High-performance and robust L-twin air-cooled two-cylinder four stroke engine (21 hp). The engine design is more balanced thanks two cylinders in line, which ensures reduced vibration of the generator during operation.


All-weather anti-vandal housing provides effective protection for the device and extends its service life. The housing has an external emergency stop button. In addition, the housing is equipped with casters for easy handling.


The user-friendly ergonomic control panel allows easy control of the whole device, requires no special skills, and is equipped with sockets designed for removal of full power delivered by the generator.



High-performance two-cylinder diesel generators from TM Könner & Söhnen are equipped with top-notch contact strips for connecting electrical cables, which allows removing the full power delivered by the unit.

The ATS (Automatic transfer switch) unit automatically starts the generator and transfers load to it when the main power supply is disconnected.

Gasoline and diesel generators with an electric starter are equipped with a universal 6-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.

– 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 KS ATS 4/63HD ATS unit is compatible with all Könner & Söhnen diesel generators with the abbreviation “ATSR” in the article number.

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.

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.
