DC Power for
Business-Critical Continuity™
NetSure™ 701 Retrofit
-48V DC Power Systems
Key Features
Description
nCost effective way to add new
technology and increase
reliability without replacing the
entire system
NetSure™ systems for retrofit applications offer a cost efficient way to upgrade and
expand an existing power system while keeping the present infrastructure (cabinet
and mechanics) intact. Old rectifiers are replaced with new NetSure™ rectifiers,
substantially improving both system power efficiency and reliability. Also included
in this solution is an advanced control unit for site monitoring.
nIncreased system efficiency,
up to 96%
These NetSure™ systems can be installed on live systems with no interruption of
service. Compared to replacing the entire system, this type of upgrade significantly
reduces risk and installation time.
nCan be installed on live systems
nIncreased power in existing
footprint
nHigh efficiency rectifiers with
lower power losses reduce the
site’s cooling needs
nEliminates rectifier legacy
support issues
nEnables connection to remote
monitoring (ENEC, SNMP
and web)
An upgrade of a legacy system using a NetSure™ system increases both reliability
and efficiency. By using Emerson’s high-efficiency eSure™ rectifiers, the upgraded
system can reach 96% system efficiency. In addition to this, Emerson’s advanced
control unit enables supervision, comprehensive monitoring and maintenance with
remote management connectivity.
NetSure™ retrofit systems currently exist for Emerson, Ericsson, Nortel and other
legacy DC power systems. Additionally, we can easily adapt the solution to your
power plant needs.
Application
Designed for existing -48Vdc power plants with requirement for replacement and
expansion of power plant capacity.
nAdvanced control unit enables
use of hybrid energy sources
