| ˆ | 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 | ˆ | 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 electroniy torque-matching the surge loads to the engine. |
| ˆ | systems will provide superior performance. TEST CRITERIA: >PROTOTYPE TESTED | ˆ | 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. |
| >SYSTEM TORSIONAL TESTED >ELECTRO-MAGNETIC INTERFERENCE >NEMA MG1-22 EVALUATION | ˆ | 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. | |
| > MOTOR STARTING ABILITY |
Four pole, revolving field generator, directly connected to the engine shaft through a heavy-duty, flexible disc for permanent alignment.
Unit tested for motor starting ability by measuring instantaneous voltage dip with a wave form 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 balanced T.I.F. (Telephone Influence Factor) have been evaluated to acceptable standards in accordance with NEMA MG1-22.
Alternator is self-ventiliated and of drip-proof guarded construction.
Fully life-tested protective systems, including “field circuit and thermal overload protection” and standard main line circuit breakers capable of handling full output capacity.
System torsional acceptability confirmed during prototype testing.
