Mitsubishi 9950A three-phase, on-line double-conversion UPS
Mitsubishi Electric, an industry leader in designing and manufacturing reliable, environmentally friendly uninterruptible power systems (UPSs), announced its 9950A UPS that 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 percent efficiency, the 500kVA UPS supplies clean, continuous power to connected data center and other mission-critical equipment. The 9950A UPS was specifically designed for systems incorporating 380VAC, 400VAC, and 415VAC four-wire installations at 50 or 60 Hz.
The 230/400V 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.
“Our new 9950A UPS will help our customers running mission-critical applications reduce costs, weight and floor space while increasing efficiency,” said Dean Datre, general manager, Mitsubishi Electric Power Products’ UPS division. “More and more data centers – especially those running dense servers - are incorporating the 230/400 volt power distribution scheme in order to take advantage of inherent power efficiencies. Our new 9950A UPS will give these users a dependable power protection solution – reducing total cost of ownership and carbon footprint.”
Mitsubishi’s 9950A UPS can be paralleled with up to eight units for N+1 redundancy. Also featuring an easy-to-use LCD touch panel, users can quickly access system status, monitoring and control.
