The ATS (Automatic transfer switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected.
Gasolineand diesel generators with an electric starter are equipped with a universal 5-pin connector for an automatic transfer switch unit (ATS input). The ATS unit has a PLC that allows the automatic start/stop of the generator to be programmed in the event of a power outage and after its restoration.PROGRAMMABLE LOGIC CONTROLLER OF THE ATS UNIT:
– Automatic/manual operation
– Programming of engine starting time after power outage
– Programming of engine warm-up time before connecting to consumer
– Setting of starter operation time
– Engine performance monitoring
– Battery charging when the generator is off

The generator is suitable for connecting the ATS (Automatic Transfer Switch) system.
The ATS (Automatic Transfer Switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected and automatically stops the generator when the central power supply is restored. ATS output has a 6-pin connection.


“Könner & Söhnen” generators are equipped with an enlarged steel fuel tank, which extends the generator’s operating time without refueling. The fuel level indicator is located on the tank for ease of use.

Reinforced steel frame

Könner & Söhnen twin-cylinder models feature a reinforced steel frame and dual anti-vibration system. In addition, the generators have a transportation kit for easy movement.

Increased warranty

Increased warranty

Heavy Duty series diesel generators have the extended warranty – 2 years or 3000 operating hours (whichever comes first) under condition of proper operation and scheduled maintenance.
