52kW 65KVA Cummins Industrial Generator Set QSB3.9-G2 is suitable for farms, small factories, workshops, irrigation stations, telecom rooms, commercial buildings, and site backup power where a compact 50Hz diesel generator set is required.
The TPD70C5-2 configuration provides 65 kVA / 52 kW prime power and 70 kVA / 56 kW standby power, giving about 7.7% standby kW reserve for motor starting, pump loads, compressor loads, and emergency backup demand.
The Cummins QSB3.9-G2 engine uses a 4-cylinder inline 3.9L platform, giving customers a practical balance between compact size, industrial durability, and serviceable power output in the 50kW generator set range.
Fuel consumption is 18 L/h at rated output, equal to about 0.346 L/kWh at 52kW load; for an 8-hour working shift, diesel planning is about 144 L, helping owners estimate daily operating cost before purchase.
The open type generator set footprint is about 1.52 m2 with 950 kg weight, making it practical for generator rooms, small equipment shelters, trailers, and compact industrial power systems.
The silent type generator set footprint is about 2.45 m2 with 1400 kg weight, giving customers a lower-noise Cummins generator set option for farms near residential areas, commercial backup power, outdoor standby power, and temporary sites.
Compared with selecting an 80KVA or 100KVA generator set for a 35kW to 48kW working load, this 65KVA generator set can reduce equipment size, installation space, and fuel storage pressure while still keeping standby reserve.
The recommended DSE7320 MKII DeepSea controller supports AMF auto-start, generator monitoring, shutdown protection, alarm display, and easier daily operation for customers who need automatic backup power during grid failure.
The 65kVA brushless alternator configuration with 400/230V, 3 phase 4 wire, 0.8 power factor, AVR voltage regulation, Class H insulation, and IP23 protection supports pumps, fans, lighting, HVAC, small production lines, and general industrial loads.
