ATS system on 200A contactors

ATS systems on the contactor – reliability of power supply automation

Contactor-based standby power supply (ATS) cabinets are a simple, proven, and reliable solution for applications requiring automatic power transfer from the mains to a generator. The basic version operates based on a signal from the generator, ensuring simple and ergonomic operation. The extended version, with its own ComAp controller, allows for the operation of multiple ATS cabinets with a single generator and the construction of more complex automation systems. Upon request, the ATS can be manufactured in a four-pole version and adapted for outdoor installation.
