Emerson Network Power Launches New 120kW 400V DC Power System
NetSure™ 9500 expands industry-leading 400V DC power platform.
Emerson Network Power has introduced the NetSure™ 9500 400V DC power system for telecom, data center, and commercial building applications. The NetSure 9500 is the latest offering in Emerson’s industry-leading line of 400V DC power solutions.
Based on the same architecture used in the 30kW NetSure 4015 system — including Emerson’s patented 15kW eSure™ rectifiers — the 120kW NetSure 9500 is Emerson’s largest 400V DC offering. The system’s modular design enables deployment in a variety of configurations and allows for scalable growth to avoid stranded capacity and wasted floor space while delivering proven NetSure efficiency and reliability.
“Emerson has been a pioneer in the development of 400V DC power, and the expansion of our 400V DC portfolio better allows us to provide innovative solutions for customers in the telecom, data center, and commercial building industries,” said Thomas Bennett, vice president, product management, for the Energy Systems business of Emerson Network Power. “The NetSure 9500 provides an alternative to traditional -48V DC power systems in the telecom space and to AC UPS systems in data centers. It also is a natural fit for commercial buildings, where DC microgrids that integrate distributed energy sources are increasingly common.”
The NetSure 9500 includes a power module containing sections for power conversion, controls and distribution, a distribution module for extended load distribution positions, and a battery cabinet containing one string of VRLA (valve-regulated lead–acid) batteries. The system’s fault-tolerant design with hot-swappable rectifiers and controls limits downtime.
For telecom providers, the move from -48V DC to 400V DC decreases current and correspondingly reduces the amount of copper needed for transport, reducing cabling material and installation costs by up to 80 percent. The advantage for data centers lies in the simplicity of the power chain, reducing not only conversions but potential points of failure, and thereby delivering availability that has been the hallmark of DC-powered telecom networks for decades. In fact, the first deployment of the NetSure 9500 is by Steel ORCA, a U.S.-based co-location company that provides both AC and DC solutions to its clients.
“We recognize that the industry is looking for ways to maintain or improve reliability while maintaining or reducing cost,” said Dennis Cronin, chief operating officer of Steel ORCA, which worked with Emerson Network Power and StarLine DC Solutions on the turnkey power solution that includes the NetSure 9500. “Our unique hybrid approach delivers on the promise of DC power, which is guaranteed to our clients if they choose the dcDC (direct current data center) area of our center. To help potential clients better understand the implications, we are building a dcDC Demonstration Room with our industry partners.”
The NetSure 9500 adds to Emerson’s 400V DC power portfolio, which now includes the NetSure 4015 and the NetSure 721 with 400V DC input, a 400V/-48V DC–DC converter system that enables existing -48V DC power equipment to be powered off of 400V DC distribution.
