Petrol generator könner & söhnen KS 7000E-3 ATS 230/400V, three-phase power output

Petrol generator könner & söhnen KS 7000E-3 ATS 230/400V, three-phase power output is a portable internal combustion generator designed to deliver three-phase 230/400 V power with an integrated automatic transfer switch (ATS). It provides temporary or emergency electrical supply for sites where mains power is unavailable or unreliable. The unit operates on petrol and is intended for use with industrial equipment, workshop tools and as backup power for small commercial or residential installations.

Advantages

The generator offers three-phase output suitable for motors and larger electrical loads, combined with ATS functionality for automatic switchover on mains failure. Petrol operation ensures wide refuelling availability and straightforward field servicing. The unit's design emphasizes portability and continuous power delivery under variable load conditions, while built-in protection and control features allow safer integration with on-site electrical systems.

Suitable for

• Construction sites powering three-phase tools and compressors
• Workshops running lathes, milling machines and welding equipment
• Small commercial facilities requiring backup power for essential loads
• Emergency household backup for heating systems, pumps and lighting

Key specifications

• Output voltage: three-phase 230/400 V compatible with industrial systems
• Fuel type: petrol for on-site refuelling and mobility
• Power delivery: designed for continuous and intermittent loads common in construction and workshops
• Automatic transfer switch (ATS): automatic mains failure detection and transfer to generator supply
• Portability: mobile design for relocation between sites
• Control features: integrated controls for start/stop and load management

How to use

Position the generator on stable, level ground in a well-ventilated outdoor area away from windows and doors. Fill the fuel tank with recommended petrol and check oil and coolant levels before starting. Connect loads according to the generator's three-phase output terminals or appropriate distribution panel, ensuring correct earthing and adherence to local electrical codes. If ATS is installed and configured with your mains supply, verify wiring and set the transfer parameters before enabling automatic mode. Start the engine using the recommended procedure in the user manual, allow the unit to reach operating speed and stable voltage, then progressively connect equipment to avoid sudden load spikes.

Usage recommendations

Regularly inspect fuel, oil and air filter condition, and perform scheduled maintenance to ensure reliable operation. Use appropriate protective devices (circuit breakers, residual-current devices) between the generator and connected equipment. When using the ATS feature, have a qualified electrician verify correct installation and settings to ensure safe automatic transfer between mains and generator supply.
