Nengda-Cummins series diesel generator sets (20KW-1120KW)
Cummins Inc., a global power leader, is one of the biggest diesel genset manufacturer (＞50P) in the world. We specialized in produce and export Cummins diesel genset many years.
Major characterize:
1. The genset are complies with the standard of GB2820-91 national standard.
2. The engine and alternator are designed,developed and manufactured by Cummins
3. Cummins engine with advanced design,steady performance and long service time
4. The excitation system of alternator can improve the frequency steady ratio.
5. The low reactance design of alternator can help to reduce waveform distortion.
Cummins engine are four-stroke, 1500r.p.m, low oil consumption and auto adjustable.

Alternator:
Adopt world-famous brand: Stamford, leroysomer, engga and so on.
Control system:
The Deep Sea 501K control is an manual start control model which designed to start & stopthe genset by a key on the front panel, indicating the fault condition, shutting down the engine and indicating the engine failure by means of LED.
The model has the ability to monitor the following conditions:
a) Low oil pressire
b) High engine temperature
c) Auxiliaru shutdown
d) Overspeed
Each alarm channel has its own LED indicator and once activated no furture alarm conditions will be accepted.
