M90U Unity PF 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 M90U is a scalable modular online double conversion UPS that protects critical data and equipment from power problems while supplying clean and reliable network grade power.

M90U can be configured with a fully redundant power module and battery modules. Should one module fail, the remaining modules smoothly take over the load. The power modules are independent and can be hot swapped without risk to the critical load.
