TSi Power
Automatic Transfer Switch

For Enabling Using 
Redundant Power Sources 
i.e. Two UPs Inputs, One Output


A
n automatic 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 hyperlink bookmark, such as 'ARm,' to go to that ATs series summary. If you then want more detailed specifications, click on the underlined PDF hyperlink.

The ATs Series
ATs-1000-30A-40A ~Two 120V inputs, one 120V output.
ATs-1000-30A-40A
~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.

    

The ARm Series - For UPS Maintenance Bypass
ARm-1000 ~ Two 120V AC inputs, one 120V output, 15 Amps. 
ARm-1000
~ Two 208/230/240V AC inputs, one output, 10 Amps.
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.
The ARm-FAA Series - 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.

Rack-Mounting Kits For ARm & ATs Series
Rack-Mount 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, or UPs.

TSi Power is also a custom automatic transfer switch & bypass manufacturer.
