Contactor-based ATS systems – reliable power switching on a small scale

Auxiliary power supply (AWS) cabinets with a contactor are a simple and reliable solution for automatic power transfer between the mains and a generator. The basic version operates based on a signal from the generator, allowing for easy and cost-effective operation. The extended version, with its own ComAp controller, allows for the operation of multiple AWS cabinets with a single generator and the construction of more advanced automation systems. Upon request, the AWS can be manufactured in a four-pole version and adapted for outdoor installation.
