Hahn & Sohn HDE 15000EA3 diesel generator
A powerful diesel generator for single-phase and three-phase operation, designed for professional use, construction sites, and reliable backup power supply. It offers a maximum output of 11.0 kW at 230 V and up to 12.0 kW at 400 V, a robust open-frame design, electric starting, and stable output thanks to AVR regulation.
The Hahn & Sohn HDE 15000EA3 diesel generator is designed for demanding working conditions where reliability, power, and easy servicing are essential. The open-frame construction ensures high mechanical durability and easy access to all service points.
- The generator allows single-phase and three-phase operation with voltage switching 230 / 400 V. In single-phase operation (230 V), it delivers a maximum output of 11.0 kW (current 47.8 A), while in three-phase operation (400 V) it reaches up to 12.0 kW (current 17.3 A).
- Power is provided by a twin-cylinder, four-stroke, air-cooled diesel engine, optimized for long-term operation and low fuel consumption. Electric starting with a battery ensures convenient start-up, while AVR voltage regulation protects connected equipment from voltage fluctuations.
- Thanks to its performance, the HDE 15000EA3 is an ideal choice for construction sites, workshops, industrial operations, agriculture, and as a backup power source.
