Power’s ATs Series user customizable automatic
transfer switches
(ATS) are for enabling the use of redundant
power sources, such as small Uninterruptible Power Systems feeding
industrial controls, PLC cabinets, internet servers; dc-ac inverters
feeding telecom systems, etc.
Typical ATs
Series applications
Designed
for situations where reliability and predictability matter to the
enterprise.
Examples: telecommunications equipment, rectifiers, cell sites, file
servers, routers, digital copiers, office machines, industrial
controllers (PLC), automatic test equipment (ATE), laboratory analyzers
and other sensitive, specialized microprocessor-based equipment.
Key automatic
transfer switch benefits
If
the ATs DIP Switch is set to "fast transfer" (20ms typical
transfer time) mode, then, when redundant power sources are present, it
can replace an expensive UPS system and battery banks for most
computers, telecommunication, and industrial equipment (since
switchmode power supplies used in most new electronics equipment provide
a minimum of 20ms in capacitor hold-up time under full load conditions).
If a ‘positive power break’ is needed during the transfer, then the
ATs may be set to "slow transfer" (1 second) mode to ensure a
full 1 second ac power outage during transfer.
Also, the two ac
sources do not have to be synchronized since the ATs is
designed to switch between two asynchronous ac sources without damage to
itself or to equipment powered by switchmode power supplies. Note, both
power sources must be sine wave, i.e. UPS even while on battery backup
(some UPS are only modified square waves when on battery backup)
How ATs automatic
transfer switches work
The ATs
is fed by two ac power sources. When the primary power source detector
circuit senses a loss of power on that circuit, it immediately switches
the load over to the backup power source feed in less than 20ms. This
is fast enough to be invisible to computer switch-mode power supplies.
Circuit breakers protect the system against over-voltages and surges. |
