FEATURES



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.



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. Digital voltage regulation at ±1%.



TEST CRITERIA:

√ PROTOTYPE TESTED √ NEMA MG1-22 EVALUATION

√ SYSTEM TORSIONALTESTED √ MOTOR STARTING ABILITY



SINGLE SOURCE SERVICE RESPONSE from Generac's extensive dealer

network provides parts and service know-how for the entire unit, from the engine

to the smallest electronic component.



TRUE POWER™ ELECTRICAL TECHNOLOGY: Superior 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 systems.



GENERAC TRANSFER SWITCHES: Long life and reliability are synonymous

with GENERAC POWER SYSTEMS. One reason for this confidence is that the

GENERAC product line includes its own transfer systems and controls for total

system compatibility.
