SKR2-A ATS controller is designed to work with automatic transfer switch. It's based on the micro-processor techonology. Controller can accurately detect the three/single phase(s) voltage of the dual power supplies, make accurate judgement of voltage anomalies (power loss, over voltage, under voltage, phase missing, over frequency, under frequency), and control the switching delay.
It's suitable for the ATS with one breaking position or no breaking position.
Controllers have the function of sending generator start signal after delay when power 1# becomes abnormal.
Using RS485 communication interface, controllers realize functions of remote measurement, remote communication and remote control.
