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.
