Now You Can Have Dual Cord Dependability
For All Your Critical Systems
If your electronics application is one of the many that
requires continuous operation — without tolerance for even
scheduled downtime — you need the reliability provided by
dual power sources.
Many of today’s servers and other computing systems
are equipped with dual power cords…designed to
provide built-in redundancy by allowing connection to
two separate power sources. In a similar move, facilities
are now introducing this level of dual cord reliability to
critical equipment that operates on a single power input
by supplying two independent electrical feeds. The key
to making it all work, however, is to have a dependable
switching mechanism to support it.
What Makes A Reliable Switch?
The transfer switch should have proven technology and
design features to ensure that it will operate dependably
when you need it. The swihching mechanism should be
easy to configure, install, use and maintain.
A switch needs to operate swiftly and reliably enough to
compensate for “fast” power failures such as UPS system
failure, circuit breaker trip or operator error — without
affecting operation of the protected equipment.
The Liebert SmartSwitch does exactly this by providing
rapid switching between two independent AC power
sources, for uninterrupted operation of critical
electronic equipment.
Liebert SmartSwitch Enhances The
Availability Of Power To Your Critical
Electronic Equipment
Modeled on proven UPS technology, the Liebert
SmartSwitch point-of-use power transfer switch is
placed at the most effective spot — the last
connection upstream of the protected equipment —
allowing dual AC power paths all the way up to the
critical load. From design to operation and maintenance,
Liebert SmartSwitch has the features that optimize

or UPS sources, allowing dual AC power
paths all the way up to the critical load.
Features & Benefits
Flexibility:
■ Transfers manually or automatically.
■ Allows selection of preferred input source
without rewiring or load shutdown.
■ Provides integral maintenance bypass to both
input sources for servicing convenience.
Higher Availability:
■ Switches quickly between two AC power sources,
making power transfer time invisible to your
protected equipment.
■ Allows module replacement without load
shutdown, with hot-swap electronics.
■ Employs Break-Before-Make switching to
eliminate connecting together of the
independent power sources, even under faulted
conditions.
Lowest Total Cost Of Ownership
■ Detects potential switch failures before the
problem becomes critical, through diagnostics
and transfer tests.
