Toshiba International Corp. announced plans to release its G9000 400V uninterruptible power system (UPS) in 500 kVA/450 kW capacity. It will be available in the summer of 2013.

The G9000 Series offers online, double-conversion systems with up to 97% efficiency, the vendor said. This is the first model in a new series of G9000s Toshiba is bringing to international markets.

The Toshiba G9000 UPS line is purpose-built for data centers and call centers. The 400V model range is designed for use with 380V, 400V and 415 four-wire installations, at 50 or 60 Hz.

Multiple configuration options make the units suitable for markets throughout South America, Europe, the Middle East and Asia, as well as domestic installations using transformerless configurations that require a neutral. They are designed for stand-alone or for parallel use with up to eight units, without requiring paralleling or load-sharing intelligence in the switchgear cabinet.

Using Toshiba IGBT technology in the rectifier/converter, DC/DC chopper, and inverter sections, the 400V model double-conversion topology provides an AC/DC/AC efficiency of over 95% at loads from 50% to 100%. At 25% load, the efficiency remains greater than 94%.

The efficiency makes it a good solution for redundant parallel systems where loads are typically 30% to 40%. The all-IGBT design also eliminates the need for a front-end harmonic filter and produces less than 3% input current total harmonic distortion.

The 400V 500kVA model offers an input power factor greater than 0.99, a wide-input voltage range of 15% to -20% and an output power factor rated at .9. They support 100% unbalanced loads and 100% step-load changes without battery discharge, and are equipped to support monitoring adapters utilizing SNMP, MODBUS and other protocols.

The units come with Toshiba's three-year onsite warranty.
