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 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 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.


"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.

Gasoline Generator KS 12-1E 1/3 ATSR

Gasoline generator KS 12-1E 1/3 ATSR is a unit with excellent operational characteristics, designed for backup power supply of facilities of various purposes. The device can be used during power outages, as well as installed in places where there's no possibility to connect to the stationary power network.

The generator is equipped with a capacious steel fuel tank (55 liters), so it can be refueled less often than many of its counterparts. The tank has an indicator to monitor the remaining fuel level.

This model of gasoline generator has the ability to connect the ATS unit (Automatic Transfer Switch). The unique phase switching system allows using the generator almost without loss of power in different operating modes:

• single-phase - 230V;
• three-phase - 400V.

To make the device control easier, engineers equipped it with an ergonomic control panel with an emergency stop button. The panel is completed with an LED display, which displays unit operation data in real time. The display allows you to monitor voltage, frequency, and working hours. The generator housing has outlets with automatic circuit breakers for connecting consumers.

The engine can be started in any convenient way:

• manual start;
• electric start;
• with the help of the ATS unit.

Long-term continuous operation of the equipment is ensured by the maximum quality of each system element. Thus, the device is equipped with an alternator with copper winding that can better withstand high loads.

The central element of the generator set is a powerful single-cylinder 4-stroke engine. An air cooling system is used to maintain the operating temperature of the engine. The engine installed on the KS 12-1E 1/3 ATSR model meets European standards, including environmental friendliness. The model is equipped with handles and transport wheels for easy movement.
