The KS ATS 4/25 Gasoline ATS (Automatic Transfer Switch) unit from the German brand “Könner & Söhnen” automatically starts the generator and transfers the load to it when the main power source is cut off, and automatically stops the generator when the main power supply is restored. It is compatible with inverter-type gasoline generators that feature an 8-pin connector for automatic transfer units (ATS input).

The ATS unit includes a PLC for programming the generator start time after a power outage, the pre-heating duration before connecting to consumers, and for fault warning alerts. It also contains an emergency stop button for the generator. The ATS unit can operate both automatically and manually.
