ATS system on 110A contactors

ATS systems on the contactor – automatic power supply safety

Contactor-based standby power supply (ATS) cabinets are a reliable and simple solution that automatically switches power between the mains and the generator. The basic version relies on a control signal from the generator, ensuring reliable yet ergonomic operation. The extended version, with its own ComAp controller, allows for the operation of multiple ATS cabinets with a single generator and the creation of more complex automation systems. Upon request, the ATS can be manufactured in a four-pole version and adapted for outdoor installation.
