Without reliable power quality resources, thousands of dollars are lost per minute in direct costs such as damaged components and equipment, extra maintenance costs, failed component replacement costs, liability for health/safety, and loss of revenue due to downtime. You will never be more aware of the value of your power quality products than when they simply function properly and protect your company’s productivity. When failure is not an option, Reliabl is the power quality resource prepared to maximize your uptime with a variety of products.


480V / 500 & 750 kVA

The next-generation power semiconductor is here! In the SUMMIT Series® UPS, the Si (silicon) IGBT is replaced with advanced capability SiC (Silicon Carbide) semiconductors. The IEEE states that silicon carbide is to the 21st century what silicon was to the 20th century. Mitsubishi Electric began development of SiC semiconductors during the early 1990’s and now offers this proven technology in the SUMMIT UPS. Higher efficiencies are achieved across all load levels with SiC’s lower switching losses, higher switching frequencies, and improved thermal conductivity range

208V / 6, 8, 10, & 12 kVA Single phase UPS Systems

The 7011B single phase UPS from Mitsubishi Electric is a true online, double conversion single phase power supply that will protect your equipment from disruptions in power, such as brown-outs, line noise, voltage transients, and power outages.

Single phase power systems serve as an ideal backup solution for individual computers, small networks, communications systems, security systems, and point of sale systems. The 7011B is simple to start up, operate, and maintain. It includes internal batteries with the option of adding external battery cabinets for longer runtimes.


The DiamondPlus® 1100 Series

Need a server room or IT backup UPS?

The DiamondPlus® 1100 Series Uninterruptible Power Supplies from Mitsubishi Electric provide quality and reliability in a smaller footprint. Our modular UPS is compact, but designed with room to expand. A perfect server room UPS, it can also provide backup power to network closets and control rooms, as well as being utilized in edge data centers.

When you have lower backup power requirements, there’s no reason to invest in more than a 10-80 kVA UPS – giving you just the right amount of power, with room to grow as needed. Mitsubishi Electric’s 1100 Series provide high-performance power protection for lower but still critical loads. Hot swappable UPS power modules provide redundancy and maximum flexibility for expansion as well as rapid maintenance and repair.

Three-phase, on-line double-conversion system and features Mitsubishi Electric’s world-renowned 3 Level Insulated Gate Bipolar Transistor (IGBT) technology for enhanced UPS performance and reliability. The AEGIS™ series is available in 80, 100, 150, 160, and 225 kVA and is UL924 listed (Standard for Emergency Lighting). One of the outstanding features of the AEGIS™ is that it boasts a relatively flat efficiency curve indicating that the UPS is highly efficient regardless of the load. This is significant since loads in various data centers can range anywhere from 25% to nearly 100%. The AEGIS™ can be configured both as a single module or in multi-module systems up to 4 units.

UPS 9900B 480V 300-750KVA

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.

As the best-selling UPS in the 500-800 kVA range, the 9900B Series UPS delivers all-around dependability:

  • 97% efficiency in double conversion
  • Ease of maintenance via front access to pull-out trays
  • Low heat rejection
    Industrial fans
  • Distributed bypass design for multimodule operation

Providing over one megawatt of power in a single UPS while boasting up to 97% efficiency, it is the first true on-line double conversion UPS at this power level to deliver the highest efficiency across all load levels. In addition, it is smaller in size and lighter in weight than competing products. As one of the largest manufacturers of IGBT’s in the world, Mitsubishi Electric is able to achieve superior UPS performance and reliability through smarter control of the IGBTs. The 9900C incorporates a Digital Signal Processor (DSP) and Direct Digital Control (DDC) to realize the full benefits of the latest generation of IGBTs, a reduced total cost of ownership, and improved PUE over conventional UPSs

9900D Video

The 9900D Series Uninterruptible Power Supplies from Mitsubishi Electric offer the highest reliability to satisfy the relentless demands of cloud and colocation data centers. The 9900D is responsive, shielding from power transients with advanced control and power module redundancy. An ideal UPS for data centers, it provides high-speed sampling and switching and is capable of operating in higher temperatures at higher altitudes. While it is a large UPS, it’s significantly smaller than competitive models within its output range, and its efficiency allows you to do more with a single unit than competitors. This combined reduces gray space, cabling and installation time, and freight costs.
