Original HAT520N Dual Power ATS Controller HAT520N replace HAT220A/240A Automatic Transfer Switch Control Board

HAT520N Dual Power ATS Controller is made by the core of the microprocessor, which can precisely detect 2-way 3-phase voltages, 2-way single phase voltages and make accurate judgment for the occurred abnormal voltages (lost of power, over voltage, under voltage, over frequency, under frequency, loss of phase, phase sequence wrong), controlling ATS switchover after delay. It is suitable for controlling No Breaking ATS, and it has the function of issuing genset start signal after abnormal delay of one way. By LINK communication port, "three remotes" (remote measurement, remote communication and remote control) function can be realized.
