  • KOHLER Co. provides one-source responsibility for the generating system and accessories.
  • The generator set and its components are prototype-tested, factory-built, and production-tested.
  • The 60 Hz generator set offers a UL 2200 listing.
  • The generator set accepts rated load in one step.
  • The 60 Hz generator set meets NFPA 110, Level 1, when equipped with the necessary accessories and installed per NFPA standards.
  • The generator set complies with ISO 8528-5, Class G2, requirements for transient performance in all generator set configurations. Select the Decision-Maker(R) 550 controller for improved voltage regulation and ISO 8528-5, Class G3, compliance.
  • The 60 Hz generator set engine is certified by the Environmental Protection Agency (EPA) to conform to Tier 3 nonroad emissions regulations.
  • A one-year limited warranty covers all systems and components. Two-, five-, and ten-year extended warranties are also available.

Alternator features:
  • KOHLER's unique Fast-Response(TM) II excitation system delivers excellent voltage response and short circuit capability using a permanent magnet (PM)-excited alternator.
  • The brushless, rotating-field alternator has broad range reconnectability.
  • NEMA MG1, IEEE, and ANSI standards compliance for temperature rise and motor starting.
  • Sustained short-circuit current of up to 300% of the rated current for up to 10 seconds.
  • Sustained short-circuit current enabling downstream circuit breakers to trip without collapsing the alternator field.
  • Self-ventilated and drip-proof construction.
  • Vacuum-impregnated windings with fungus-resistant epoxy varnish for dependability and long life.
  • Superior voltage waveform from a two-thirds pitch stator and skewed rotor.
  • Fast-Response(TM) II brushless alternator with brushless exciter for excellent load response.

Other features:
  • Controllers are available for all applications.
  • The low coolant level shutdown prevents overheating (standard on radiator models only).
  • Integral vibration isolation eliminates the need for under-unit vibration spring isolators.
