60 Hz / 1800 RPM

5 kW

50 Hz / 1500 RPM The ideal 6kW generator set is small and lightweight. The M673L2 certainly qualifies. But it stands apart through its remarkable long-life reliability. The reason? The M673L2 runs at 1800 rpm (1500 rpm for 50 Hz), instead of 3600 rpm. Consider that during only 2000 hours of operation the 1800 rpm M673L2 will turn 216 million fewer revolutions than a 3600 rpm set. Its pistons will travel 38,522 fewer miles. Its cylinders will withstand 108 million fewer detonations. Which engine do you think will give more years of reliable service? We couldn’t agree more. The M673L2 has a balanced Lugger three cylinder diesel instead of a rough two banger. Four plateform isolation mounts reduce vibration transmission even more. For maximum comfort afloat the new M673L2 has a Sound Maze air intake system. Air enters through a molded rubber hose and an acoustic dampening chamber. Air goes in but much less noise gets out. For maximum sound attenuation, specify a sound enclosure. It is only 32.5 inches long and has powder-coated aluminum panels with trigger latches for easy service access. The generator ’s automatic voltage regulator is powered by an auxiliary AC stator winding that isolates it from the main windings. The AVR always has clean power to provide excitation for faster load response and better motor starting. Your air conditioner and other motor driven equipment will love being matched with the 673. A 30 amp AC circuit breaker in the junction box protects your wiring. Safety shutdowns for low oil pressure, high coolant temperature and high exhaust temperature protect your engine. The M673L2 meets US EPA Tier II emission standards. You, your moorage neighbors and the environment will all benefit. 1800 rpm reliability, low emissions, quiet operation and strong motor starting. Good things do come in small packages.

Ask to see most company’s 5kW marine generator sets, and you’ll likely see a light, fairly disposable machine, seemingly built as an afterthought. Not Northern Lights. Our 5kW M673LD2 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 M673LD2 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 generator ’s 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 M673LD2 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 M673LD2 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 M673LD2 can be equipped with our state of the art sound enclosure. Because the M673LD2 meets all current USEPA emission standards, you can rest assured that your 5kW will be as clean as it is quiet and efficient.

Northern Lights strong reputation for reliability and simplicity is evident on the 8 kW, M753W2. Year in, year out, this bulletproof workhorse has been a favorite for yachtsmen and commercial operators for both repowers and new vessel construction. It has constantly been improved and we are now proud to introduce the newest version; the M753W2. The set is still powered by a 58 cubic inch Lugger diesel which runs at 1800 rpm instead of 3600. Lower speed promotes engine life by reducing internal stresses. The engine has a mono-component, cast iron, freshwater cooling system to reduce troublesome gaskets and hoses. Being a three cylinder, the engine is balanced for smooth operation. This along with vibration isolation mounts, intake silencer system and cast valve cover make the M753W2 remarkably smooth and quiet with or without a sound enclosure. The M753W2 is simple to maintain. All service points are on one side within easy reach. The seawater pump’s location makes impeller changes a snap and it is gear-driven, so there are no belts to fray and break. The engine’s DC electrical system and safety shutdowns use reliable relays instead of delicate, unrepairable printed circuit boards. If a failure should occur you simply plug in a new, inexpensive relay. The M753W2 meets US EPA Tier II emissions standards. You, the environment and your moorage neighbors will all benefit.

Featuring new W-Series generator The new W-Series generator end is a major step in our constant quest to give you the best generator set on the market. It features an auxiliary stator winding that supplies separate and stable power to the Automatic Voltage Regulator (AVR). The results are impressive: • Classification society compliance. • Real 300% short circuit capability. • Improved AC circuit breaker performance. See your dealer for more information.

• Beltguard for safety.

• Plateform vibration mounts for smooth operation.

• 12 volt DC starter and battery charging alternator.

50 Hz / 1500 RPM These are the powerhouses that go in vessels that need continuous AC power to operate. Unfortunately, some 20 kW machines have small displacement, light duty diesels that can’t stand up to heavy use. Some even need turbochargers to compensate for their small displacement. The M844LW2 is different. Powered by a naturally aspirated, four cylinder, 2.2 liter (135 cid) Lugger diesel, this set has the low end torque needed to start bigger electric motors without breaking a sweat. The M844LW2 meets US EPA Tier II emission standards to protect the environment you enjoy. Vibration isolation mounts, air intake silencer and cast manifolds make the set remarkably smooth and quiet. A high attenuation sound enclosure is optional. Northern Lights generator sets are simple to operate and maintain. A 20 foot wire harness and control panel lets you operate it from your boat’s bridge. The engine’s DC electrical system uses reliable relays instead of delicate printed circuit boards. If a failure should occur, you can simply plug in an inexpensive relay. All service points are on one side within easy reach. The sea water pump is up front for easy impeller changes. Need hydraulic power? Add an optional electric clutch front PTO. At the touch of a button you have power for your bowthruster and winches without starting your main Front PTO engine.

The M864W combines ample power, long life features, and low emissions owners expect from a Northern Lights. Exceptionally smooth, quiet and clean, it makes life aboard comfortable while protecting the environment. The 2.5 liter Lugger diesel has been designed for clean exhaust and meets the US EPA Tier II emission requirements. Noise is reduced at the design stage with several features. A laminated oil pan and an isolated rocker arm cover contain the noise at its source. A noise maze air intake silencer lowers noise while isolation mounts limit transmission of vibration to the vessel. For even more comfort specify a super attenuated, powder coated sound enclosure. The M864W is easy to live with and to service. Single side servicing, spin-on oil and fuel filters, washable air filter, two oil fills and a sea water pump you can actually reach make it a skipper’s dream. The relay based DC electrical system has no printed circuit board so you’ll never have to make the “motherboard” of all parts purchases. The M864W is available with a front PTO (power take off) and electric clutch. With the touch of a button you have up to 37 Horsepower at 1800 rpm for powering hydraulic accessories such as bow thrusters, Front PTO roller furling, anchor winches and deck gear.

A big power producer in a little package, the new Northern Lights M944W is ideal for the boater who expects unqualified excellence from his generator set without sacrificing valuable engine room space. Cranking out 30 kW at 60 Hz (1800 rpm), the M944W2 is intended for long life at full load. At more then 3.33 liters, this four cylinder dynamo has the displacement (203 cid) to shoulder the large loads. The generator is driven by a reliable Lugger engine, drawing its strength from an industrial block designed for 2500 max rpm; not the 3600 rpm automotive engine common in the industry. That is the reason that the M944W hits the top of its torque curve at 1800 rpm instead of sliding down the back of it. The block is impressive, but what makes the M944W so well adapted for the rigors of at-sea use is Northern Lights’ exclusive marinization package. From the cupro-nickle heat exchanger to the bronze/stainless gear driven seawater pump, no detail has been overlooked in engineering a superior marine product. The freshwater cooled exhaust manifold is sturdy cast iron with no dry risers. The M944W features Northern Lights’ revolutionary W-Series generator end for clean AC output and real short circuit protection. The air filter is cast aluminum for quiet operation. Producing AC is hardly the M944W’s only trick. Add a 90 amp DC alternator and you’ll never run out of battery power again. Add a front PTO with an electric clutch for hydraulic power and drive your winches, bow thrusters or deck gear at the touch of Front PTO a button. Reliable, durable, simple to use, and maintain. For nearly 50 years, this has been the hallmark of Northern Lights products. The tradition of excellence continues with the M944W.

THE W-SERIES GENERATORS GIVE YOU REAL WORLD 300% CAPABILITY. Auxiliary winding for AVR. The new W-Series generators are a major step forward in our constant quest to give you the best generator set on the market. W-Series generators feature an auxiliary stator winding that supplies separate and stable power to the Automatic Voltage Regulator (AVR). The results are impressive: • Classification society compliance. • Real 300% short circuit capability • Improved AC circuit breaker performance. • No increase in size. Basic generator set operation It’s important to understand how most generator sets make power to fully appreciate the advantages of the new W-Series sets. An engine turns the AC generator’s rotor inside of a stationary stator at a given RPM. The rotating magnetic fields between the rotor and stator produce AC electricity. Some of this electricity is used to power the set’s automatic voltage regulator (AVR). The regulator senses load changes as you turn electrical appliances on and off. It then sends DC electrical power to the generator’s exciter windings. The exciter increases or decreases the field of the main rotor to make the power needed by the load. Clean power requirements. The AVR needs stable power from the main rotor to do its job well. Some components, such as battery chargers, variable frequency drives and other nonlinear loads can actually corrupt the generator’s output waveform. Starting large electric motors can also cause problems. When turned off, a motor is in a dead rotor condition. The current needed to overcome the inertia of the dead rotor and start the motor is called “inrush”. Inrush can often be many times the power needed to run Ordinary generator AVR powered by corruptable main AC output. AC to AVR buss Engine Main rotor

Exciter rotor & stator

Stator

the motor after it is started. This is why some generator sets slow and the lights dim when a motor is turned on. This is called voltage dip. An AVR being powered by corrupted power or voltage that “dips, surges and sags” can become part of a cascade of problems. Weakened by a bad power supply the AVR doesn’t react well to new load demands. It’s Dealer

power to the exciter degrades. Less excitation means less power from the main output further degrading the power supply to the AVR...a cascade or loop effect is created. A main line short circuit is the ultimate power supply problem for the AVR. The power drawn by the short leaves no electricity to power the AVR so it stops powering the excitor windings. In milliseconds the magnetic field between the stator and rotor collapses. No electricity is being made. You are now standing in the dark while the generator set is still running and the mainline circuit breaker has not tripped. Why didn’t the circuit breaker trip? If you have a mild short circuit, the breaker may have time to respond and it may trip. However, when a dead short occurs, the field collapses so fast that there isn’t time for the circuit breaker to respond. That is why the circuit breaker on your generator set has probably never tripped. Why do some generator manufacturers put circuit breakers on their sets? Because industry councils recommend they do it. The manufacturer follows the guidelines even though they know it is of little practical use. W-Series auxiliary winding supplies clean power to AVR AVR Engine

Stator Main rotor Stator

Exciter rotor & stator AC to buss

W Series sends clean power to the AVR To solve these problems the W-Series generators have a special auxiliary winding to power the AVR. The winding is completely separate from the main stator windings and is not affected by load changes and power corruption. It’s only job is to provide stable power to the AVR. This greatly enhances its ability to regulate the main output power. The AVR is always ready to respond to the large load increase needed to start motors. Even under a direct short circuit condition the AVR will continue to provide excitation support until the circuit breaker trips breaking the connection. This is true, real world 300% capability. No size increase. W-Series generators are the same compact size as the K-Series they replace. Boatbuilders will not need to modify their engine rooms to accommodate the new sets.

Classification Requirements Marine classification societies set standards for equipment used on vessels. Only the largest vessels are built to “Class”, having been built, inspected and approved to have met the classification standards. Many owners of vessels do not need this level of quality assurance. They do, however, want the best equipment, so they specify generator sets that have a society Type Approval. This increases the value of their vessel and their peace of mind. Northern Lights generator sets from 4.5 to 33 kW have proudly held a Lloyds’ Type Approval since 1999. “8.4.5 Generators and their voltage regulation systems are to be capable of maintaining, without damage, under steady state short circuit conditions a current of at least three times the full load rated current for a duration of at least two seconds...” Lloyd’s Register of Shipping Rules and regulations for the classification of special service craft, July 2002

300% short circuit capability Marine classification societies including Lloyds, ABS, DNV, BV, and the USCG require that the generator on a boat built to “class” have 300% short circuit capability. This means the generator end can withstand a short circuit that increases its amperage output three times its rated capacity for a specified period of seconds without the magnetic field collapsing and without sustaining damage. Want true 300% capability? In the past you had to specify a permanent magnet generator (PMG) or a current boost system. These work well on larger sets. Large Northern Lights sets have PMGs as standard or optional equipment. Now, the W-Series offers true 300% short circuit capability to owners of sets from 8 to 33 kW. These sets will meet the requirements for owners who are building “Class” vessels. Don’t be confused by “capability” claims. If a generator manufacturer claims 300% short circuit “capability” ask what that means. Will their set actually produce 300% of rated current until the breaker responds? Or is it a theoretical “capability” meaning that the generator would not be damaged if it produced 300%, which it can’t, because the magnetic field collapses first. This is akin to saying; “Yes, our car would pass a crash test, if we could get it to run long enough to hit the wall” Northern Lights W-Series The best just keeps getting better. See your Northern Lights dealer. They have the new W-Series set that is right for your vessel.

W-Series

The new Northern Lights W-Series generators First the K, Now the W.

The Skewed Stator.

In 1998 we introduced the K-Series which increased generator performance without increasing size. Six years of duty have shown the K generators to be nearly bullet proof. The new W-Series is based on this proven design and is the next step in the ongoing development of superior generator ends from Northern Lights. W-Series will be phased into production on all marine and industrial Northern Lights, 60 and 50 Hz sets, 8 to 33 kW.

The stator is hand wound by experienced craftsmen. The winder’s eyes are a constant quality control check. The skewed design (angled grooves) makes electricity with a clean, symmetrical wave form that electrical equipment needs. The stator is encased in a strong, rolled steel generator frame which has machined ends to mate with the cast iron bearing housing and SAE housing adapter.

Auxiliary Winding To Power The AVR.

An auxiliary stator winding makes dedicated power for the new DST-1002FAK automatic voltage regulator. This gives you several advantages. • Classification society compliance. • Real 300% short circuit capability • Improved AC breaker performance. See the back of this page for a detailed explanation of this feature. Automatic Voltage Regulator = 1% RMS.

The solid state AVR produces clean 1% RMS voltage regulation from no load to full load. This protects electronics and extends motor life. Compare this to ± 1.5% or ±5% of competitive generators. The AVR also allows the generator to produce 50 or 60 hertz power at 100 or 200 class voltage. Boatbuilders: you use one set for domestic and foreign markets. ±

Hot Dripped Rotor.

The rotor is made up of a shaft, large sealed bearing (A), an easily A B C D accessible rotating rectifier (B), a large diameter exciter rotor (C) and main rotor (D). The rotor assembly is slowly hot dripped with high quality, Class “H” epoxy insulation for protection against the marine environment.

1 Phase Standard – 3 Optional.

Standard PX-300W generators are 1 phase, 4 wire. If you need 3 phase power, order your set with an optional 12 wire generator end.

Bearing Housing & Exciter Stator.

The bearing housing is cast iron, not aluminum. Iron is stronger, resists electrolysis and has a thermal expansion rate that more closely matches the bearing on the rotor. This helps to prevent “spun bearing” failures that plague aluminum housings. We bolt the exciter stator in the removable bearing housing for easy access. Some generators have the exciter welded to the frame making it unreplaceable.

The Leader Uses Leads.

Some manufacturers use the solid copper magnet wire to connect the set to the load. “Leadless” design is cheaper but prone to failure from vibration. We use multi-strand wire leads with high temperature insulation. These leads go to a terminal strip in the junction box for easy connection to your AC electrical system. Paralleling the big boys.

The M844LW2, M864W and M984W models have 2/3 winding pitch so they can be easily paralleled with the larger Northern Lights sets. This makes them part of your total power solution.

A look inside the PX-300W generators from 8 to 33 kW.

High Copper Content.

One thing we didn’t change was the amount of copper in the generator. High copper content gives higher performance. • Better generator efficiency. • More motor starting capability. • Longer life. The PX-300Ws have a conservative 95°C temperature rise rating at 50°C ambient air. Compare this to the 105/40 or even 125/50 ratings used by some manufacturers.
