Northern
Lights Model M673L3 Marine Diesel Generator |

|
The Northern Lights M673L3 is everything you
want in a generator set, and nothing you
don't. At 6.0 kW (5.0 kW for 50 Hz
applications), it's the right size -- big
enough to run many shipboard items and start
sizeable motors, yet small enough to fit
into tight engine rooms.
The M673L3 runs at 1800 rpm (60 Hz), not 3600 like sets built to a
slightly smaller envelope or to a slightly
smaller price. That slower speed means
quiet, smooth operation and much less stress
on the engine. During 2000 hours of
operation, the M673L2 will turn over 216
million fewer revolutions; its pistons will
travel 43,337 fewer miles; and its cylinders
will withstand 108 million fewer
detonations. Now, which engine do you think
will last longer? So do we.
Today's sophisticated on-board electronic equipment requires
"clean" power. Disruption or distortion of
that supply can play havoc with these
devices. With the M673L3, an additional
winding helps create and maintain a clean
sine wave. The independently powered
automatic voltage regulator further protects
electronic equipment while enabling large
electric motor starting. |

The M673L3's cast iron freshwater cooling
system and gear-driven seawater pump
minimize troublesome belts, hoses, and
gaskets. Polyurethane paint and a stainless
steel drip pan help prevent corrosion and
keep the engine room clean.
Four plateform isolation mounts reduce vibration, keeping the
on-board environment smooth and quiet. The
M673L3 is so quiet many owners opt to do
without a soundshield, but for maximum
attenuation there is a highly effective
optional powder coated aluminum soundshield.
Northern Lights are so efficient, they're
naturally environmentally friendly and meet
current emissions standards. This keeps
things clean, both on-board and for your
neighbors.The M673L3 meets the US EPA Tier
III emission requirements.
The M673L3's service points are all located on one side. Not only
can the unit be mounted close to a bulkhead,
but once in place, regular maintenance is
simple and convenient. Northern Lights'
unique D.C. logic system means that the
owner can troubleshoot and repair the D.C.
power system easily. A 30 amp A.C. circuit
breaker in the junction box gives short
circuit protection. Safety shutdowns for low
oil pressure, high water temperature, and
high exhaust temperature are standard.
In short, the M673L3 is what you'd expect from Northern Lights:
Everything that's important to keeping the
power on.
