Reliability and Flexibility
Parallel control circuitry, system static bypass and control circuitry reside in each individual Multi-Module System UPS, optimizing control redundancy and eliminating common control single points of failure. This results in highly reliable system architecture.

For many installations, System Expansion with the addition of UPS modules is required if future load demand becomes apparent. For most MMS available today, the reverse scenario of System Reduction with the capability of utilizing the removed UPS module is not possible without UPS module modification. With the Mitsubishi Electric MMS, not only System Expansion but also System Reduction is possible, with the capability to utilize the removed UPS module for Single Module System (SMS) applications, because each UPS module has independent static bypass and control circuitry. This System Expansion and Reduction results in a highly flexible system configuration.
