Cummins QSK19 Series Diesel Generator Sets

Cummins Generator


Cummins Power Generation commercial generator sets are fully integrated power generation systems providing optimum performance, reliability and versatility for stationary standby and prime power applications.

  • Cummins® heavy-duty engine – Rugged 4-cycle, industrial diesel delivers reliable power, low emissions and fast response to load changes.
  • Alternator – Several alternator sizes offer selectable motor starting capability with low reactance 2/3 pitch windings, low waveform distortion with non-linear loads and fault clearing short-circuit capability.
  • Permanent magnet generator (PMG) – Offers enhanced motor starting and fault clearing short-circuit capability.
  • Control system – The PowerCommand® electronic control is standard equipment and provides total genset system integration including automatic remote starting/stopping, precise frequency and voltage regulation, alarm and status message display, AmpSentry™ protection, output metering, auto-shutdown at fault detection and NFPA 110 Level 1 compliance.
  • Cooling system – Standard integral set-mounted radiator system, designed and tested for rated ambient temperatures, simplifies facility design requirements for rejected heat.
  • Enclosures – Optional weather protective and sound attenuated enclosures are available.
  • NFPA – The genset accepts full rated load in a single step in accordance with NFPA 110 for Level 1 systems.
  • Warranty and service – Backed by a comprehensive warranty and worldwide distributor network.
