MDKDT/U/S 22.5/27/29 kW

Product catalog summary

Product Overview: The Onan Marine QD generator series offers power outputs ranging from 22.5 to 29 kW. It is designed for marine applications and features both housed and unhoused configurations with dimensions and weights varying slightly based on the configuration.

Specifications: The generators are powered by a 4-cycle, water-cooled Kubota marine diesel engine with a displacement of 3318 cm³. The fuel system includes an electric fuel transfer pump with a maximum lift of 1.22 meters. The cooling system is freshwater-based with a heat exchanger and a coolant capacity of 13.7 liters. The lubrication system includes a marine-grade oil pan with an 11.4-liter capacity.

Power Ratings: The generators operate at different power ratings and phases, with models like MDKDT, MDKDU, and MDKDS offering various kWe and kVa outputs at 50 or 60 Hz. Fuel consumption varies with load, and all models comply with EPA Tier 3 emissions standards.

Alternator Details: The Onan alternator is brushless with a revolving field and features a solid-state voltage regulator. It is designed to minimize voltage harmonics and is protected against corrosion.

Performance: The generator set offers isochronous frequency regulation with steady-state frequency and voltage deviations of less than 1% per ISO 8528-5 standards. It supports NEMA 2000 and SAE J-1939 CAN protocols for monitoring and diagnostics.

Standards and Testing: The generator set is compliant with NMMA and ABYC standards and is manufactured in ISO 9001 certified facilities. It also has Lloyd’s Register Type Approval for marine applications.

Warranty: Cummins provides a limited warranty covering most components for the first two years, with parts and labor coverage extending to major components for up to five years. An optional extended warranty is available.
