  1. Power QualityProduct Overview GE Consumer & Industrial

  2. Content • Introduction • UPS Products • Static Transfer Switches • GE’s unique technologies

  3. Energy is the Key The actual power grid was built to supply the 3 main inventions of the last Century: the light bulb the electric motor the refrigerator Utilities provide a reliability of 99,9%= 8 hours out of tolerance/year„good enough“ for this type of application To produce, store, transfer and restore 4 MB of data we „burn“ the energy equivalent of 1 Kilo of coal

  4. = Utility not meeting business requirements Process Fact: 99.9% Need: 99,9999999..% „DIGITAL WORLD“ ELECTRICAL POWER CRITICAL RAW MATERIAL OF THE 21ST CENTURY: QUANTITY & QUALITY & RELIABILITY OF ELECTRONS

  6. Key Products – GE C&I • UPS Uninterruptible Power Supply • Active Filters • Static Transfer Switches • Protecting equipment and processes against disturbances in the utility • Eliminating higher harmonic currents, mains cleaning • Automatic switches to increase reliability of supply • to loads

  7. UPS – Product Range 0.35 – 3 KVA 3 to 30 KVA Single or Redundant 20 – 120 KVA Single or Redundant – 4’000 KVA Redundant Commercial Telecom - Wireless Telecom - Wireline Small Enterprise – Data Centre Medium Enterprise – Data Centre Large Enterprise – Data Centre External Data Centre Semiconductor Fab Process Industry BioTech, Pharmaceuticals, Hospitals

  8. Single Phase output UPS Typical Application ML Series • 350 - 1000VA (Sourced) • Entry level product range • Line interactive pluggable • Single PC • EPOS • CCTV cameras Match • 500 - 3000VA • Mid level line interactive pluggable • High reliability and performance • Small server • Hubs, routers NetPro • Servers and PCs • Small IT networks • Telecom networks • Process control • 600 - 4000VA • Double conversion pluggable • Mature technology, replacement 2006 LP Series • 3 - 10kVA LP11/31T • 8 - 20kVA LP31 • Double conversion installable • Unique RPA • Mid-range IT networks • Healthcare equipment • Process control • Large telecom networks

  9. Three Phase output UPS LP33 Series Typical Application • Healthcare equipment • IT infrastructure • Telecom networks • 10 - 120kVA • Transformerless; Clean Input Tech • Small footprint, front access SitePro • Process control • Transportation infrastructure • Telecom networks • Healthcare equipment • 10 - 60kVA ; 250 - 500kVA • Transformer base design • Configurable according to installation requirements SG Series • 80 - 200kVA • Best in class in output performance • EMC solution for critical applications • IT networks • Industrial applications • Broadcasting systems

  10. PRIMARY SOURCE SECONDARY SOURCE K4 K5 normally ON normally ON O1 O2 L1 L2 U1 U2 O3 CT1 K1 K3 K2 normally OFF normally ON normally OFF STS OUTPUT Static Transfer Switches • STS Static Transfer Switch • Electronic switch that ensures uninterruptible switching between a preferred source and an alternate source. (primary or secondary) • Automatic operation – in case the preferred source is out of limits (fails) the load is automatically transferred to the healthy alternate source. • This transfer is seamless in case both sources are synchronized

  11. Static Transfer Switches • Redundant power supplies • Redundant cooling • Over voltage protection • Front access for service • Manual bypass • Alarm contact interface • User friendly control panel • Neutral dimensioned for 200% • Unique conductivity detection 3 phase STS: 25 – 630 A 400V 3&4 pole 1 phase STS: 25 – 400 A 230V 1&2 pole

  12. GE‘s unique technologies RPA Redundant Parallel Architecture High reliability UPS cluster with no single point of failure SEM Super ECO Mode Saving energy whilst maintaining high protection level IEM Intelligent Energy Management Award winning concept for energy savings

  13. Redundant Parallel Architecture utility supply • Up to 8 units in parallel • Any UPS able to be the logic leader • Decentralized bypass • Redundant Communication Bus • Transparent failover and recovery process • True redundancy with no single point of failure to critical load

  14. Super ECO Mode SS DC AC DC AC VFI concept 2 Conversion Processes: + optimal protection for mission critical applications - increased energy losses Balance: For less critical loads run UPS on bypass continuously In case mains is out of limits transfer the load to inverter Super ECO Mode: not only is the load supplied on bypass, but the inverter is also switched off, increasing energy savings

  15. Super ECO Mode < 2ms Bypass on/off Output voltage Inverter current Inverter control Fast Transfer to Inverter • Super ECO mode • Efficiency : 98% • to Inverter in case Bypass is out of limits • Fast error detection • Extremely short transfer times (<2 ms) • User definable scheduling • Available for 10 – 500 kVA

  16. Intelligent Energy Management UPS: Cost of Ownership • Purchasing Cost & Installation Cost • Direct Operating Cost Efficiency = Energy Losses = Heat • Indirect Operating Cost Heat = air conditioning / Ventilation • Maintenance Cost
