Single UPS
The UPS uses a modular design. It uses multiple power modules connected in
parallel to deliver a high loading capacity. If one power module is faulty, other
power modules continue working. If loads are light, the UPS provides redundant
capacity even if only a single UPS is operating, which ensures high reliability.

Parallel System
In a parallel system, mains input, bypass input, and AC output terminals of UPSs
are connected in parallel. Energy control modules (ECMs) on different UPSs are
connected over parallel cables to synchronize UPS outputs to supply power to

Application Scenario
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
multi-bus system is free from
bottleneck failures, but its
configuration is complex.
NO TE
For the three-phase four-wire model, if the mains and bypass inputs use different power
sources, ensure that the neutral wires of the mains and bypass input power sources are
equipotential. For example, the mains and bypass inputs are from the same transformer.
