A three phase to single phase automatic transfer switch for providing power to at least one single phase power load from one of a primary and a secondary source of three phase power. The automatic transfer switch includes three pairs of switches, wherein each pair of switches is connectable to the primary and the secondary sources of three phase power, wherein each switch operates in unison with the other switch within its pair, wherein each pair of switches is connectable to a different one of the at least one single phase power load, and wherein each pair of switches is operable independently of the other pairs of switches. The three phase to single phase automatic transfer switch also includes one or more controller in communication with each of the pairs of switches, the controller configured so that, when power from the primary source of three phase power is lost or degraded, the controller connects each pair of switches independently of each of the other pairs of switches from the primary to the secondary source of three phase power.

Automatic transfer switch for three-phase applications

An uninterruptible power supply having an input connector for receiving AC power from a centralized source of electric power such as a power grid of an electric utility company, a first electric outlet, and a second electric outlet for delivering AC power, a first switch for selectively allowing AC power therethrough to the first outlet, a second switch for selectively allowing AC power therethrough to the second outlet: and a controller operable to control the second switch so that AC power is delivered to the second outlet a predetermined amount of time after AC power is delivered to the first outlet (i.e., after a time delay).
