The 9950A UPS provides mission-critical operations with an efficient UPS design for 400 Volt power distribution infrastructures. Widely adopted in Europe and Asia, the 230/400 volt power distribution approach has gained traction in high-density data centers in North America due to significant increases in energy efficiencies – reducing a facility’s operating costs and carbon footprint.
Like all other Mitsubishi UPSs, the new 9950A is a three-phase, on-line double-conversion system and features Mitsubishi’s world-renown Insulated Gate Bipolar Transistor (IGBT) technology for enhanced UPS performance and reliably. Offering over 96% efficiency, the 500 kVA UPS supplies clean, continuous power to connected data center and other mission-critical equipment. The 9950A UPS was specifically designed for systems incorporating 380 VAC, 400 VAC, and 415 VAC four-wire installations at 50 or 60 Hz.
The 230/400 V electrical distribution infrastructure eliminates the need for expensive, heavy transformers and extra circuit breakers required for 120/208V power distribution. The higher 230/400V power scheme has additional advantages such as eliminating possible failure points (circuit breakers), occupying less overall floor space (no transformers required), and increasing efficiency through increased power delivery.
