Engine-generator Könner & Söhnen KS 9200HDES-1/3 ATSR — 7000 W, 400 V, 11 L fuel, stainless steel, 4 wheels

The Könner & Söhnen KS 9200HDES-1/3 ATSR is a diesel engine-generator delivering a rated output of 7000 W at 400 V. Designed for mobile and stationary applications, it integrates an 11 L fuel tank, a stainless steel, noise-absorbing vandal-resistant housing and a 4-wheel transport set. The unit includes a VTS (Voltage Transfer Switch) system that allows quick switching between single-phase (230 V) and three-phase (400 V) operation with minimal loss of power, and an ATS (Automatic Transfer Switch) interface for automatic mains failure response. Compact in footprint and built with licensed Könner & Söhnen/DIMAX engines, the generator is intended to provide a stable AC supply across a range of operating conditions and comply with European emission standards.

Advantages

The VTS phase switching system provides flexibility to power both single-phase and three-phase loads from the same unit without needing two separate generators. Branded, licensed engines with a power reserve relative to the alternator ensure consistent voltage stability under varying loads, and engines are tested for long continuous operation. The all-season stainless steel housing is sound-absorbing and vandal-resistant, extending service life and protecting internal components. Integrated ATS compatibility and a pre-start heater support reliable automatic operation and cold-start capability. Four transport wheels and built-in handles allow easier relocation on sites where mobility is required.

Suitable for

• Construction sites requiring stable three-phase or single-phase power
• Backup power for small commercial premises and workshops
• Remote locations and outdoor events with portable power needs
• Equipment that requires automatic mains transfer via ATS

How to use

Place the generator on a firm, level surface with adequate clearance for ventilation and fuel filling. Use the VTS selector to choose single-phase (230 V) or three-phase (400 V) output according to the connected load requirements. Connect the load panels or ATS interface according to the electrical diagram supplied with the unit and ensure all protective devices and grounding are installed by a qualified electrician. For cold-weather starts, enable the pre-start heater before cranking the engine. Monitor fuel level, oil pressure, and instrument panel indicators during operation and follow the periodic maintenance schedule provided in the user manual.

Usage recommendations

To maintain reliable performance and compliance with emission standards, use low-sulfur diesel fuel, perform scheduled oil and filter changes, and run the unit periodically under load to prevent fuel system issues. Ensure installation and ATS wiring are carried out by a certified technician and observe local regulations for noise and emissions when operating in residential or regulated areas.
