2.6.1 Single UPS
This series 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.

2.6.2 1+1 Parallel System

In a 1+1 parallel system, mains input, bypass input, and AC output terminals of UPSs are
connected in parallel. ECMs on different UPSs are connected over parallel cables to
synchronize UPS outputs to supply power to loads. If one UPS fails, another UPS continues
supplying power to loads, which ensures system reliability.

Application Scenario
Supplies power to common loads.
Supplies power to large-sized data centers or important loads. It
features high reliability and strong transient overload resistance
capability.
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 configuration is
complex.
