Dual Power Systems in a Diversity Array for Fault-Tolerant Applications As the power shelf systems are paired to provide an additional fault-tolerant level of dc power support, additional diversity is realized. In this array, there are two power shelf systems each with multiple protective devices linked to load apparatus. Dual power arrays will double the control and telemetry from an installation, as both systems contain communication ports. Each system will operate independently to tr...
Single Power System for Fault-Tolerant Applications The simple configuration employs a power shelf and two or more circuit protection devices, for example fuses or circuit breakers. A single power shelf system can support many A/B loads when the current requirements are low and the adequate protection devices are installed. Alternating-current (ac) diversity is managed through individual power module cord connections. Consideration given to each source of the “mains” connection can i...
What do you see or think about when viewing 2020? Will it just indicate the year for the next 360+ days*? Maybe we are thinking about the 2020 hindsight concept or reflection of doing something, anything better the next time. Perhaps we recall a memory of vision checks when one targets the “20 line” of an eye chart, striving for laser like focus. 2020 or 202 For Me - The 2020 Series of Insight Posts will encompass design discussions using power conversion equipment in 20 squared deploym...
A major U.S. university recently began a project to expand its internal private network throughout its campus. A Majorpower Power Specialist was brought in to evaluate and recommend the power equipment needed for this upgrade and backup run-time. The project’s main focus was to install new Ethernet switches at nodes which would feed back to the main campus switch. The Ethernet switches are to be installed in the telecom closets of the various node buildings throughout the campus. At the no...
