Cummins - Model D1703-M Series Engine - Diesel Generator Set

• Kubota heavy-duty engine - Rugged 4- cycle, liquid-cooled, industrial diesel delivers reliable power, low emissions and fast response to load changes.
• Alternator - Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings, low waveform distortion with non-linear loads and fault clearing short-circuit capability.
• Control system - The PowerCommand 1.1 electronic control is standard equipment and provides total genset system integration including automatic remote starting/stopping, precise frequency and voltage regulation, alarm and status message display, output metering, auto-shutdown at fault detection and NFPA 110 Level 1 compliance.
• Cooling system - Standard integral set-mounted radiator system, designed and tested for rated ambient temperatures, simplifies facility design requirements for rejected heat.
• Enclosures - Optional weather protective and sound attenuated enclosures are available.
• Fuel Tanks - Dual wall sub-base fuel tanks are also available.
• NFPA - The genset accepts full rated load in a single step in accordance with NFPA 110 for Level 1 systems.
• Warranty and service - Backed by a comprehensive warranty and worldwide distributor network.
