The Regional DC power
system with Global Muscle
ACTURA® 4855
-48 V DC, 3-40 kW, 60-800 A
Reliability or Price Efficiency?
Now you can have both!
Customized power systems with high reliability
– at a competitive price – is an argument that has
existed as long as power systems. Both bring undisputable advantages. Emerson is now introducing
a new generation of power systems offering the best
of both worlds, thanks to a new approach not only to
the product, but also to design, production, system
verification and the logistics set-up.
Fast customization
Emerson’s new power system ACTURA® 4855
is based on a concept with modular building
blocks designed to meet present and future
capacity and functionality needs. The concept
allows the regional configuration center to
“put together” an almost unlimited number
of configurations, easily and quickly, to fulfill
your new needs or site-specific requirements.
As your business grows, ACTURA® 4855 also
permits easy capacity extensions or functionality
upgrades during live operation.

Electronics benefit from volume –
both in terms of reliability and price
Electronic systems like rectifiers and controllers benefit from substantial initial design and
production investment. Additional design
loops, rigorous design verification, automated
assembly and final testing – all result in better
products with higher and less varying quality.
To achieve this – at a competitive unit cost
– large-volume production is required.
DC power for small to medium
size applications in wireless
and wireline networks.
Global building blocks To achieve the highest
possible volumes, Emerson decided that all
new rectifiers and controllers should be used
globally. These building blocks are based on
telecom requirements and design specifications from Emerson’s regional design
centers all around the world. This strategic
decision has now resulted in centralized
manufacturing of many thousands of global
building blocks per month. After thorough
testing, the building blocks are shipped to
regional configuration centers, where they
are integrated into different regional systems.
Price efficient mechanics complying with
regional telecom standards and norms
The requirements and preferences for the nonelectronics part of a power system, such as
the rack/cabinet and distribution, vary greatly
in different parts of the world. The footprint,
EMC shielding, earthquake sustainability and
cabling routes are some of the variables.
Circuit breaker configurations are also sitespecific in many cases. Since most volume
advantages for electronics do not apply to
mechanics, the mechanical portions of power
systems are best designed and produced and
tested close to the markets and customers
they will serve.
Local support – globally
Emerson’s building-block based design,
manufacturing and logistics strategy combines
local adaptability of the mechanics with
unsurpassed volumes of rectifiers and controllers
for ACTURA® 4855. But our goal to customize our
offering for your needs does not stop there.
Whenever you need support for any of our
products or their applications, we are always close
by through our local companies and partners all
around the world.
That’s why Emerson Network Power’s new AC
& DC distribution units, battery connection
units, racks and cabinets are manufactured as
regional building blocks in the region where
they comply with local telecom standards.

Since the building blocks have been
designed and verified according to
both global and regional telecom
standards and norms the new system
configuration immediately complies
with the regional telecom standards
and norms.
The ACTURA® 4855 uses the same building blocks for
a wide power range; 3-40 kW. This enables you to save
time and money - through more efficient purchasing,
logistics set-up, spare parts management, and
maintenance service routines.

and Maintenance
Monitoring
The smart controllers and supervision
modules, used by ACTURA® 4855, were
designed and developed for global use
to monitor and control DC power system
and telecom site equipment.
The two global controllers with different
monitoring functionality are called SCU
and ACU.
The SCU provides detailed information
about the DC power systems functions
and alarms by means of a graphical
Display on site, or through a web browser.
The ACU can, together with different
supervision modules, collect and
present detailed information and alarms
related to AC mains, diesel gensets,
battery backup, fans, fire detection
systems, doors, and other auxiliary
equipment by means of digital/analog
inputs/outputs and relays.
The controllers are hot swappable, and
permits you to easily upgrade the
Monitoring functionality when needed.
The units can be inserted either in the
rectifier rack or in the Multi Function Units.
