Safety and Reliability Advantages of diesel DC generators:
1. Higher ignition point safety
Diesel fuel has a higher ignition point (220°C) and boiling point. It remains stable, non-volatile, and is less likely to ignite accidentally or explode, significantly enhancing fire safety.
2. Lower output voltage
The generator outputs low-voltage DC (max. 100V), far safer than traditional AC generators (220V-380V).
3. Ambient temperature monitoring & auto-shutdown
The DC genset is equipped with ambient temperature detection (configurable range: 50°C–90°C). It can automatically shut down when cabinet temperature reaches the set threshold.
4. Integrated automatic fire suppression
The cabinet contains fire extinguishing balls that activate instantly at 93°C to suppress internal fires.
5. Solenoid-controlled fuel shutoff
The diesel DC generator features an electromagnetic fuel valve that automatically closes upon engine shutdown. This eliminates manual fuel cutoff (required in AC generators), preventing continuous fuel supply during malfunctions or fires.
6. Fused signal wiring with short-circuit protection
All signal output lines of the diesel DC genset are fused. The genset can automatically halt operation during short circuits for system protection.
7. Flame-retardant wiring
All output cables use certified flame-retardant materials.
