• Genuine Cummins Industrial Diesel Engine
  Equipped with authentic Cummins 4-cylinder inline, water-cooled, turbocharged diesel engine (4BTA3.9-G2). It features mature industrial technology, strong power reserve, fast dynamic load response, low fuel consumption and low emissions. With global after-sales service network and universal spare parts supply, the engine supports long-term continuous operation with ultra-low failure rate.
• Original Leroy Somer French Premium Alternator
  Adopts world-famous French Leroy Somer pure copper brushless alternator, H-class insulation and IP23 protection grade. Equipped with high-precision AVR automatic voltage regulation system, it provides ultra-low distortion pure sine wave power. Compared with ordinary alternators, Leroy Somer alternator has stronger motor starting capability, better voltage stability and higher power efficiency, perfectly protecting high-precision medical, communication and industrial equipment.
• Heavy-Duty Low-Noise Silent Canopy
  The thickened galvanized steel canopy is treated with anti-rust and anti-corrosion paint, filled with high-density flame-retardant sound-absorbing cotton and matched with large industrial muffler and optimized air duct structure. The operating noise is controlled within 68–70dB(A) at 7 meters. The canopy integrates waterproof, dustproof and rainproof functions, adapting to long-term outdoor installation and urban environmental protection noise limit scenarios.
• Intelligent Full Protection Control System
  Configured with industrial-grade Smartgen or DeepSea intelligent digital controller. It monitors voltage, current, frequency, coolant temperature, oil pressure, rotation speed and running hours in real time. Built-in complete fault alarm and automatic shutdown protection system ensures safe and stable operation of the unit.
• Integrated Base & Vibration Reduction Structure
  Heavy-duty integral steel base with built-in fuel tank and high-strength rubber shock absorbers effectively reduces operation vibration and secondary noise. The integrated structure requires no complex foundation construction, convenient for transportation, hoisting and on-site installation.

• Reliable 24V Electric Start: Standard 24V DC electric starting system ensures fast and stable startup in low-temperature and harsh working environments.
• Full-Range Safety Protection: Automatic alarm and shutdown for low oil pressure, high water temperature, overload, over-voltage, under-voltage and overspeed faults to avoid unit damage.
• ATS Automatic Switching (Optional): Automatically starts when mains power fails and shuts down with delay after mains power recovery, realizing unattended intelligent emergency power supply.
• 24/7 Continuous Industrial Operation: Supports long-time stable prime power operation for off-grid factories, remote areas and continuous production projects.
• Remote Monitoring & Control (Optional): Supports remote real-time data viewing, start/stop operation and fault information push via mobile and computer terminals.
