ATS system on an 800A switch

ATS systems on the switch – automatic reliability

Auxiliary power supply (AWS) cabinets with a switch are a practical and proven solution wherever automatic switching between the mains and a generator is crucial. The basic version relies on a control signal from the generator, making it simple and ergonomic. An extended version with its own controller allows for the operation of multiple AWS cabinets with a single generator or the construction of more advanced automation systems. Upon request, the AWS can be manufactured in a four-pole version and adapted for outdoor operation.
