Product Description

Product Description

30KW-400KW Diesel Generator Set

This diesel generator set is a robust, industrial-grade power solution with a power range of 30kW to 400kW, designed to deliver stable, continuous power for standby, prime, and emergency applications. It integrates a high-performance diesel engine, brushless alternator, and intelligent control system, complying with international standards (ISO 8528) for reliable operation across residential, commercial, industrial, and remote site scenarios.

Core Features
 
Wide Power Coverage: Available in 30kW, 50kW, 100kW, 150kW, 200kW, 250kW, 300kW, 350kW, and 400kW models to meet diverse load demands.
Stable Power Output: Equipped with a brushless, self-excited alternator for pure sine wave output, precise voltage/frequency regulation, and low waveform distortion, ensuring safe operation of sensitive electrical equipment.
Efficient & Durable Engine: Four-stroke, water-cooled diesel engine with turbocharging and intercooling; optimized combustion system for low fuel consumption (≈200–220g/kWh), low emissions, and long service life.
Intelligent Control System: AMF (Automatic Mains Failure) LCD control panel with real-time monitoring of voltage, current, frequency, water temperature, oil pressure, and fuel level; supports auto-start/stop, ATS integration, and fault self-diagnosis (overload, overheat, low oil pressure protection).
Flexible Configurations: Offered in open-frame, silent canopy (low noise, 65–75dB(A)), trailer-mounted, and containerized versions; compatible with 50Hz/60Hz and single/three-phase (220V/380V, 240V/480V) output.
Reliable Cooling & Protection: Efficient water cooling system for stable operation under high loads; IP23/IP45 protection for the alternator and control panel, suitable for harsh environments (dust, humidity, high temperature).
Easy Operation & Maintenance: User-friendly interface, quick-start function, and accessible service points; modular design reduces downtime for routine maintenance.
