📝 Description

This used Cummins Model DQDAA diesel generator set, serial number G200791229, offers 250 kW standby and 225 kW prime power output. It’s powered by a Cummins QSL9-G7 engine (SN: 74671938), rated at 464 HP at 1800 RPM, and is compliant with EPA Tier 3 emissions standards.

This generator features a 12-lead reconnectable alternator allowing configuration to 120/240V, 277/480V, and other voltages. A PMG (Permanent Magnet Generator) and an oversized alternator rated at 300 kW ensure excellent voltage stability and load response.

The unit includes a 400 Amp 100% rated main-line circuit breaker, PowerCommand 2100 digital control panel, battery charger, and coolant heater. Housed in a sound-attenuated enclosure rated for 150 MPH wind resistance, it also meets OSHPD seismic certification—ideal for installations in seismic zones.

A 720-gallon UL142 sub-base fuel tank with secondary containment supports extended run times. The unit was manufactured in 2020, has 89 runtime hours, and a load test is pending.
