ATS system on 150A contactors

ATS systems on the contactor – automatic power supply safety

Contactor-based standby power supply (ATS) cabinets are a proven solution for automatic power transfer between the mains and a generator. The basic version operates based on a control signal from the generator, ensuring simple and ergonomic operation. The extended version, equipped with a dedicated ComAp controller, allows for the control of multiple ATS cabinets with a single generator and expansion of the entire automation system. Upon request, the ATS can be manufactured in a four-pole version and adapted for outdoor installation.
