HAT530双电源控制器， 适用于溯高美开关。HAT520双电源控制器，可精确检测两路三相电压、两路单相电压，对出现的电压异常(失电、过压、欠压、过频、欠频、缺相、逆相序)做出准确的判断，经延时后控制ATS切换。适用于控制无分断位ATS开关，控制器具有一路电源异常延时后发出起动发电机组信号的功能。

HAT520ATS 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 transferafter the delay has expired. This controller is suitable for NO Breaking ATS.When 1# is abnormal, the controller will send signal to start genset after the"1# abnormal delay" has expired.
图形液晶显示模块，各种交流制式采样，适合控制所有ATS。溯高美电源开关，让生活更美好。
