The 48kW Industrial 1500 RPM diesel generator is a heavy-duty standby and prime power solution designed for factories, hospitals, data centers, commercial buildings, mining sites, and telecom facilities requiring reliable three-phase power. Rated at 48kW / 60kVA prime power (cosφ=0.8) with 1500 RPM operation, the lower engine speed reduces wear and extends service life compared to 3000 RPM portable units.
Powered by a four-cylinder, water-cooled, turbocharged diesel engine (Yuchai / Ricardo / Yangdong / Cummins-type options available depending on market), this 48kW diesel generator unit runs at a steady 1500 RPM delivering smooth, stable output. Paired with a 100% copper brushless alternator with AVR (Automatic Voltage Regulator), it produces clean, stable 220V/400V three-phase power with <±1% voltage regulation and low THD — safe for sensitive electronics, servers, and precision equipment.
The genset is ATS (Automatic Transfer Switch) compatible: when mains power fails, the ATS signals the generator to auto-start; when utility power returns, it shuts down automatically — ensuring seamless, unattended backup protection. A heavy-duty steel base frame with anti-vibration mounts, 24V electric start system with free-maintenance battery, and an 8–10 hour built-in fuel tank complete the package. Available in open-frame or weatherproof silent canopy (72–78 dBA @ 7m).
