M1308 SERIES 435-545 kW / 400-475 kW FEATURES AND BENEFITS THE STATE-OF-THE ART IN MARINE EQUIPMENT The growing demands of the marine marketplace demand a big, robust power producer. As the world’s yachts grow more sophisticated, their power generation system must keep pace. Northern Lights generator sets are based on world-class components - including industrial strength base engines and generator ends. Our exclusive marinization process ensures reliable, clean power no matter what your vessel requires. ELECTRONIC SYSTEM PROFILER The M1308 series comes standard with a ComAp InteliGen NT marine panel for switchgear mounting which displays engine and AC data. The ECU that controls the electronic fuel injection provides a SAE J1939 data stream of engine information that can be shown on an optional system monitor panel. SUPERIOR PMG GENERATOR ENDS Northern Lights generator ends achieve ±0.5% voltage regulation. All have low temperature rise ratings to meet or exceed marine requirements. All M1308’s have Permanent Magnet Generators for 300% short circuit capability required for classed vessels. COMPREHENSIVE OPTIONS LIST Each option is designed to integrate into a total power system specifically designed for your vessel. Consider a high power PTO, world class sound enclosure or customizable control panel to make your generator set as unique as your boat. COMPLETE UNIT TESTING Northern Lights generator sets are thoroughly factory tested and go through a complete quality control program to ensure your satisfaction with the best built marine generator on the market today. COMPONENT SPECIFIC FEATURES ENGINE BLOCK • Vee-eight cylinder, four cycle, liquid cooled, overhead valve, marine diesels based on heavy-duty industrial engine blocks • Balanced, alloy steel crankshaft with hardened and polished bearing surfaces • High position alloy steel camshaft and pistons • Three ring aluminum alloy pistons with Ni-Resist insert for the top ring. Keystone piston ring reduces carbon buildup under light loads • Two gear-driven, counter-rotating balancing shafts for smooth operation • Eight groove poly-vee drive belt powers the alternator and freshwater pump • Replaceable, strength-optimized wet cylinder liners for long life and low rebuild costs FUEL SYSTEM • Electronically controlled fuel injection systems for low exhaust emissions and superior fuel economy • High torque at low revolution. (1800 or 1500 rpm) • Ring clamp fuel ﬁlter with air bleed and draiN • Diaphragm-type, mechanically driven fuel transfer pump with manual priming lever • Flexible fuel lines routed to fuel manifold on base frame for easy installation of vessel’s hard pipinG LUBRICATION SYSTEM • 500 hour oil change interval when fuel and oil requirements are met • Positive displacement gear-type oil pump • Full ﬂow, spin-on oil ﬁlter • Centrifugal oil cleaner reduces piston crown temperature for longer life • Freshwater, plate-type, full ﬂow oil cooler reduces heat and thermal breakdown of lube oil • Large capacity oil pan • Floating, cast aluminum, rocker cover traps valve noise and is a closed loop crankcase vent • Lube oil drain for easy changes AIR SYSTEM-TURBO AND AFTERCOOLER • Closed crankcase ventilation • Dry air ﬁlter silences intake noise • After-cooler with aircraft quality, 70/30 cupro-nickel, two pass element • Twin, isolated turbocharged for increased output. Fresh-water cooled turbine housings for safety COOLING SYSTEM • Freshwater cooling system with twin thermostats for quicker warm-ups • Duel heat exchanger with expansion tanks. Gear driven, flexible impeller seawater pump. Easy to clean, tube-type cupro-nickel heat exchanger • Cast iron expansion tank with brass ﬁller neck. Cast-iron exhaust manifold has double pass freshwater ﬂow for even temperature control, fast warm-up and no hot spots • Zinc anode electrolysis protection DC ELECTRICAL SYSTEM • SAE J1939 data stream available through a CAN bus plug for optional engine monitor. • Isolated ground 24 VDC system with circuit breaker, starter motor and battery charging alternator with regulator • Standard ComAp InteliGen NT marine panel for switchgear mounting displays engine and AC data. Upgradable with enclosure, synchronizing and paralleling capability • Low oil pressure and high coolant temperature safety shutdown system AC GENERATOR • Direct coupled, single bearing, 12 lead, reconnectable AC generator. Maintenance free brushless design • Generators meet or exceed class society standards. All have class H insulation, accessible diodes, oversized ball bearings, marine grade shafts and conservative 95°/50° heat rise ratings • Engines and generators are torsionally matched for long life • Automatic voltage regulator gives fast response to electrical load changes. Voltage is regulated to ±0.5% (one half of one percent) over the entire range from no load to full load • Isochronous electronic governor for 0% AC frequency droop • PMG (permanent magnet generator) to power AVR for 300% short circuit capability for classed vessels SPECIAL EQUIPMENT • Standard hydrolastic mounts isolate 98% of hull vibration • Welded steel base frame with drip pan. Easy to mount and keep clean • Belt guard protects operator even on sets in sound enclosures • Sparkling white IMRON® polyurethane paint for protection and visibility • Operator’s and parts manuals CLASSIFICATION STANDARDS •
