UPS Series expansion
Mitsubishi Electric, a manufacturer of uninterruptible power supplies (UPS), announces a significant extension to their already successful 9900 Series UPS in three new sizes: 1.4, 1.75, and 2.1 MVA. Like all other Mitsubishi Electric UPS products, these new units are all three-phase, online double-conversion systems and feature insulated gate bipolar transistor (IGBT) technology for improved performance and the reliability. The advanced three-level topology utilized in the 9900 Series enables efficiencies of up to 97% while operating in an online double-conversion mode. These new sizes utilize a modular design and are upgradeable in the field, allowing customers to upgrade UPS capacity over time as warranted by changes in their load requirements.
