Uninterruptible Power Supply Systems
UPS systems with unrivaled reliability and superior efficiency to ensure your business doesn’t go dark.
Uninterruptible Power Supplies
Industry-leading reliability from 6-2000kVA
Uninterruptible power supply failures remain the leading cause of power outages across the data center industry1. With the relentless demands on today’s mission critical facilities, selecting highly reliable – tested and proven – UPS equipment is critical.
Whether you operate a hyperscale data center that demands a power dense UPS or a network that needs a compact single-phase backup, Mitsubishi Electric’s UPS systems are designed to be resilient and robust, keeping your business from going dark.
“It’s extremely robust and, quite frankly, I have a lot less people coming to my site operating and maintaining them as opposed to other vendors’ equipment.”
3 Phase UPS Systems: 10kVA – 2MW
Single Phase UPS: 6-12kVA
Our single-phase system is the 7011B, commonly used to back up individual computers, standalone IT racks, or other applications with limited load (less than 10kVA).
Mitsubishi Electric UPS Technology
Beginning with the use of IGBTs for converters and inverters and followed by 3-level topology and transformerless UPS designs, Mitsubishi Electric has long been at the forefront of offering uninterruptible power supplies with the highest efficiencies and unparalleled reliability.
Unparalleled Reliability
At 99.9995%, Mitsubishi Electric Uninterruptible Power Supplies achieve the highest equipment reliability among UPS suppliers, ensuring you – and your customers – are protected against downtime 24/7/365. We calculate our equipment reliability as the percentage of time our backup power systems have sustained their load carrying capacity.
e = # of reported customer load loss events due to a Mitsubishi Electric UPS failure
d = Assumed maximum duration of load loss events
u = # of Mitsubishi Electric uninterruptible power supplies shipped
tn = Assumed total available operational hours of UPS n since shipment
By manufacturing and heavily testing the advanced power electronics used in our UPS systems, we possess intimate knowledge on how to control them. High speed sampling and switching deliver hyperscale performance and value –
- Achieving the highest levels of efficiency under all load conditions
- Increasing cost savings & longer product life from cooler operation
- Possessing the flexibility to operate in higher temperatures
Efficiency Across the Load Range
Our superior expertise in optimizing power device control is evident by the consistently high efficiency curves across our UPS product line.
Considering loads in data centers can range anywhere from 25% to 80%, demonstrating high efficiency across all load levels is a critical element of UPS reliability and performance.
Online Double Conversion
Achieve clean, consistent power with online double conversion technology. By filtering and converting incoming AC power to DC and back to clean, stable AC, online double conversion UPS systems deliver reliable power conditioning to protect critical loads from transient or voltage anomalies.
Explore the differences between double conversion vs. line interactive.
UPS System Configuration & Redundancy
The complexity of each UPS configuration varies based on budget, uptime requirements, risk aversion, maintenance plans, and existing infrastructure.
Mitsubishi Electric’s Project Application Engineering team will configure a customized critical backup power system, incorporating batteries, maintenance bypasses, paralleling gear, and more to support your application.
UPS Testing & Quality
As a prerequisite for success, every UPS system from Mitsubishi Electric and furnished with a signed factory test report prior to shipment. Our clients are encouraged to view real-time data and results via a product demonstration or a factory witness test of their purchased system – a great opportunity to simulate on-site needs.
“It was really cool to be able to prop open the doors and see the inside and be given an explanation of what all the parts and pieces were and how they worked”

FAQs About UPS Systems
Redundancy in a UPS can refer to either internal module redundancy or system level redundancy.
- Internal redundancy is when there are additional power modules in a UPS that are available to carry the load in the case of a fault condition in another module.
- System level redundancy is when there are multiple UPS in a system that are available to carry the load in the case of a fault in an entire UPS.
Learn more about the types of redundant systems.
The efficiency of a UPS is the ratio of the output power to the input power and shows the internal losses of the system.
Calculation: Efficiency = (Output Power / Input Power) x 10
For example, if the output power of the UPS is 100kW and the input power is 103kW the resulting efficiency is 97%.
Mitsubishi Electric has multiple energy-efficient UPS products to support your critical load. Currently, our most energy-efficienct UPS is the SUMMIT Series® (500 & 750kVA). The 9900AEGIS (80-225kVA) is also ENERGY-STAR rated.
Choosing the right size UPS is dependent on a variety of factors, from application to capacity needs, amongst others.
Here, we walk you through the basics of determining what size UPS is best to support your critical infrastructure: What Size UPS Do I Need? The Basics of Sizing a UPS
- An internal bypass is located inside the UPS itself and provides an alternate path for power to flow, “bypassing” the power electronics. The internal bypass, however, does not isolate the entire UPS, and power is still present at the input and output connections.
- A maintenance bypass is an external piece of equipment, typically containing circuit breakers, that provides an alternate path for power to flow around the entire UPS. This allows you to remove power at the input and output connections allowing technicians to safely perform work on the equipment.
In general, a UPS battery is an energy storage device that goes into effect when the critical utility power of a UPS system is offline. Then, the UPS switches to drawing power from the battery to keep critical loads online and running.
The UPS battery can be of a variety of DC technologies and/or energy storage devices, and it is a critical component of a UPS system.
Choosing a battery depends upon the UPS system’s specific use case. This use case depends on the technical, safety, and commercial requirements of the customer.
It is recommended to never run a UPS at 100% load capacity. Most are run at a 60-75% capacity. This can vary based on the design of the facility, type of load, and/or the redundancy of the system.
Learn more about the basics of UPS sizing.
Typically, a Mitsubishi Electric UPS has a design life of approximately 15 years.
