Automatic transfer switch system capable of governing the supply of power from more than two power sources to a load
First Claim
1. A system for governing the providing of power from first, second and third power sources to a load, the system comprising:
- a first Automatic Transfer Switch (ATS) device having first and second input ports and a first output port;
a second ATS device having third and fourth input ports and a second output port; and
at least one communication link coupling the first and second ATS devices,wherein the second output port of the second ATS device is coupled to the second input port of the first ATS device, andwherein a first signal is provided from the first ATS device to the second ATS device by way of the communication link when power should be supplied from the second ATS device to the first ATS device.

Abstract
An automatic transfer switch (ATS) system and method of operating an ATS system for governing the providing of power from first, second and third power sources to a load are disclosed. In one embodiment, the system includes a first ATS device having first and second input ports and a first output port, a second ATS device having third and fourth input ports and a second output port, and at least one communication link coupling the first and second ATS devices. The second output port of the second ATS device is coupled to the second input port of the first ATS device. Additionally, a first signal is provided from the first ATS device to the second ATS device by way of the communication link when power should be supplied from the second ATS device to the first ATS device.

13. A method of controlling the delivery of power from first, second and third power sources to a load, the method comprising:
-
providing a first Automatic Transfer Switch (ATS) device having first and second input ports and a first output port, and a second ATS device having third and fourth input ports and a second output port, wherein the second output port is coupled to the second input port and wherein the second ATS device is additionally coupled to the first ATS device by a communication link; providing a control signal from the first ATS device to the second ATS device by way of the communication link when it is determined that a first condition has occurred; providing, by way of the second ATS device, power being supplied to at least one of the third and fourth input ports to the second input port of the first ATS device. - View Dependent Claims (14, 15, 16, 17, 18, 19)
