O 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 sbperior performance.
COOT QU►EfqfSF
Meets EPA Emission Regulations
22 & 27 kW are CA/MA emissions compliant
32 & 38 kW not for sale in CA / MA
O 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 °%.
O 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.
O TEST CRITERIA: O GENERAC TRANSFER SWITCHES. Long life and reliability are
%o PROTOTYPE TESTED v NEMA MG1-22 EVALUATION synonymous with GENERAC POWER SYSTEMS. One reason for this
SYSTEM TORSIONAL TESTED v MOTOR STARTING ABILITY confidence is that the GENERAC product line includes its own transfer
systems and controls for total system compatibility.
