Cummins Diesel Generator Set
This series of generator sets is powered by H series, D series, E series, G-Serie, and W series power station diesel engines produced by Shanghai Diesel Engine Co., Ltd., equipped with branded generators. The unit has the characteristics of high voltage regulation accuracy, good dynamic performance, small voltage waveform distortion, high efficiency, reliable operation, long service life, and good economic performance. The unit is equipped with a complete set of maintenance free battery starting system. Users only need to inject oil and coolant, connect the negative switch, and then start the unit to output electricity, greatly improving the convenience of use.
