1. GENERAL
1.1 PRODUCT APPLICATION
The ATS series of automatic transfer switches is designed for applications where two or more
autonomous power sources are available. The ATS can be utilized as single or multiple units for
different levels of redundancy. Applications include but are not limited to telecom, computers,
data centers, industrial control, automatic test equipment, oil exploration and utilities.
The ATS works with asynchronous or out-of-phase power sources which allows them to be used
with a number of different sources. Customers with special requirements can be offered custom
programming to address special use situations. 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 in typically ½ cycle (or ~8 ms) for 60 Hz and
typically ½ cycle (or ~9.7 ms) for 50 Hz. Upon return of primary power, the ATS will switch back
in typically ½ cycle (or ~8 ms) for 60 Hz and typically ½ cycle (or ~9.7 ms) for 50 Hz. This is fast
enough to be invisible to even the most sensitive equipment.
