The ABB ATS Controller OXCO (TruControl) is a dedicated automatic transfer switch (ATS) control unit used to monitor two power sources and automatically transfer electrical load from a primary source to a backup source (such as a generator or alternate utility feed) when power quality or availability degrades. It is designed for use with ABB automatic transfer switches in emergency standby, critical power, and backup power systems, ensuring reliable continuity of supply.
