The IGBT power device for the 9900B UPS achieves superior function under all load conditions.
Benefits to the customer include -
These characteristics maximize the performance of the UPS and increase the overall reliability of components and the system.
Designed with not only reliability, but also maintenance in mind, the various system components of the 9900B UPS minimize or help ease system maintenance. Low-effort accessible upkeep systems ensure consistent quality operation for the lifetime of the system. Below are just a features that make the 9900B easy to maintain:
With these specifically designed features, mean-time-to-repair, including any replacement of components, does not exceed four hours.
There's a good reason the 9900B is preferred by our customers in the financial, medical, and cloud computing sectors: It's a workhorse with stellar performance rating across markets.
Data Centers
Edge Data Centers
Cloud Computing & Colocation
Financial Sector
Hospital & Healthcare
Enterprise data centers supporting financial firms employ the 9900B, helping them deliver excellent customer service essential to maintaining a loyal customer base. Hospital and healthcare providers demand readily accessible and transmittable patient information. They choose Mitsubishi Electric UPS for their data centers because they are committed to ensuring their critical power infrastructures are the gold standard of reliability.
Regional edge data centers in non-major cities of the Tier II and Tier III levels, such as Birmingham and St. Louis, leverage the 9900B to deliver backup power in remote installations. These edge data centers process data as close to the end user as possible, thereby reducing latency issues common to larger, but more distant, data centers. They require a UPS with sufficient power and a small footprint.
Medical institutions deploy the 9900B to protect the critical power systems that fuel urgent care. Our UPS ensures essential equipment is dependable and expensive procedures are successfully performed without interruption or damage.
These are just a few of the markets where the power, size, efficiency, and reliability of the 9900B makes it the best UPS for the job. Contact us today to see how we can support your mission critical power needs with a 300kVA, 500kVA or 750kVA UPS from Mitsubishi Electric.

While individual unit efficiency can fluctuate slightly under various operating conditions, Mitsubishi Electric is so confident in the efficiency of our product when optimally installed onsite, that we offer a performance guarantee.
When installed, the AC/AC efficiency of the 9900B UPS will not be <1% below the efficiency published in our factory specifications. This will be verified by a performance test - either at our factory or an acceptable test site - with a module operating on inverter and the battery disconnected.
In the event the 9900B fails to comply with this guarantee in a verified performance test, Mitsubishi Electric will refund the purchaser an amount up to a maximum $10,000 per year for three years.
Please note that all efficiency curves published on this site are for the respective UPS operating in true online double conversion (aka VFI).
Mitsubishi Electric offers various DC power solutions with both lithium ion and VRLA battery cabinets, which you can learn more about below. With respect to lifespan and operation efficiency, new lithium ion batteries now outlast traditional VRLAs. They're also getting smaller, with the new BCL04-BB cabinets being the perfect size to support applications that require a small footprint.
