Mitsubishi 9900D 1500 kVA (#10716)

Mitsubishi Electric 9900D Series 1500 kVA

The Mitsubishi Electric 9900D Series is a high-capacity, modular, three-phase Uninterruptible Power Supply (UPS) system designed to deliver industry-leading reliability, efficiency and serviceability for mission-critical environments. With ratings available from 1200 kVA up to 2000 kVA, this system is built for large data centers, industrial operations, and infrastructure applications demanding uninterrupted power protection.

At the core of the 9900D’s performance is its online double-conversion topology and advanced IGBT three-level power modules, which deliver up to 97% AC-to-AC efficiency even at low load levels.

The unit’s modular architecture supports N or N+1 redundancy and enables expansion in fixed-increment modules, allowing customers to pay for the capacity they need today while retaining future scalability.

In operation, the 9900D has a demonstrated sustained load-carrying capability of 99.9995% across its installed base, a testament to its robust design and field reliability.

The series also stands out for its compact footprint, high power density and flexibility. For example, the 2000 kVA version achieves a significantly reduced spatial requirement compared with equivalent competitive units—helping reduce “grey space” and increase valuable revenue-generating floor area.

Support for multiple battery technologies, including VRLA, flooded cell, nickel-cadmium and lithium-ion—adds to the 9900D’s adaptability across diverse deployment scenarios.

In sum, the Mitsubishi Electric 9900D Series is engineered to deliver the highest levels of power integrity, flexible capacity growth, and operational efficiency. For power-protected facilities that cannot compromise uptime, it offers a future-proof investment backed by Mitsubishi’s service network and product heritage.

The 1500 kVA variant of the 9900D Series gives you a full-scale power protection solution built for demanding commercial, industrial and data center environments. With true on-line double conversion, the unit operates at up to 97% efficiency while delivering clean, conditioned power and shielding connected loads from brown-outs, voltage sags, line noise and grid disturbances.

Modular modules support incremental expansion (e.g., in 350-kVA increments) and N+1 redundancy, enabling your installation to grow with your business while maintaining high availability.

Engineered for serviceability and flexibility, this model is compatible with multiple battery chemistries and offers self-load test capability, eliminating the need for external load banks during commissioning or maintenance.

Whether you’re protecting a high-density data center, an industrial process facility or critical infrastructure, the 1500 kVA 9900D gives you Mitsubishi’s proven design, high performance and the capability to deliver uninterrupted power and scalable capacity, today and into the future.
