Emerson Network Power's DC Power Retrofit programme could help data centres reduce power losses by 80 percent, said the power and cooling solutions provider, which recently added a new solution, NetSure 701 Retrofit, to this portfolio.
The company's Malaysia-based energy system solutions director Danny Wong said current financial constraints have forced more organisations to find ways of reducing costs while extracting more value from existing infrastructure assets. "Emerson's NetSure 701 Retrofit programme is the latest addition to the programme, first launched in 2007, which allowed customers to retrofit legacy DC power systems, gaining all the benefits of a new system, at a considerably reduced cost."
"Innovation is part and parcel of the telecom business, but rapid adoption of technology has sometimes meant equally rapid infrastructure upgrades that render existing systems obsolete," said Wong, who works for the Telecom Market Management Organisation (MMO) unit Emerson Network Power Asia. "Our DC Power Retrofit programme increases the functionality of legacy products, reducing power losses up to 80 percent. And because the upgrade works within existing systems, infrastructural risks and incidences of downtime are minimal."
"The retrofit could be done on a live system with very low risk compared to a complete system change out. The retrofit technique works on legacy Emerson systems globally and can also be adapted to other manufacturers systems," he said.
Wong said the upgrade was available for Emerson -48V DC power systems, and used existing cabinets and distribution cabling. "The legacy rectifiers are replaced with more dense, powerful and more energy efficient NetSure or eSure rectifiers. These rectifiers take up a quarter of a cabinet compared to legacy rectifiers, allowing space for further capacity, additional distribution or other equipment."
Retrofitting less intrusive
"Retrofitting is a good option when efficiency and stranded capacity are the major issues," said Wong. "This option has advantages over an entirely new build-out, cost being at the top of the list. Retrofitting is much less intrusive than replacing entire systems and their payback is typically about two years. With rising demand among telco subscribers for quality, reliable service, periodic upgrades of this nature will keep telco operators competitive."
The retrofit programme, comprising NetSure and eSure rectifier technology and Emerson's Advanced Control Unit (ACU+), delivered a number of other benefits, which include advanced battery management, remote monitoring, including operational and diagnostic reports, remote service, maintenance, and remote software upgrades.
