Abstract
An automatic transfer switch (100) for automatically switching an electrical load between two power sources is provided. Two power cords (106) enter the ATS (A power and B power inputs) and one cord (109) exits the ATS (power out to the load). The ATS has indicators (107) located beneath a clear crenelated plastic lens (108) that also acts as the air inlets. The ATS (100) also has a communication portal (103) and a small push-button (104) used for inputting some local control commands directly to the ATS (100). The ATS (100) can be mounted on a DIN rail at a rack and avoids occupying rack shelves.
Claims18
An automatic transfer switch system, comprising:
- a switch unit having a first input for receiving a first power signal via a first power cord extending between said switch unit and first power outlet associated with a first power source, a second input for receiving a second power signal via a second power cord extending between said switch unit and a second power outlet associated with a second power source, an output for providing a power signal to a connected load, and a switch for selectively connecting one of said first and second inputs to said output depending on a power signal status of at least one of said first and second power signals, wherein said switch unit comprises a switch relay for selectively connecting one of said first and second inputs to said output and a power surge managing circuit includes a gatekeeper relay disposed in series with said switch relay;
- a sensor device for sampling a selected signal comprising at least one of said first and second power signals to provide power signal information concerning said power signal status;
- and
- a communications device, associated with said sensor device, for communicating said power signal information to a remote platform.
A method for operating an automatic transfer switch system, comprising:
- providing a switch unit having a first input for receiving a first power signal via a first power cord extending between said switch unit and first power outlet associated with a first power source, a second input for receiving a second power signal via a second power cord extending between said switch unit and a second power outlet associated with a second power source, an output for providing a power signal to a connected load, and a switch for selectively connecting one of said first and second inputs to said output depending on a power signal status of at least one of said first and second power signals, wherein said switch unit comprises a switch relay for selectively connecting one of said first and second inputs to said output and a power surge managing circuit includes a gatekeeper relay disposed in series with said switch relay;
- operating a sensor device for sampling a selected signal comprising at least one of said first and second power signals to provide power signal information concerning said power signal status;
- and
- operating a communications device, associated with said sensor device, for communicating said power signal information to a remote platform.
