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 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 0.8 Power Factor for SG Series 400 kVA and at 0.9 Power Factor for SG Series 500 kVA, SG
Series delivers more real power than other UPS in the market.
With today's trend toward power factor corrected loads, SG Series 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 UPS are controlled in a true peer-to-peer configuration where all critical
elements and functions (including Bypass) are redundant.
SG Series 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 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 offers
various options like input harmonic filters and our comprehensive JUMP software suite for mission
control and data protection to cover all your application needs.
