DC Power for
Business-Critical Continuity™
NetSure™ 701 Series
The reliable choice for all -48VDC medium power applications
Description
Key Features
n High efficiency — 96.7%
efficient eSure™ rectifiers
ensure optimized total cost
of ownership
n High power density
(up to 115 kW) — compact
cabinet design saves space
for telecom and datacom
equipment
n Plug’n’play — easily add
or swap rectifiers and
controllers without system
interruption
n Wide temperature
tolerance — suitable
for harsh environmental
conditions
The NetSure™ 701 Series satisfies a wide range of applications from
large BTS sites to telecom COs and data centers.
The NetSure™ 701 can be installed as a single cabinet system equipped with
batteries for back up power needs. The NetSure™ 701 Series can also be configured
for multi-cabinet systems in larger sites. Bulk and semi-bulk system configurations
(see NetSure™ Bulk Series brochure for more details) are available for large power
needs.
The flexible and configurable nature of the NetSure™ 701 Series makes this the
clear choice for all medium DC power needs. Distribution units for load, battery
and AC, as well as the number of rectifiers, are all fully configurable. A variety of
cabinet height and depth options are also available.
The NetSure™ 701 Series is the most reliable
medium DC power system on the market
today. NetSure™ DC Power Systems from
Emerson offer extremely low failure rates, as
well as low total cost of ownership. To decrease
total cost of ownership even further, optional
eSure™ rectifiers with a peak efficiency rate of
96.7% are available.

R48-3500e eSure™ Rectifiers
R48-3200 Standard Rectifiers
Efficiency Without Compromise™
eSure™ rectifiers deliver the most reliability and highest efficiency in the industry, reducing power
consumption and lowering operation cost. The R48-3500e offers a peak efficiency rate of 96.7%.
Beyond reducing operating costs,
Emerson has maximized the value
of eSure™ rectifiers by making
them backwards compatible with
existing NetSure™ DC Power Systems.
Additional value is also provided
by an innovative function, known
as ECO mode, which enhances
system efficiency in existing
NetSure™systems with minimal
investment, for more information on
ECO mode, see page 6.

The NetSure™ 701 Series supports
eSure™ rectifiers as well as standard
rectifiers. The R48-3500e and
R48-3200 are both modular, high
frequency constant power rectifiers
designed with the latest patented
switch-mode technology. Plug’n’play
rectifiers allow for easy system
configuration. System capacity can
be increased by simply plugging
rectifiers into an existing shelf — no
adjustments or setup are required.

Single Cabinet Configurations
Multi Cabinet Configurations
Bulk & Semi Bulk Configurations
For power needs up to 42 kW, a complete DC power system with space for
batteries is available in a single cabinet. Distribution units for load, battery and AC, as well as the number of
rectifiers, are all fully configurable.
For power requirements from 20kW
up to more than 420kW, multi cabinet
distributed configurations integrate
dedicated rectifiers, load, battery and
AC protection into each cabinet. All
units are fully configurable and circuit
breakers as well as fuses are used for
load and battery protection.
For larger power loads, NetSure™ bulk
configurations may be suitable. These
configurations offer an increased number of rectifiers and higher power rating
than the distributed multi cabinet configurations. The load output and battery
fuses are also larger. The bulk configurations include dedicated cabinets for
rectifiers and DC outputs. The bulk and
semi bulk configurations are designed
for use with Emerson’s remote DC distribution cabinets (see NetSure™Bulk
Series brochure for more details).
NetSure™ Systems for Retrofit Applications
NetSure™ systems for retrofit applications are integrated DC power kits for retrofitting legacy DC power systems. These kits provide safe replacement and
expansion of the existing controller and rectifiers during continuous operation.
This solution improves the monitoring functions of existing legacy systems,
increasing efficiency and availability (see product data sheet for more details).

Rectifiers
Control units
With over 2 million NetSure™
rectifiers deployed in the
field, Emerson has achieved
remarkable MTBF and reliability
performance.
All NetSure™ control units are designed for robustness and are hot swappable
with a full, uninterruptible power supply. These controllers are used in Emerson’s complete range of NetSure™ DC Power systems, so the interface is well
recognized for any power system range you select (see individual data sheet for
comprehensive details on each control unit).
R48-3200
The modular
R48-3200 is a
high frequency
constant power
rectifier designed
with the latest patented switch-mode
technology. The rectifier is designed
to meet the highest requirements on
availability and reliability.
SCU+
Our standard
controller, the
SCU+, offers
world class
features including advanced alarm monitoring and
reporting. Flexible alarm settings are
programmable to support effective
relay signaling. Advanced battery
management is provided by functions
like temperature controlled charging,
boost charging, battery discharge
test, battery capacity prediction and
battery current limitation.
R48-3500e
R48-3500e is a
high frequency
constant power
rectifier with
96.7% efficiency.
The rectifier is designed to meet
the absolute highest requirements
of efficiency, energy savings, availability and reliability.
An intelligent configuration file download capability minimizes installation
time and allows planned network conformity. An RS232 serial port or the
local display is available for setting and
local/remote monitoring. The controller includes advanced remote communication through its embedded Web
server and SNMP broadcast service for
remote alarm signaling.
ACU+
The ACU+ is our
most advanced
controller, offering
all the features of
the SCU+, as well as advanced system
management. Other ACU+ features
include the patented power split function and a master / slave feature that
enables communication between
multiple controllers in very large DC
power systems. The ACU+ has the
added advantage of enabling extensive site monitoring through the use of
SM Modules.

ECO mode is a patented energy optimization software that
boosts the efficiency of already installed NetSure™ 701 systems
by simply replacing some standard efficiency rectifiers with
eSure™ rectifiers. With ECO mode, only the number of rectifiers required for normal load conditions need to be upgraded
to eSure™ rectifiers. Then, during normal load conditions, only
the eSure™ rectifiers run — while the remaining original rectifiers are reserved for charging and redundancy. The result is the
benefit of eSure™ efficiency at a fraction of the cost.
