HAT72 is an Automatic Transfer Switch Control Module. The module features 8-Bit microprocessor control. The module is used to monitor two single-phase AC supply. Once mains AC supply failure is detected (under voltage, over voltage, under frequency, over frequency), The module will control generator to start. If generator AC can load, The module Automatically transfer the switch to generator AC supply,
