KS 12-1E 1/3 ATSR gasoline generator is maximum power with one cylinder!
The generator is suitable for connecting an ATS unit and has a unique VTS phase switching system, which allows using the generator both in single-phase mode (230 V) and three-phase mode (400 V) without loss of power. A user-friendly ergonomic control panel with a generator emergency stop button and a multifunction LED display allows monitoring of the generator operation: voltage, frequency, operating hours, as well as oil level. This model is equipped with sockets for full power removal by the generator. The sockets are equipped with fuses and completed with suitable plugs. The high-capacity 55 l fuel tank ensures lengthy and continuous operation.



Powerful and reliable 1-cylinders air-cooled engine (18.5 HP), high-performance and costeffective, and conform to European quality standards (including exhaust emissions and noise). Each engine has a corporate K&S stamp and an individual serial number in order to ensure the quality control of manufacture and after-sales service.


Easy start system allows you to start the engine quickly and to do this without much effort. More powerful models are additionally equipped with an electric start system.



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 and modern LED- display (hour meter, frequency, voltage, oil alarm). Panel is equipped with engine emergency switc.

8-pin ATS output

The generator is suitable for connecting the ATS (Automatic Transfer Switch) system.

The ATS output features a universal 8-pin connector with no system choice limitation for the automatic transfer switch.

The KS ATS 4/32-12 ATS unit is compatible with KS 12-1E ATSR and KS 12-1E 1/3 ATSR gasoline generators from Könner & Söhnen.

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.


TM Könner & Söhnen generators are equipped with a high-end synchronous alternator with 100% copper winding. It is only the copper winding that can withstand maximum loads without any damage to ensure long-term reliable operation of the generator set.

Steel tank


“Könner & Söhnen” generators are equipped with an enlarged steel fuel tank (55 l), which extends the generator’s operating time without refueling. The fuel level indicator is located on the tank for ease of use.
