Denyo DCA-300SPM Diesel Generator – 300 kVA Power-SP Series, 3-Phase

The Denyo DCA-300SPM diesel generator from the Power-SP Series is designed for robust and continuous power generation, integrating a high-performance Mitsubishi Electric brushless alternator. Built to meet JEC-114-1979 standards, this three-phase generator delivers 250 kVA at 50 Hz and 300 kVA at 60 Hz with a selectable frequency mode and 220 V output. Its reliable SAS excitation system ensures steady voltage regulation, while the insulation Class F rating provides thermal resilience under demanding operations. Designed for outdoor and industrial environments, the DCA-300SPM includes a sound-attenuated enclosure and a water-cooled diesel engine, making it ideal for construction sites, remote facilities, and critical backup scenarios.
