Description

Cummins 500 DF EC Diesel Generator – 500 kVA, Brushless Alternator with AVR, 3-Phase

The Cummins 500 DF EC diesel generator is engineered for demanding industrial and standby power applications, offering 500 kVA (400 kW) output at a power factor of 0.8 lagging. Built with a robust HCI534D1 alternator core, this 3-phase generator delivers 400 V at 760 A with tight voltage regulation of ±1% through an automatic voltage regulator (AVR) system. The brushless excitation system ensures long-term reliability and maintenance-free operation, while its Series Star stator connection and insulation Class H enable thermal durability in high-load conditions. Operating at 1500 RPM and 50 Hz, this generator is housed in an IP23-rated enclosure, suitable for controlled indoor environments or protected outdoor installations.
