Technology Overview

Consolidate: do more, use less.

Distribution, and more

With Marway’s ability to create PDUs for unique applications, the PDU becomes an ideal place to consolidate many power management needs of electrical platforms. This includes conditioning incoming power to minimize noise, converting available power to other forms, adding controls for safety and operator convenience, and integrating monitoring to display power conditions and status.

We call these capabilities the pillars of power management. Each represents a set of features which build upon the power distribution foundation to create a uniquely optimized solution.

Power Conversion

Power distribution units are commonly used to branch single power sources to downstream equipment. However, many installations of electronic equipment require more than one type of power source. There can be advantages to consolidating multiple power sources and adding power conversion into a single PDU. Using transformers (ac to ac), power supplies (ac to dc), converters (dc to dc), and inverters (dc to ac) we can optimize space, weight, cost, and even simplify the installation and operation of electrical systems. See our complete power conversion white paper.

Power Conditioning

Modern electronic equipment requires clean, stable power, free of noise, in order to perform reliably. Most facilities have imperfections in their power signals which can cause poor performance, incorrect functionality, or even damage. Most electronic equipment has limited built-in protection against these imperfections. There’s a basic assumption that incoming power is clean. Marway can consolidate power conditioning needs into the PDU using EMI filters, transformers, varistors, and other features to assure a clean and stable power signal to all connected equipment. See our complete power conditioning white paper.

Power Control

Control capabilities in PDUs offer a range of options including switches, breakers, remote signals across Ethernet, and even automated switching between power sources. Whether for safety, redundancy, or convenience, consolidating power control features into the PDU can help reduce the complexity, cost, and packaging of a power distribution application.

Safety considerations of power control include over-current protection and easy access to power shutdown for emergency conditions. Safety aside, most controls are added to PDUs for operator convenience. Circuits and outlets can have on/off control through local breakers, switches, or relays, through remote panel switches, or even through software over an Ethernet network. See our complete power control white paper.

Power Monitoring

Power monitoring with digital displays and status indicators provide confidence that downstream equipment is getting what it needs. This might include capabilities to allow tracking of power quality, available capacity, and simple on/off status of circuits or outlets. If the PDU is not visible, remote panels with these features are also possible. Whether for local visibility, or remote connectivity to factory automation, Marway can consolidate power monitoring needs into the PDU to optimize power management space and cost.
