M90 Modular Online Three Phase UPS


208/120VAC Three Phase

Mission Critical Availability while reducing costs with Scalable M90 Online UPS for 15kVA, 20kVA, 30kVA, 40kVA, 45kVA, 60kVA applications.

The M90 is a scalable modular online three phase UPS that protects critical data and equipment from power problems, while supplying clean and reliable network grade power.

The M90 can be configured with a fully redundant power module and battery modules. Should one module fail, the remaining modules smoothly take over the load. Because the power modules are independent, they can be hot swapped without risk to the critical load.
As power requirements change, M90 modularity makes it easy to add modules and increase capacity.
