SmartGen HAT520N ATS controller The powerful Microprocessor contained within the HAT520N ATS controller allows for precision voltage (2-way 3-phase/single phase) measuring and make accurate judgment on abnormal voltage (power lost, over/under voltage, over/under frequency, loss of phase, phase sequence wrong) and control ATS to transfer after the delay has expired. This controller is suitable for NO Breaking ATS. When 1# power is abnormal, the controller will send a signal to start Genset after the “1# abnormal delay” has expired. “Three remote” (remote control, remote measurement, and remote communication) function can be implemented with the help of the LINK communication port.
