Title
(EN) REVERSE FLOW AUTOMATIC TRANSFER SWITCH
(FR) COMMUTATEUR DE TRANSFERT AUTOMATIQUE À FLUX INVERSE
Abstract
(EN)
Systems and apparatuses include an automatic transfer switch including a source pole coupled with a power source, a first load pole coupled with a first load, a second load pole coupled with a second load, a first switch selectively coupling the first load pole to the source pole, and a second switch selectively coupling the second load pole to the source pole.
(FR)
