The KS ATS 4/25 Inverter automatic transfer switch from the German brand Könner & Söhnen automatically starts the generator and transfers the load to it when mains power fails, then stops the generator when the central power supply is restored. It is compatible with the KS 5500iES ATSR inverter generator equipped with an integrated 7-pin ATS connector.
The programmable controller allows setting the engine start delay after a power outage and the warm-up time before connecting consumers, and signals errors. The unit operates in automatic or manual mode, keeps the battery charged and includes a generator emergency-stop button.
