Mitsubishi introduces 400V UPS for high-density data centres
By Alyssa Dalton
February 13, 2014 – Mitsubishi Electric has announced its 9950A uninterruptible power supply (UPS) for mission-critical operations and 400V power distribution infrastructures.
The unit is a three-phase, on-line double-conversion system and features Mitsubishi’s Insulated Gate Bipolar Transistor (IGBT) technology boasting enhanced UPS performance and reliably. Promising more than 96% efficiency, it is specifically designed for systems incorporating 380vAC, 400vAC and 415vAC four-wire installations at 50Hz or 60Hz. According to the company, its 230/400V power scheme eliminates possible failure points (circuit breakers), occupies less overall floor space (no transformers required), and increases efficiency through increased power delivery.
