Conguration
Application Scenario
Single UPS Supplies power to common loads.
Parallel system Supplies power to important loads in small- and medium-
sized data centers. It features high availability and strong
transient overload capability.
Dual-bus system Supplies power to important loads in large- and medium-
sized equipment rooms, data centers, and other places that
require high reliability.
In addition to advantages of common parallel systems, the
dual-bus system is free from bottleneck failures, but its
conguration is complex.
A 1+1 parallel system is a typical conguration. You can set the number of requisite UPSs
and redundant ones on the LCD or WebUI.
