Custom PDU Advantages

A custom pdu provides the opportunity to consolidate power management capabilities such as electrical noise filtering, power monitoring, outlet control, safety interlocks, and more into a convenient, single-enclosure solution tailored to the application. The best custom PDUs take into consideration the application's physical environment, electrical environment, and operator environment.

By stepping back, and accounting for the wider environment, the resulting PDU configuration can improve equipment reliability, reduce power distribution space requirements, and even reduce installation costs. For OEMs in particular, a self-contained power distribution module can often reduce assembly labor and help to simplify product configuration management.

Marway specializes in working closely with customers on how to configure a custom PDU which consolidates power distribution with power conversion, conditioning, control, safety, and even regulatory requirements into a single, cohesive solution. In trying to understand the advantages of custom vs. standard PDUs for your application, consider the points in the following points.

Overcome limitations of standard products

  • Meet your application’s exact needs.
  • Acheive perfect control with custom branches, switching, metering, and more.
  • Simplify installation by using the exact connectors needed.
  • Integrate safety systems with EPO and other interlocks.
  • Get the exact size and shape enclosure needed.

Protect equipment against noisy power

  • Meet EMI standards using filters and shielded enclosures.
  • Mitigate voltage spikes/transients using surge suppression.

Save space with power source consolidation

  • Consolidate ac and dc sources into one distribution system.
  • Create step up or down voltages with internal conversions.
  • Create dc from ac, or ac from dc within a single unit.

Take advantage of a team of experts

  • Reduce overall design time by using the expertise of a specialized design and manufacturing team.
  • Be assured components are properly matched for efficiency, signal quality, and reliability.
  • Let Marway manage compliance testing and certification to meet regulatory needs.

Protect Against Noisy Power

Since many signal problems are introduced to power lines through a facility’s own wiring, adding power conditioning at points throughout the facility is beneficial. An effective place to do this is in a PDU right before the application equipment. A custom pdu can incorporate application-specific solutions.

  • Protect equipment from spikes with correctly-sized surge suppressors.
  • Mitigate inducted and conducted EMI with application-matched filters and isloation transformers.
  • Minimize radiated EMI with shielding and other techniques.
  • Address application-specific needs by optimizing the selection of components for capacity matching, packaging efficiency, and cost.

Connect However You Need To

Not everything has a NEMA 5-15 plug. We get that. Because we do our own custom enclosures, we can accomodate the mounting of any connector needed.

  • NEMA, IEC, straight blade and twist locks.
  • Pin and sleeve, circular/MIL, marine connectors.
  • Multi-pin signal connectors.
  • High-current lugs and even screw terminals.

Custom PDUs can incorporate a much wider variety of power and signal connectors than standard products.

Control Whatever You Need To

A single breaker and a couple of indicators isn’t always enough. Your application is unique, and it needs unique management of circuits and controls.

  • Multiple individually breakered circuits.
  • Power consumption and power quality meters.
  • Manually switched, and remotely switched outlets.
  • Integrated EPO, remote interlocks.
  • Ethernet switching and power monitoring.

Save Space by Consolidating Boxes

Marway has specialized in the single-chassis integration of power management capabilities to reduce space, weight, and costs by eliminating redundancies. It can even save on installation time.

  • We manufacture most of our enclosures, so we get to make room for almost anything needed by the application.
  • Power supplies, step transformers, isolation transformers, EMI filters, and more can all be housed in a single enclosure.
  • Another perspective on reduced boxes—we’ve helped OEMs consolidate features of multiple PDUs to improve configuration management and reduce inventory.

All Shapes and Sizes

Marway has created custom PDUs in small custom-shaped enclosures, standard rackmount enclosures, and entire racks filled with power management and distribution hardware.

  • Traditional horizontal rackmount size of 1U and larger.
  • Vertical 0U enclosures for back-of-rack installations.
  • Non-rack enclosures from small OEM power modules to large cabinets mounted into custom framing systems.

From small, custom enclosures to traditional rackmount sizes, to large chassis with custom frames and mounting, the size and shape of Marway’s custom PDUs are almost unlimited.

Networked and Non-Networked

Connectivity is becoming an increasingly more common requirement even in traditionally non-connected environments. Marway offers Ethernet-based switching and power monitoring in addition to traditional control methods in both it’s standard products and custom PDU products.

  • Non-networked PDUs are still the backbone of power distribution when only local control is needed.
  • Non-networked PDUs can still incorporate nearby remote control for outlet switching, EPO, interlocks, and other discrete signal needs.
  • Marway’s RCM technology provides inlet power monitoring, outlet switching (and outlet current monitoring in Q1 2019) over HTTP/S, SSH, Telnet, RESTful API, and SNMP.
