Toshiba G9000 Series UPS is available in capacities of 100, 160, 225, 300, 500, 750, 1000, 1330, 1500, 1600, and 2000kVA and comes with an industry-leading three-year onsite warranty. It is designed for stand-alone or parallel use in up to eight-unit configurations (100-1000kVA) or six-unit configurations (1330-2000kVA) without requiring the use of a special switchgear cabinet. Using the new Toshiba IGBT technology in the rectifier/converter, DC/DC chopper, and the inverter sections of the UPS, the G9000's double-conversion topology provides an AC/DC/AC efficiencies of up to 97% at loads from 50% to 100%. Even at 20% loading, the efficiency remains greater than 94%. This is 10% to 20% better than current industry systems, making the G9000 excellent for N+1 parallel systems where loads are typically 30-40%.
