SFPTautomaticTransferSwitch

Automatic Transfer Switch..  An ATS is a piece of electrical equipment that is used to monitor and automatically connect the best of two power sources to an electrical load. Normally at least one of the two power sources is a generator set that is directed by the ATS to start when the primary power source has failed.
