M90LU Unity PF Modular Online Three Phase UPS


208/120VAC Three-Phase

Mission Critical Availability while reducing costs with Scalable, Modular M90L for 15kVA, 20kVA, 30kVA, 40kVA, 45kVA, 60kVA applications.


The M90LU 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.

M90LU can be configured with a fully redundant power module and long runtime external batteries. 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, M90LU modularity makes it easy to add modules and increase capacity.
