harmonics and sine wave form produce less
than 5% Total Harmonic Distortion for utility
quality power. This allows confident operation of
sensitive electronic equipment and micro-chip
based appliances, such as variable speed HVAC.

Test Criteria:
• Prototype Tested Nema Mg1-22 Evaluation
•
System Torsional Tested
•
Motor Starting Ability
•
Solid-state, frequency compensated voltage
regulation. This state-of-the-art power maximizing regulation system is standard on
all Eaton models. It provides optimized fast
response to changing load conditions and maximum motor starting capability by electronically
torque-matching the surge loads to the engine.
•
Single source service response from the industry’s best dealer network provides parts and
service know-how for the entire unit.

Benefits
•
Maximizes engine “breathing” for increased fuel efficiency. Plateau honed cylinder walls and plasma moly
rings help engine run cooler, reducing oil consumption. Because heat is the primary cause of engine wear,
the OHVI has a significantly longer life than competitive engines.
•
Rigid construction and added durability provide long engine life.
•
These features combine to assure smooth, quick starting every time.
•
Superior lubrication to all vital bearings means better performance, less maintenance and significantly
longer engine life. Now featuring a 2 year/200 hour oil change interval.
•
Superior shutdown protection prevents catastrophic engine damage due to low oil.
•
Prevents damage due to overheating.
•
Allows for smaller, light weight unit that operates 25% more efficiently than a revolving armature
generator.
•
Produces a smooth output waveform for compatibility with electronic equipment.
•
Maximizes motor starting capability.
•
Regulates the output voltage to ±2% prevents damaging voltage spikes.
•

Controls
•
Manual/Auto/Off switch
•
Selects the operating mode.
•
Utility voltage sensing
•
Constantly monitors utility voltage, setpoints 65% dropout, 75% pick-up, of standard voltage.
•
Utility interrupt delay
•
Prevents nuisance start-ups of the engine, adjustable 10-30 seconds.
•
Engine warm-up
•
Ensures engine is ready to assume the load, setpoint approximately 10 seconds.
•
Engine cool-down
•
Allows engine to cool prior to shutdown, setpoint approximately 1 minute.
•
Seven day exerciser
•
Operates engine to prevent oil seal drying and damage between power outages.
•
Timed Trickle Battery charger
•
Maintains battery charge level to insure starting.
•
Main Line Circuit Breaker
•
Protects generator from overload.
•
Electronic governor
•
Maintains constant 60 Hz frequency.
•
Weather protective enclosure
•
•
Enclosed critical grade muffler
Ensures protection against mother nature. Hinged key locking roof panel for security. Lift-out front for easy
access to all routine maintenance items. Electrostatically applied textured epoxy paint for added durability.
•
Small, compact, attractive
•
Quiet, critical grade muffler is mounted inside the unit to prevent injuries.
•
Makes for an easy, eye appealing installation.
