HAT310-120V ATS Controller is suitable for 2-stage of PC, and ATS of CC class (close signal isconstant output). It can accurately detect 3-phase 4-wire mains voltage and generator single phase voltage. When mains under voltage and loss of phase occurred, HAT310-120V will control ATS transferafter delay. If mains are unavailable, the controller has the function to initiate signals to start gen-set.

HAT310 controller can detect 3-phase 4-wire mains voltage/generator single phase voltage and control ATS.
