Static Transfer Switches PRIMARY SOURCE SECONDARY SOURCE K 4 normally ON K 5 normally ON O 1 • Electronic switch that ensures uninterruptible switching between a preferred source and an alternate source. (primary or secondary) O 2 L 1 L 2 U 1 U 2 O 3 CT 1 K 1 normally OFF K 3 normally ON STS OUTPUT STS Static Transfer Switch K 2 normally OFF • 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 10 / GE / July 2006

Static Transfer Switches • Redundant power supplies • Redundant cooling • Over voltage protection • Front access for service • Manual bypass • Alarm contact interface • User friendly control panel 3 phase STS: 25 – 630 A 400 V 3&4 pole 1 phase STS: 25 – 400 A 230 V 1&2 pole • Neutral dimensioned for 200% • Unique conductivity detection 11 / GE / July 2006

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 12 / GE / July 2006

Redundant Parallel Architecture utility supply to critical load • 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 13 / GE / July 2006

Super ECO Mode SS DC AC VFI concept 2 Conversion Processes: Balance: + optimal protection for mission critical applications - increased energy losses 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 14 / GE / July 2006

Super ECO Mode Output voltage Bypass on/off < 2 ms Inverter current Inverter control 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 k.
