| The
TSi
Power 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 to 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 switch mode 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.
How the automatic
transfer switches (ATs) 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 20 ms. This is fast enough to be invisible to
computer switch-mode power supplies. Circuit breakers protect the system
against over-voltages and surges. |
