The industry’s best combination of efficiency, management of THD, power factor, and power protection

With the introduction of the Powerware 9390, you

can now enjoy an unmatched combination of power

protection features in a single system. The new three-

phase UPS is the result of comprehensive research

and user insight gathered by Eaton to develop the

best combination of power performance, battery

management, scalable architecture, flexibility, and

service.

The Powerware 9390 UPS
features innovations that
combine to deliver the
industry’s best overall
power performance. Built
on more than 40 years of
UPS design expertise, the
Powerware 9390 excels in
four key factors:
1. Efficiency - maximum
usable output power
relative to input power
2. Total harmonic distortion
(THD) - keeping input
current distortion within
acceptable limits
3. Power factor - managing
phase shifts between
voltage applied and
current drawn by circuits
4. Double-conversion
topology - complete
isolation of protected
loads from input utility
power
produces cooler operating
conditions within the UPS,
which extends the life of
components and increases
overall reliability and
performance.
Low THD enhances
compatibility with
generators
The Powerware 9390 uses
a new input circuit that is
uniquely capable of keeping
Total Harmonic Distortion
(THD) at a low level—less
than 5 per cent—without
compromising efficiency. A
key benefit is that the UPS
is therefore compatible with
a wide range of generators,
even though generator
output frequencies will
fluctuate when the UPS
transitions to generator
power and as other loads
are started up.
Power factor
performance maximises
compatibility and meets
high power factor load
requirements
The closer the power
factor is to unity, the more
efficient the transfer of
power between source
and load. With an input
power factor of 0.99, the
Powerware 9390 UPS is
exceptionally compatible
with diverse power sources,
especially auxiliary
generators.
On the output side, the 9390
can also provide its full
power capability to loads
that have a wide range of
leading and lagging power
factors, spanning all known
computer loads.
Double-conversion
topology provides the
best protection possible
With the Powerware
9390’s double-conversion
process, your sensitive
electronic systems are
completely isolated from
raw utility power and all
its irregularities. Double
conversion provides
the highest level of
protection available and
enables equipment to
perform to manufacturer
specifications.
Whether you are selecting
a UPS for a branch office,
manufacturing floor,
medical facility, or a large
data centre, there is a
Powerware 9390 model
that delivers just the right
combination of performance
and price for your needs.

High efficiency
reduces overall cost of
ownership
The efficiency rating of a
UPS is a measure of the
energy the UPS uses for
its own operation and
dissipates usually in the
form of heat. For example,
a UPS that is 90 per cent
efficient delivers 90 kW of
useful output power for
every 100 kW it takes in.
The more efficient the UPS,
the less you pay to run your
protected equipment and to
cool the UPS.
With a transformerless
design and sophisticated
sensing and control
circuitry, the Powerware
9390 UPS delivers an
efficiency of up to 94 per
cent. In addition to dramatic
cost savings, this level of
system efficiency extends
battery run times and
