Single phase UPS systems are designed to support technology with lower backup power requirements. This makes a single
phase power supply ideal for individual computers and IT closet applications.

208V / 6-12 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 on-premise edge data centers and network towers, individual computers, 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.

Mitsubishi Electric Single Phase UPS Features

True online double conversion.

A lot of single phase UPS systems in this capacity range are line interactive designs, meaning the load is directly connected to the incoming AC power supply. This subjects the load to any power fluctuations present in the raw power source, potentially disrupting operations downline that may be sensitive to power supply anomalies.

Mitsubishi Electric’s 7011B is a true online double conversion UPS, meaning that the inverter is always on, supplying a consistent and clean supply of power.


Although the smallest UPS in Mitsubishi Electric’s line-up, the 7011B single phase design does not skimp on technological advances. Like all the other Mitsubishi Electric models, it is a transformerless, IGBT-based, true online double conversion UPS. Its design features distinct UPS modules that support expansion and make repairs simpler.
