Toshiba has launched the largest unit to date in its line of uninterruptible power supply (UPS) systems for data centers and other mission-critical facilities.

The G9000 data center UPS is an online double-conversion system with 1,000 kVA or 1,000 kW capacity. Energy Star-certified by the U.S. Environmental Protection Agency, the system is 97-percent efficient, according to the vendor.

Units previously included in the G9000 product line featured capacities ranging from 100 to 750 kVA. The entire line is designed for stand-alone or parallel use in configurations up to eight units, without paralleling or load sharing intelligence in the switchgear needed.

The new unit runs at 97-percent efficiency when loaded to 50 percent to 100 percent. Even at 20 percent load, however, its efficiency is 95 percent.

It supports 100 percent unbalanced loads and 100 percent step-load changes without battery discharge. The unit does not need a front-end harmonic filter, producing less than three percent input current total harmonic distortion.
