Uninterruptible power system
Finalist in Emergency, On-site, Standby Power in Consulting-Specifying Engineer's 2011 Product of the Year competition
The 9900B Series UPS System from Mitsubishi Electric Power Products, Inc. delivers a power rating of 750 kVA and maximum efficiency of more than 96%. To achieve increased capacity or redundancy, the product can be configured in a parallel system of up to eight units. The modular system architecture saves on floor space by providing the option of adding or removing modules. The products have a 30% smaller footprint than typical UPS modules with a similar power rating. The system includes insulated-gate bipolar transistor (IGBT) technology controlled by the Mitsubishi Digital Signal Processor and direct digital control (DDC).
