NetSure™ ITM with eSure™ Technology
Row-based, Scalable 48V DC UPS
DC Power
For Business-Critical Continuity
™
Efficiency Without Compromise™
provides a path to optimize data center infrastructure
around design, operating and management efficiencies –
while maintaining or improving availability. This is
achieved through the proper selection and utilization of
cooling, power and monitoring technologies, supported
by key services and local expertise.
Features & Benefits
High system efficiency: Reduced power
conversion stages combined with 96%
efficient eSure
(PCUs) and an advanced energy
optimization mode enable significant
energy savings even at low loads.
Scalability and ease of deployment:
Minimize your initial investment and avoid
stranded power by adding expansion DC
UPS modules without interruption in the
field as power needs increase.
DC architecture simplicity: Fewer
components, conversion stages and
distribution breakers throughout the power
chain ensure high availability; elimination of
complex synchronization circuits and the
need to de-rate capacity for phase balancing
or harmonics makes it easy to engineer.
High reliability and exceptional resiliency:
Uninterrupted operation in the unlikely
event of multiple component failures.
Ease of maintenance: Field replaceable,
hot swappable PCUs allow rapid replacement without critical bus disruption; low
voltage allows maintenance without
bypass or shutdown.
Compact footprint: Row-based, integrated
design saves considerable facility space by
eliminating the need for a dedicated power
room and separate PDU distribution.

A Complete Power Protection Solution
The NetSure™ ITM lowers the cost of
data center design, operation and
management. This 48V direct current
solution is a row-based DC UPS that
delivers simple, scalable and highly
efficient power protection.
Rising power density, rapid and unpredictable growth,
escalating energy consumption and cost, plus a myriad of
other power-related challenges are making it increasingly
complicated and expensive to protect critical network
and computing equipment. The NetSure
DC UPS components into a compact, highly reliable
power protection system, offering the answer to your
current and future 48V power needs. This three-phase
480V AC input, 48V DC output UPS provides highly
available power to a wide variety of IT applications and
delivers advanced operating features combined with
reduced total cost of ownership.
™
The NetSure
ITM is designed for deployment directly on
the server room floor, and provides protected 48V power to nearby equipment racks. This
preserves the efficiency and reliability benefits of DC power, while minimizing the amount
of copper required and enabling modular growth.

Unmatched Availability
Central to a data center’s strength is its overall uptime. To maintain business continuity,
power systems must exhibit high availability and easily scale for increasing capacity.
NetSure
UPS. Each DC UPS module includes twelve independent 5.8kW PCUs. These PCUs are globally
renowned with over 2 million units deployed, offering unmatched reliability with less than
0.5% return rate (200 years MTBF). The NetSure
a highly redundant package that minimizes single points of failure.
Proven power conversion topology
Redundant configuration
™
rectifiers or power conversion units (PCUs) are the heart of the NetSure™ ITM DC
Each PCU delivers conditioned,
isolated power to a common
distribution bus
PCUs function in parallel for seamless
redundancy without switching
Units are hot swappable in the field
without system adjustment;
minimum field repair time (MTTR)
increases overall uptime
Redundancy can be achieved both
within a DC UPS module by PCU (N+x),
and by complete system (2N)
Internal power distribution through
(22) branch circuit breakers allows
redundant A+B power paths to each
rack
Battery backup via three parallel
battery strings
Optional dual AC inputs allow
upstream switchgear maintenance
without system outage

Battery monitoring technology from Albér
Detects failing battery cells before
they affect the critical load
Checks each cell and associated
connections via a proactive, patented
resistance test to reliably predict
battery performance
Provides early warning of cell
problems without frequent discharge
tests or battery degradation; minimum technician visits with maximum
run time protection

Lower Total Cost of Ownership
DC power is often associated with
telecommunications where it has
delivered extremely high reliability for
decades. Since DC power is both
provided by backup power sources
and consumed by electronic
equipment, a DC power architecture
minimizes conversion stages from grid
to chip, thus enabling higher overall
efficiency with increased availability.
Factory integrated system for fast and
easy site installation
Service or expansion can be performed
while the DC UPS is in operation,
reducing maintenance costs
Compact footprint with built-in
batteries and distribution, minimizes
required floor space
Designed for scalable growth to
postpone additional capex until
capacity is needed
Energy Optimization Mode
Intelligent Power Matching [Figure 1]
• Achieves near-peak UPS
efficiency down to 5% system
load by optimizing individual
PCU performance, greatly
reducing energy costs over
time in real world conditions
• Matches delivered power
from the UPS to real-time
demand, keeping a minimum
of PCUs active and putting
the rest on standby
• Balances the run time of each
PCU by rotating the active and
standby units
• Maintains the ability to
respond quickly to changing
load conditions

Whatever the physical layout of your data center,
the NetSure
™
ITM minimizes required floor space. With DC UPS
building block modules, you can mix and match configurations
and standard layouts to fit your available space.
Flexibility to Meet the Needs of Any Data Center
The NetSure™ ITM solution is a modular system in 70 kW increments,
expandable up to 280 kW (4 DC UPS modules) with one controller.
Flexible Capacity
Each integrated DC UPS module occupies
only 24" (W) x 41" (D) of floor space,
including batteries and primary distribution
Delivered fully configured for quick and
easy field installation
Typically installed in either the middle or at
the end of a row of server racks
Deploy only the capacity that is initially
needed; DC UPS modules can be added at
any time to row configurations on the data
center floor
Choose from top and bottom cabled
variants for installation in either concrete
or raised floor environments
™
As Figure 2 illustrates, the NetSure
solution starts with a primary DC UPS
module rated for 70kW. As your power
needs increase, you can add up to three
expansion DC UPS modules, for a maximum
capacity of 280kW that may be configured
for N+1 redundancy by subtracting one 6kW
PCU from the rating. Each DC UPS module
also includes 48V primary power distribution
with 22 circuit breakers (6 fuses optional).
Various server rack densities are supported
with 5-10 minutes of battery backup time
across three parallel 48V battery strings.
ITM
Figure 3 depicts two top-cable installation
scenarios. Depending on your site and
budget requirements, the NetSure
solution can either be installed as a single
deployment [Figure 3a], or incrementally by
row [Figure 3b] as power requirements grow.
In either scenario, DC distribution cabling to
each rack is reduced by placing the NetSure
ITM in-the-row.
