Introduction

The GENLITEC POWER® GPC1250D5-SP and GPC1250S5-SP are 1250kVA Cummins diesel generator sets designed for reliable standby power applications in industrial, commercial, construction, mining, infrastructure and other critical power environments. The generator sets provide 1000kW/1250kVA standby power at 50Hz and 1500 RPM, with three-phase, four-wire electrical output.

Powered by the Cummins KTA38-G9 V-12 diesel engine, the GPC1250 series combines a high-capacity engine with a 1250kVA alternator. The 38-liter engine features turbocharged, water/air cooling, a Cummins PT Pump fuel system and an EFC electronic governor. At 1500 RPM, the KTA38-G9 provides 1089kW standby power, providing suitable engine capacity for the generator set's 1000kW/1250kVA standby rating.

The GPC1250D5-SP is the open type configuration, suitable for dedicated generator rooms and installations where ventilation and convenient maintenance are required. The GPC1250S5-SP is equipped with a sound-attenuated enclosure for outdoor installations and noise-sensitive environments. A 1700L fuel tank supports extended operation, while ATS, synchronization, remote monitoring and other configurations can be provided according to project requirements.
