Uninterruptible power system
Finalist in Emergency, On-site, Standby Power in Consulting-Specifying Engineer's 2011 Product of the Year competition
Toshiba’s G9000 uninterruptible power systems are designed for stand-alone or parallel use in up to eight-unit configurations, without requiring a special switchgear cabinet. The double-conversion topology provides an ac/dc/ac efficiency of 97% at loads from 50% to 100%. The insulated-gate bipolar transistor (IGBT) design eliminates the need for a front-end harmonic filter and produces less than 3% input current total harmonic distortion. The product does not need an output transformer, thus improving efficiency and reducing weight, noise, and total footprint. It supports 100% unbalanced loads and 100% step-load changes without battery discharge.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
