Description
The NetSure™ 211 DC Power Solution is a flexible system capable of providing DC
power through the use of 500W or 1000W rectifiers and a variet y of output distribution options. The system is available in an integrated distribution configuration. The
NetSure
suited for up to 6kW power requirements in the most harsh environments. The
system is supported by a single SCU+ or ACU+ controller (ACU+ for 2RU systems only)
that provides all control and operational conditions, as well as historical site data and
external signal conditioning and monitoring. Each rectifier shelf includes a slot for
the controller and space for the rectifiers. Distribution is provided by breakers or
fuses located in the power shelf.
Distribution options include load low-voltage disconnect (LLVD), battery low-voltage
disconnect (BLVD), or no low-voltage disconnect. Plug-in rectifiers, AC connectivity
and DC load outputs enhance the overall flexibility of the system by minimizing
installation and start-up time. This dynamic system also offers alternative AC input
configurations, relay rack configurations, battery tray options, battery box options
and pre-configured output load kits.
The NetSure
cost-effective solution is NEBS Level 3 compliant and UL Listed. Rated for continuous
operation from -40°C to +75°C, this system is designed for the harsh outside plant
environment, as well as customer premise FTTx, wireless back-haul, microwave, and
DLC applications.

The NetSure™ 211 is especially designed for all types of access
applications in both fixed and wireless access networks, offering
unmatched site installation flexibility.

conditions (see diagram 1), making them
especially suitable for high-temperature
environments. In a system with rectifiers
operating at 65°C, the output is still 60%

Extremely wide AC voltage range window
The AC voltage input range vs. rectifier
output is another extraordinary feature of
this small system. The 1000W rectifier will
deliver full power from 176 VAC to 300 VAC.
From 85 VAC to 176 VAC the power level
is derated (see diagram 2). The 500W
rectifier will deliver full power from 104
VAC to 300 VAC.

The NetSure™ 211’s extensive battery
management capabilities, easy configuration
and maintenance are all backed by the
resources and quality reputation of a
worldwide service organization.
Basic Configurations
Two core configurations define the combination of
rectifier and distribution shelves and determine the
ultimate capacity of the system.
Internal Distribution up to 3kW
Our most compact system measures 1RU high with distribution capability and rectifiers in the same shelf. Available in
19" and 23" widths, the system provides distribution space for
Internal Distribution up to 6kW
The 2RU high configuration is also available in 19" and 23"
widths with distribution capability and rectifiers in the same
shelf. The system provides distribution space for GMT fuses up
(10) GMT fuses up to 15A. Configuration options
include battery low voltage disconnect (BLVD) or no
low voltage disconnect.
to 15A or a combination of circuit breakers up to 100A and
GMT fuses. Configuration options include battery low
voltage disconnect (BLVD), load low voltage disconnect
(LLVD), or no low voltage disconnect.

Rectifier Shelves
The rectifier shelves integrated into the
NetSure
(1RU) or 3.5" (2RU) high and available
in 19" and 23" widths. These shelves
provide front to back ventilation and
can be mounted directly above or below
other electronic equipment, maximizing
revenue-generating space. Each unit
™
211 system are either 1.75"
will operate from 120/208/240VAC and
is equipped to accommodate plug-in AC
connections or open wire line cords.
DC output connection options for each
shelf include terminal blocks, plug-in
DC jumpers for GMT load, and two-hole
compression lugs for breakers. The shelf
with rectifiers is UL Listed and meets FCC
Class B EMI/RFI requirements.
As load demand grows, the system can be easily
expanded with additional modular components.
Rectifiers
The R48-500 and R48-1000 NetSure™
rectifiers are rated for 500W or 1000W
watt constant output power when
operated at 208/240VAC nominal input.
The 1000W model rectifier provides
approximately half its rated output when
operated at 120VAC. This auto-sensing
circuit enables each rectifier to automatically adjust its output to the available line
voltage. The rectifier will provide up to
100% of rated power at 45°C.
As the temperature increases from 45°C
to 75°C, the thermal power limit circuit
linearly decreases power. In the typical
operating range, these rectifiers have
a total harmonic distortion less than 5%,
and efficiencies greater than 92%
(1000W). Each hot-swappable rectifier
has an integral multi-speed cooling fan
and tri-LED status indication.

Controller
The SCU+ and ACU+ (for 2RU systems
only) are powerful control units that enable remote monitoring of the main AC
supply, DC power plant, battery backup
and site environment.
The controller enables advanced battery
management such as sophisticated boost
charge control, remaining capacity test-
ing, constant current discharge testing
and scheduled discharge testing. With
basic energy saving functions, the SCU+
is a cost-efficient system component. For
more sophisticated site monitoring the
ACU+ is available as an option for 2RU
systems only. Information and alarms from
a specific site are monitored or checked
with a web browser or SNMP. When using
SCU+ Controller
a web browser, no additional software
is needed and the web browser login is
password protected.

Distribution
Output distribution for the NetSure™ 211 is available in four different forms. Internal
distribution is attained through GMT fuses or circuit breakers. Internal distribution
options include: (10) GMT fuses (1RU); or 13 GMT fuses composed of a combination
of 15A positions and 10Amp positions; or (4) load circuit breakers (0 to 100A) and
(5) 10A GMT fuses; or (2) load circuit breakers (0 to 100A) and (2) battery disconnect
circuit breakers (0-125A) and (5) 10A GMT positions. All distribution panel options are
available with low-voltage disconnect capability.
Battery Cabinet
Internal Distribution Configuration
An enclosed battery cabinet is available that can be mounted on the wall or in a relay
rack. A 40A battery disconnect is included with the battery cabinet. It can be
connected in parallel with other cabinets to provide additional backup time.
