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

e equipped with dual power cords…designed to

ar
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

ffecting operation of the protected equipment.
