Northern Lights Model M673LD3 Marine Diesel Generator

Northern Lights Marine Diesel Generators

 5 kW - 60 Hz @ 1800 RPM
   Ask to see most companyís 5kW marine generator sets, and youíll likely see a light, fairly disposable machine, seemingly built as an afterthought.  Not Northern Lights. Our 5kW M673LD3 is built with the careful engineering and meticulously craftsmanship that has defined every Northern Lights product for over four decades.

   Northern Lights starts with a heavy duty base engine. Then our unique marinization process creates a machine specifically designed for the unforgiving rigors of the marine environment. Adding a sturdy generator end creates the most reliable, durable and simple to use marine power solution on the market.

   The M673LD3 is designed for unmatched reliability. By achieving 5 kilowatts at 1800, instead of 3600 rpm, the revolutions are cut in half. Piston and cylinder wear is minimized.
   The generatorís automatic voltage regulator (AVR) is powered by an auxiliary AC stator winding that isolates it from the main windings. This ensures that the AVR has clean power to provide excitation for faster load response. Whether running the refrigerator, air conditioner, or any other accessory, the M673LD3 can make power dips and surges a thing of the past.

   Comfort is always a consideration when it comes to Northern Lights generator power. The M673LD3 is built on a balanced three cylinder diesel. Four plateform isolation mounts reduce vibration transmission even further.

   The Sound Maze air intake system is another Northern Lights innovation developed with your comfort in mind. Air enters through a molded rubber hose and an acoustic dampening chamber. This allows for clear air flow, with a minimal noise signature. For even greater sound attenuation, your M673LD3 can be equipped with our state of the art sound enclosure.

   Because the M673LD3 meets all current USEPA Tire III emission standards, you can rest assured that your 5kW will be as clean as it is quiet and efficient.
