Description
Multi-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
multi-bus system is free from
bottleneck failures, but its
configuration is complex.
Dual-bus supported
NO TE
If the mains and bypass 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.
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. 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.
