User Manual
SG Series 225 & 300 UL S2
3 INTRODUCTION
An
Uninterruptible Power Supply
(UPS) provides the power for critical loads that need a reliable,
continuous, disturbance free supply.
In case the power provided by the
Utility
fails, or exceeds the permitted tolerances, the power to supply
the
Load
is provided by the
Battery
for the specified time at the rated
Load
(or longer at a reduced
Load
)
or until the
Utility
power returns.
SG Series 225 & 300
is a true double conversion
VFI
(Voltage Frequency Independent)
UPS system where
the
Load
is continuously supplied by the
Inverter
through the
Rectifier
.
In case of trouble on the
Inverter Output Voltage
, or when overload or short-circuit on the output occur,
the
Load
is instantly transferred to the
Utility
via the
Automatic Bypass
.
The UPS automatically returns to normal mode when the failure condition is restored.
Key features
:
•
More Critical equipment supported
Rated at 0.9 Power Factor,
SG Series 225 & 300
delivers more real power than other UPS in the
market.
With today’s trend toward power factor corrected loads,
SG Series 225 & 300
can support more
total
Load
than any other UPS available, allowing you to support a greater number of today’s
enterprise computing Power Factor Corrected (PFC) equipment.
•
No single point of failure
Redundant Parallel Architecture (RPA) is an exclusive
GE
technology.
With RPA,
SG Series 225 & 300
UPS are controlled in a true peer-to-peer configuration where all
critical elements and functions (including
Bypass
) are redundant.
SG Series 225 & 300
is designed to be the most reliable power protection system available on the
market today.
•
High Efficiency
Using IGBT technology and Space Vector Modulation (SVM) strategy,
SG Series 225 & 300
offers low
output voltage distortion and provides efficiencies up to 93%.
•
Fully digital
Digital Signal Processor (DSP), Flash memory and SVM strategy, are the technology corner stones
of new age of power quality and power reliability.
•
Extremely flexible
Tailor made power protection to meet your individual installation requirements;
SG Series 225 &
300
offers various options like input harmonic filters and our comprehensive
GE Power Diagnostic
software suite for mission control and data protection to cover all your application needs.
