9900B Three Phase UPS

The Best Selling UPS in its range

9900B 750 kVA UPS

480V / 300, 500, and 750 kVA

Like all other Mitsubishi Electric UPSs, the 9900B is a three-phase, on-line double-conversion system and features Mitsubishi Electric's world-renown Insulated Gate Bipolar Transistor (IGBT) technology for enhanced UPS performance and reliability. It enjoys the largest install base, with just under 2000 in North America alone. The 9900B is available in 300, 500, and 750 kVA, and is Energy Star rated.

Features

Reliability

If downtime in your business equals disaster, Mitsubishi Electric delivers the highest reliability among backup power equipment suppliers through robust proprietary technology designed to deliver continuous power in the most demanding environments. Whereas competitors only estimate their reliability, Mitsubishi Electric’s installed base of 9900 series Uninterruptible Power Supplies have sustained load carrying capability more than 99.9992% of their actual operational history.

Control

How an IGBT power device is controlled is key to achieving optimum performance characteristics of a UPS. Utilizing a combination of high sampling rates and Direct Digital Control (DDC), the 9900B is able to provide superior performance under all load conditions.

Benefits to the customer include excellent output voltage control, dynamic inverter response, and minimal voltage distortion during full load steps without the DC source. These characteristics maximize the performance of the UPS and increase the overall reliability of components and the system.

 

Superior Control

Footprint Comparison

All the Power. Smaller Footprint.  

The 9900B Series UPS creates more white space by minimizing the gray space it occupies. It can handle the same load in a significantly smaller footprint than competitive models, meaning more space can be allocated o revenue generation. The 9900B also has higher power density than comparable UPSs, maximizing power output while minimizing gray space.

Efficiency

As UPS systems are often viewed as one of the biggest culprits regarding energy loss in power distribution, it makes sense to consider efficiency, along with reliability, as a primary factor in the selection of a UPS. 

Through its history of technological developments, Mitsubishi Electric has proven to be a leader in advancing efficiencies to unprecedented levels.  Beginning with the use of IGBTs for converters and inverters and 3 level topology and followed by the promotion of transformerless designs, Mitsubishi Electric has long been at the forefront of offering Uninterruptible Power Supplies with the highest efficiencies available coupled with unparalleled reliability.  Mitsubishi Electric's superior expertise in optimizing power device control is evident by the flatness of the resulting curve, demonstrating high efficiency across all load levels.  Please note that all efficiency curves published on this site are for the respective UPS operating in true online double conversion (aka VFI).
