Gas generator könner & söhnen KSB 2800C 2.5 kW with copper winding

The könner & söhnen KSB 2800C gas generator delivers single-phase AC power with a rated output of 2.5 kW. Its compact portable design integrates a gasoline engine with a copper-wound alternator to provide stable voltage under variable loads. The unit is intended for backup power, outdoor use and light-duty construction tasks where a reliable, transportable power source is required. Standard controls and built-in safety features allow straightforward operation and basic protection in everyday field conditions.

Advantages

Copper winding in the alternator improves electrical conductivity and heat resistance compared with cheaper winding materials, contributing to better voltage stability and longer lifespan under regular use. The generator’s compact footprint and integrated handle or frame make transport and storage easier. A rated 2.5 kW output supports a variety of single-phase loads, while standard safety and control elements allow quick startup, shutdown and basic overload or oil-level protection depending on the model configuration.

Suitable for

• Emergency household backup power for appliances and lighting
• Small construction and renovation sites powering hand tools and compressors
• Outdoor events, stalls or catering requiring temporary electric supply
• Recreational uses such as camping where single-phase power is needed

Key specifications

• Rated output: 2.5 kW (single-phase AC)
• Alternator winding: copper for improved conductivity and durability
• Fuel type: gasoline (petrol)
• Portable frame and compact dimensions for easier transport
• Standard control panel with start/stop and basic protective functions

How to use

Place the generator on a stable, level surface outdoors in a well-ventilated area, away from doors, windows and vents. Fill the fuel tank with the recommended gasoline and check engine oil before each use. Follow the manufacturer’s startup procedure: open the fuel valve if present, set the choke as required for cold start, and pull the recoil starter or use the electric starter if fitted. Connect single-phase appliances to the output sockets observing rated power limits and avoid simultaneous loads that exceed the rated output. After use, switch off connected devices, turn off the generator, close the fuel valve if applicable and allow the engine to cool before refuelling or transporting.

Usage recommendations

For safe and reliable operation, regularly inspect the copper-wound alternator and engine components, change engine oil per the service intervals, and use appropriate extension cords and grounding practices for temporary installations. Avoid running the generator indoors or in enclosed spaces. If powering sensitive electronics, use an appropriate voltage regulator or inverter/UPS to ensure clean power output.
