, DVT, communications, industrial systems support, and many other applications.

Custom and Semi-Standard

While Marway specializes in custom, purpose-built PDUs, you can take advantage of designs which have already been completed.

Many of the custom products we have developed are not exclusive to their original customers, and are available as semi-standard products. You get access to more unique features like a custom design, but you take advantage of an existing design, and even make changes. For many of our customers, this approach provides a “just right” solution.

Search through the most popular semi-standard products in our Product Selector to find the combination of features you need.
