GE SG Series 10 - 750kVA

The SG Series UPS includes the outstanding performance characteristics such as front access, internal 5th & 11th harmonic filter, and fused surge protection are just a few of the design features that make the SG Series UPS best in class for output performance, footprint, efficiency and functionality.

The SG Series UPS is one of the best performing and most reliable three-phase UPS systems, providing critical power protection for a wide range of mission critical applications. Every UPS system operates in double conversion mode with true continuous on-line VFI (voltage and frequency independent) operation, yielding the maximum levels of power reliability for all mission-critical applications.  The SG Series UPS was developed using GE's Design for Six Sigma methodology to ensure that the product fully meets customer requirements and expectations.

To achieve N+1 redundancy or to increase power capacity, the SG Series UPS can parallel up to eight (8) units (10-750kVA) using GE's unique Redundant Parallel Architecture (RPA) technology in a flexible and cost effective manner.  In the RPA system, every UPS is controlled in a true peer-to-peer configuration with redundancy in all critical elements and functions.  This advanced technology provides the highest possible system reliability eliminating any single points of failure associated with other types of UPS systems.  The RPA system precisely synchronizes the output phase and automatically shares the load supported by each of the UPS.

Features and Benefits

  • Space Vector Modulation (SVM): an advanced Pulse Width Modulation (PWM) digital control technique, to modulate the inverter resulting in fast transient response, and high efficiency
  • Redundant Parallel Architecture (RPA): With RPA, SG Series UPS are controlled in a true peer-to-peer configuration, where all critical elements and functions are redundant
  • Digital Signal Processing (DSP): High speed DSP allows for extensive event logging capabilities and improves UPS response time and stability of installed parameters
  • Superior Battery Management (SBM): Enhances battery life and dramatically increases system reliability with online and programmable battery testing features
  • Standard inverter output isolation transformer that isolates utility power from the load providing additional critical power protection.
  • Efficient output across the load range with best in class part load efficiency up to 94.4%  in online mode.
  • Compact footprint, front access design, and internal maintenance bypass decrease installation, maintenance, and repair costs driving reduced Mean Time to Repair (MTTR).
  • Faster transient response for non-linear and 100% step loads.

Services | Powerwave Energy Solutions

If your UPS is in alarm condition and your data center is vulnerable we suggest you call us immediately whether you are currently a customer or not - regardless of make and model. Most of them came to us because they were fed up with slow response, lack of technical competence and generally poor customer service. Buying a maintenance agreement for your UPS is similar to buying an insurance policy for your home or business.
