Precision Uninterruptable Power Supplies where failure is unacceptable

Mitsubishi

Mitsubishi Electric Critical Power Solutions (CPS) designs and manufactures advanced uninterruptible power systems (UPS) that ensure clean, continuous power for data centers, healthcare facilities, industrial plants, and government operations. With a legacy of engineering excellence, Mitsubishi Electric UPS systems are known for high efficiency, exceptional reliability, and long-term performance, protecting critical loads in facilities where uptime is essential.

Mitsubishi Electric’s EVERPOWER brand represents a commitment to delivering reliable, efficient, and future-ready power protection solutions. Within this portfolio, the 1100 Series, 9900 Series, and SUMMIT Series all employ true online double-conversion technology to provide clean, stable power across a wide range of mission-critical applications. The 9900 and SUMMIT models incorporate advanced three-level IGBT topology, delivering superior efficiency for higher-capacity systems. Together, these UPS platforms cover loads from 10 kVA to 2000 kVA, offering both compact, transformerless units and large-scale parallel (N+1) configurations for redundancy and growth.

Select models, including the 9900AEGIS, feature a transformerless UPS design that reduces footprint and improves efficiency. The SUMMIT Series introduces silicon-carbide (SiC) power semiconductors, achieving up to 98 percent operating efficiency and earning ENERGY STAR® certification. These advancements reduce heat output, minimize energy loss, and support sustainability initiatives without compromising reliability.

Mitsubishi Electric’s UPS systems are engineered for longevity, featuring 15-year capacitors and battery options that include both lithium-ion and pure-lead technologies. Combined with customized maintenance bypasses, paralleling cabinets, and dedicated technical support, these design elements simplify service, reduce downtime, and extend system life.

With decades of field experience and a nationwide service network, Mitsubishi Electric CPS supports clients through every stage of the product lifecycle, from design and commissioning to preventive maintenance and performance monitoring. The result is a portfolio of energy-efficient, mission-critical UPS solutions trusted to keep vital operations running without interruption.
