Typical UPS configurations
Configuration
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
The dual-bus system is suitable for scenarios where high availability
requirements are posed for power supply. The dual-bus system
supplies power to important loads in large- and medium-sized
equipment rooms and data centers.
In addition to common parallel system advantages, the dual-bus
system also provides outstanding availability and eliminates
bottleneck failures. However, configuration of the dual-bus system is
complex.
A 1+1 parallel system is a typical configuration. You can set the number of requisite UPSs and
redundant ones on the LCD or WebUI.
2.4.1 Single UPS
The UPS uses a modular design in which multiple power modules are connected in parallel to
deliver a high loading capacity. If a single power module is faulty, the other power modules
continue working. When the load power is small, even a single UPS can provide redundant
capacity, which ensures high reliability.

UPS.
