see options table for individual
models
• Isolation transformers
• Second outlet emergency only
CHARACTERISTICS
• Full microprocessor control:
for greater reliability and compactness
in size
• Use of Isolated Gate Bipolar
Transistors (IGBT) technology – used
in UPS for over 10 years to optimise
performance (such as overloads) and
reduce physical sizes

service compatible for remote
diagnostics and control
• Front panel LCD to display operating
status, alarms, measurements and
logs
• Option to expand the power and/or
reliability through the parallel
connection of units – 8kVA models
and higher
ADVANCED COMMUNICATION
• Advanced, multi-platform
communication for all operating
systems and network environments:
Watch&save 3000 monitoring and
shut-down software included, for
Windws 2008, Vista, 2003, XP; Mac
OS X, Linux, Novell and most popular
Unix operating systems.
EXAMPLE OF CSS CONFIGURATIONS
A FULL RANGE OF CSS UNITS,
FROM 700VA TO 200KVA.
The CSS range units are
comprised of the following blocks:
Rectifier: converts the
alternating voltage input from
the mains power supply or from an
alternative source (generator) into direct
current voltage.
Inverter: converts the direct
current voltage supplied by the
rectifier into alternating voltage. In this
way the voltage is reconstructed,
filtered and stabilised with regard to the
input voltage.
By-pass: this allows switching
between the inverter and the
mains power supply. In “always
powered” operating mode the CSS
load is always powered from the
inverter and is only switched onto the
mains via the by-pass circuit in the
event of a failure. In “powered from the
mains” mode, the load is powered and
only switched onto the inverter when
there is no power from the mains. In
“emergency only” mode the load is only
powered from the inverter in the event
of a mains power failure. To deal with
the current surges required by the
powered loads at switching-on time, a
Soft Start inverter has been
implemented in order to limit the value
of current required. In “always
powered/emergency only” two outputs
can be used: one always powered
(such as for powering computer loads)
and one that is only powered when
there is no power from the mains (such
as for powering emergency lights that
by law must switch on within a
maximum time of 0.5 seconds from a
mains failure).
Batteries: used to feed the
inverter output for the legally
required time of 3 hours (if there is no
generator). The batteries used are
generally valve-regulated, lead-acid
type, and do not require maintenance
or a special installation room as they
have very low gas emissions.
Compliance with Legislation
The CSS configurations complies with
the relevant European regulations (and
national guidelines still in force in some
countries) governing such applications.
