Sun Dynamac Diesel Generator 10 kW, Yanmar Engine, Made in Japan - TU12.5E

12.5KVA Diesel Generator (3-Phase)

Built for demanding industrial networks, the SUN-DYNAMAC TU-12.5E is a heavy-duty 3-Phase power plant delivering a true 10 kW (12.5 kVA). Unlike standard single-phase units, this generator is strictly engineered to drive high-voltage commercial machinery, supporting a flexible electrical spectrum from 200V to 480V. At the core of this system lies the legendary Yanmar TF-160E water-cooled engine. By utilizing an advanced V-belt transmission architecture, the engine runs at an unstressed 2400 RPM while the alternator spins at the required 3600 RPM. This crucial separation of rotational speeds drastically cuts down internal mechanical fatigue and achieves an outstanding fuel efficiency of just 2.5 liters per hour.

To protect sensitive operational equipment on site, voltage regulation is entirely automated. The brushless alternator features an integrated Automatic Voltage Regulator (AVR) that instantly corrects voltage fluctuations and strictly prevents electrical spikes. Furthermore, physical maintenance is virtually eliminated since there are no carbon brushes to wear out or replace. For extreme environments, a built-in thermal defense mechanism continuously monitors the system, instantly cutting off power generation if oil temperatures cross the 120°C critical threshold. Enclosed in a 100% Japanese-welded tubular steel frame, this unit is built to survive and perform in the harshest off-grid conditions.
