Dongfeng Cummins Generator Set

Product Overview: Dongfeng Cummins Generator Set is a complete set of Dongfeng Cummins engine, which is widely used in hospitals, data centers, telecommunication base stations and other occasions that need standby power to ensure that the power supply can be started quickly when the power grid fails.

Unit composition: including diesel engine (with all accessories, three filters, electrical systems), brushless alternator, steel base, fan tank cooling system, 24V starter motor and charging motor, air filter, diesel filter, oil filter, self-starting control panel (a variety of protective functions), air protection switch, 24V starter batteries and battery cables, set of vibration absorbers, industrial efficient silencer Random technical documents (operating manual, factory test report, original quality documents, etc.). According to the user's requirements, it can also be equipped with ATS automatic switching cabinet, automatic parallel cabinet, 8-hour daily fuel tank, container-type generator set, low-noise generator set, trailer power station, remote microcomputer interface and so on.

Power range: The commonly used Dongfeng Cummins generator sets cover a power range of 20-320kW, with a variety of models to choose from, such as 4B3.9-G1, 4BT3.9-G1, 4BTA3.9-G2, 6BT5.9-G1, 6BTA5.9-G2, 6CTA8.3-G2, 6CTA8.3-G3, 6LTAA8.9-G2 and so on.

Performance characteristics: Dongfeng Cummins engine provides strong and stable power for the generator set. The generator set runs smoothly with low noise and good anti-vibration performance. There are various forms of automatic voltage regulation, such as thyristor, phase re-excitation, TD1 carbon resistance automatic voltage regulation, etc., which can ensure the stability of output voltage and meet the needs of different power equipment. It can start quickly, reach full power in a few seconds, and can be brought to full load within 1 minute in case of emergency, and the shutdown process is short, and it can be started and stopped frequently.
