INNOVATIVE DESIGN & PROTOTYPE TESTING are key
components of GENERAC'S success in "IMPROVING POWER
BY DESIGN." But it doesn't stop there. Total commitment to
component testing, reliability testing, environmental testing,
destruction and life testing, plus testing to applicable CSA, NEMA,
EGSA, and other standards, allows you to choose GENERAC
POWER SYSTEMS with the confidence that these systems will
provide superior performance.

TEST CRITERIA:

✓ PROTOTYPE TESTED
✓ SYSTEM TORSIONAL TESTED
✓ ELECTRO-MAGNETIC INTERFERENCE
✓ NEMA MG1 EVALUATION
✓ MOTOR STARTING ABILITY
✓ SHORT CIRCUIT TESTING
✓ UL COMPLIANCE AVAILABLE

n

SOLID-STATE, FREQUENCY COMPENSATED VOLTAGE
REGULATION. This state-of-the-art power maximizing regulation

system is standard on all Generac 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.

n

SINGLE SOURCE SERVICE RESPONSE from Generac's dealer
network provides parts and service know-how for the entire unit, from
the engine to the smallest electronic component. You are never on your
own when you own a GENERAC POWER SYSTEM.

n

ECONOMICAL DIESEL POWER. Low cost operation due to modern
diesel engine technology. Better fuel utilization plus lower cost per gallon
provide real savings.

n

LONGER ENGINE LIFE. Generac heavy-duty diesels provide long
and reliable operating life.

n

GENERAC TRANSFER SWITCHES, SWITCHGEAR AND
ACCESSORIES. Long life and reliability is synonymous with GENERAC

POWER SYSTEMS. One reason for this confidence is that the
GENERAC product line includes its own transfer systems, accessories,
switchgear and controls for total system compatibility.

GENERATOR FEATURES

■ Four pole, revolving field generator, directly connected to the
engine shaft through a heavy-duty, flexible disc for permanent
alignment.

■ Generator meets the temperature rise standards for class "F"
insulation as defined by NEMA MG1-32.6, while the insulation
system meets the requirements for the higher class "H" rating.

■ All prototype models have passed a three-phase symmetrical
short circuit test to assure system protection and reliability.

■ All prototype models are tested for motor starting ability by
measuring the instantaneous voltage dip with a waveform data
acquisition system.

■ All models utilize an advanced wire harness design for reliable
interconnection within the circuitry.

■ Magnetic circuit, including amortisseur windings, tooth and skewed
stator design, provides a minimal level of waveform distortion and
an electromagnetic interference level which meets accepted
requirements for standard AM radio, TV, and marine radio
telephone applications.

■ Voltage waveform deviation, total harmonic content of the AC
waveform, and T.I.F. (Telephone Influence Factor) have been
evaluated to acceptable standards in accordance with NEMA
MG1-32.

■ Alternator is self-ventilated and drip-proof constructed.

■ Fully life-tested protective systems, including "field circuit and

thermal overload protection" and optional main-line circuit breakers
capable of handling full output capacity.

■ System Torsional acceptability confirmed during Prototype Testing.
