Combines Power Distribution And
Automatic Switching
With a single, space-saving unit, the Liebert
Static Transfer Switch2/Power Distribution Unit
combines the switching capabilities of the
STS2 with the benefits of a proven power
distribution unit.
Liebert designed the STS2/PDU to bring you a
distribution system that will close the power
delivery loop in your critical facility. It offers the
benefits of a custom-tailored power system,
with the convenience and cost savings of a pre-
packaged, factory-tested unit.
Housed in a single, self-contained cabinet, it
combines distribution, computer-grade
grounding, isolation, and power monitoring, as
well as dual-source switching, to provide the
protection your vital computer or
communications equipment demands.
Available in capacities from 250 to 800 amps,
the Liebert STS2/PDU offers flexible expansion
capabilities to fit growing sites. The packaged
system approach of the Liebert STS2/PDU is
convenient and space-saving, reducing
installation time and cost compared to a
conventional approach using multiple
interconnected components.

Liebert Datawave
Regardless of the quality of input
power, Liebert Datawave magnetic
synthesizer power conditioning
system generates a stable output
waveform to distribute to your
s
ensitive electronic equipment. The
self-contained system can be used
to condition utility power, distribute
it to sensitive electronics, and
monitor power parameters.
Li
ebert Datawave magnetic
synthesizer is available in 15-200
kVA capacity systems for raised
floor applications and 50-200 kVA
capacities in top-exit models for
non-raised floors. The system
synthesizes, conditions and
distributes three-phase output
voltage, regardless of input
quality, providing transient
voltage protection and harmonics
isolation, even with non-linear
loads and distorted input voltages.
