ATS system on a 200A switch

ATS systems on the switch – automatic power supply safety

Auxiliary power supply (AWS) cabinets based on a switch are a proven method for automatic power switching between the mains and a generator. The basic version relies on a control signal from the generator, making it ergonomic and easy to use. The advanced version, equipped with its own controller, allows for the operation of multiple AWS cabinets with a single generator and the expansion of the system with additional functionalities. Upon request, the AWS can be manufactured in a four-pole version and adapted for outdoor operation.
