2.1 System Description
The Liebert APS power system is a modular UPS that provides high reliability. It is intended for use with
workstations, servers, networks, telecoms and other sensitive electronic equipment. It provides
continuous, high-quality AC power to your equipment, protecting it from any power disturbance due to
blackouts, brownouts, surges or noise interference.
The Liebert APS UPS is an easily adaptable UPS system. By installing additional power or battery modules,
you can expand your current system capacity, extend your back-up runtime, or provide redundancy. The
user interface lets you configure the operation according to application requirements. It also informs you
of the status of the UPS and keeps a log of events.
The Liebert APS series UPS contains both transformer-free and transformer-based UPS frames. The use
of the transformer-free or transformer-based frames depends on the specific application requirements.
The appearance of the different frames is shown in Figure 2.1 on the next page through Figure 2.4 on
page 15.
