Cummins QSL9 Series Diesel Generator Sets

Overview

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. Power ratings range from 220 kW (275 kVA) to 300 kW (375 kVA).

  • 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.
  • Fuel tanks – Dual wall sub-base fuel tanks are also available.
  • NFPA – The genset accepts full rated load in a single step in accordance with NFPA 110 for Level 1 systems.
