ATS system on a 1000A switch

ATS systems on the switch – reliable power supply automation

ATS cabinets based on a switch are an indispensable solution wherever automatic switching of power sources is required – from the mains to the generator and vice versa. The basic version operates entirely thanks to a signal from the generator controller, making it simple and ergonomic. The extended version, with its own controller, allows for the operation of multiple ATS cabinets by a single generator, as well as the construction of more complex automation systems. Upon customer request, the ATS can be manufactured in a four-pole version and adapted for outdoor installation.
