Redundant Power Sources
i.e. Two UPs Inputs, One Output
transfer switch enables redundant UPS, backup generators, DC to AC inverters, or other AC power
sources to be used for a single load. TSi 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 sinewave 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 Features/Series
Table, or at the more detailed descriptions further
down, to determine
the ATs series you need. In the table, click on the

~Two 120V inputs, one 120V output.
~Two 208/230/240V inputs, 1 output.
TSi Power’s ATs Series user customizable AC Automatic Transfer Switches
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 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 plug/receptacles. An eight
receptacle output unit is also available.
Custom OEM solutions are also possible.
- For UPS Maintenance Bypass
~ Two 120V AC inputs, one 120V output, 15 Amps.
~ Two 208/230/240V AC inputs, one output,
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 & 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.
- For UPS Maintenance Bypass
ARm-1000FAA ~ Two 120V AC inputs, one 120V output, 15A.
Same as above ARm Series, but this redundant transfer switch has a wider and deeper enclosure to facilitate
more universal rack-mounting systems.
Kits For ARm & 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, INv,
TSi Power is also a custom
automatic transfer switch & bypass manufacturer.
