using redundant power sources such as a UPS and an inverter,
i.e. two ac inputs, one ac output
transfer switch enables redundant UPS, backup generators, dc to ac inverters, or other
sources to be used for a single load. Automatic transfer switches (ATS)
are recommended when no downtime from a power outage is tolerated. Typical
applications for transfer switches include internet service providers, critical servers and telecom
equipment, and export markets with bad power. These rack-mountable ATS (
using below rack-mount
kits ) permit daisy
chaining with any sine wave UPS, providing unlimited redundancy using any
combination of independent (separate) ac circuits, UPS systems,
generator-backed ac circuits, and so on. In a sense you can compare ATS
strategy with RAID strategy (redundant arrays of inexpensive disks).
Please look at the
table, or at the more detailed descriptions further
down, to determine
the ATs series you need. In the table, click on the

- for redundant ac power
The TSi Power ATs Series user customizable ac automatic transfer switches
in 30 amperes and 40 amperes at 120 vac or 230 vac configurations are for enabling the use of redundant power sources, such as small
uninterruptible power systems feeding industrial controls, PLC cabinets,
internet servers, telecom systems, etc.
The ATs Series rack-mountable automatic
transfer switch utilizes
solid-state transfer relays with user selectable transfer times, and allows
asynchronous backup power sources (sources do not have to be in phase with
each other). ATs units incorporate DB9 communications ports and
built-in circuit breakers. They come in a standard hardwire configuration,
and can be ordered with optional cords and plugs/receptacles. An eight
receptacle output unit is also available. Custom (bespoke) OEM solutions are also possible.
You may want to consider two ATs units for
some extremely mission-critical applications, such as the power for the
telecommunications switch for traffic from Antarctica to North America,
which is powered through a doubly redundant system, utilizing two
~ two 120V ac inputs, one 120V ac output.
~ two 208/230/240V ac inputs, one ac output.
- for UPS maintenance bypass
TSI Power's automatic
redundancy module is designed to provide absolute power protection for
your mission-critical computers and equipment. It will provide
uninterrupted ac to your load even in the event of one UPS failure.
ARms your critical equipment against
extended power outages and catastrophic system shutdowns caused by
accidental circuit breaker trips, UPS overload conditions, weak or old UPS
batteries, routine and preventive maintenance of UPS, accidental UPS
shut down, loose power cords, or UPS failure.
Note: Since these require two synchronized power inputs, these are most
often used as UPS maintenance bypass units.
~ two 120V ac inputs, one 120V output, 15 amps.
ARm-1000E ~ two 208/230/240V ac inputs, one output, 10
kits for ARm and ATs Series
kits enable TSi's ARm and ATs automatic transfer switch products to be placed virtually
anywhere that fits your space considerations. This includes desktop
and floor mount options. If a rack mount configuration
is what you require, TSi's ARm-FAA and ATs systems are designed to accommodate
most standard component rack enclosures. With a simple rack mount kit
option, you can place your ARm, ATs, rack-mountable UPs, and/or INv, in either a 19". 23", and 24" rack and
facilitate the space requirements of your systems, not the ARm, ATs, XINv,

So for browsing the products and spec sheets, the book is actually quite a
fast look-up resource once you have it on your desktop.
