The Könner & Söhnen KS 9300DE-1/3 ATSR is an enclosed diesel generator with the manufacturer's VTS phase-switching system. It provides 6.0kW rated output at 230V single phase or 7.0kW rated output at 400V three phase, with electric starting, pre-start heating and a 6-pin connection for a compatible external automatic transfer switch. Its soundproof anti-vandal enclosure, four-wheel transport kit and copper-wound alternator make it a practical standby-power option for homes and small businesses.

Why choose the KS 9300DE-1/3 ATSR?
- Single- or three-phase supply: the VTS selector lets you choose 230V single-phase or 400V three-phase operation with high output available in either mode.
- Ready for automatic backup: a 6-pin connector supports automatic starting and stopping when the generator is paired with a compatible external ATS unit.
- Stable voltage: the intelligent AVR system helps maintain output voltage for compatible equipment.
- Enclosed Heavy Duty design: the soundproof anti-vandal enclosure helps reduce operating noise and protects internal components from accidental contact.
- Cold-start support: pre-start heating helps the diesel engine start more easily in low temperatures.
- Clear monitoring: the LED display shows voltage, frequency and accumulated operating hours.
- Easier positioning: four wheels and two handles help move the 168kg generator on suitable level surfaces.
Power, phase selection and standby use
Plan your continuous load
Use the rated output, not the short-term maximum, and allow for motor starting currents.
For prolonged operation, the manufacturer recommends no more than 80% of rated power: 4.8kW at 230V or 5.6kW at 400V.
Select one voltage mode
The 230V and 400V output circuits are not intended for simultaneous use. Stop and isolate the generator before changing the VTS selector.
In three-phase mode, distribute loads evenly; phase imbalance must not exceed 20%.
Professional ATS installation
Automatic mains-failure operation requires a compatible external ATS unit and suitable changeover, earthing and circuit protection.
Have fixed wiring designed and installed by a qualified electrician.

Manuals and downloads
Warranty
Manufacturer's warranty: 1 year or 1,000 operating hours, whichever comes first, from the date of purchase.
The warranty covers manufacturing defects, subject to the manufacturer's warranty conditions. Eligible faults may be repaired or the product replaced. Retain your proof of purchase and any completed warranty documentation supplied with the generator.
For help with a warranty claim, contact Energian with your order number, generator serial number and a description of the fault.
Frequently asked questions
Can I use the 230V and 400V outputs at the same time?
No. Select the required voltage mode using the VTS control and use only that output circuit. Stop and isolate the generator before changing modes.
Can it start automatically during a power cut?
Yes, when installed with compatible external ATS equipment. Fixed standby wiring and changeover protection must be designed and installed by a qualified electrician.
Is the stated maximum output suitable for continuous use?
No. Plan continuous loads around the rated output and allow extra capacity for starting currents. For prolonged operation, the manufacturer recommends no more than 80% of rated power.
Can I operate it in the rain?
No. The enclosure reduces noise and helps protect internal parts, but the IP23M rating does not make the generator weatherproof. Operate it outdoors in a dry, well-ventilated location that complies with the manual.
