Key Benefits

Delivers 1384 kW (1855 HP) from 50.3 L as a factory-rated assembly.
Turbocharged/Aftercooled induction with water cooled, 1 pump or 2 pumps/2 loops cooling keeps charge temperature under control in continuous duty.
Dry weight 5662 Kg and envelope 2978mm*2080mm*1780mm are published so the installation can be checked before ordering.
Starts without auxiliary aids down to -12℃.
Built on the KTA50 platform, a Cummins family with parts availability worldwide
Shipped from Shiyan, Hubei, China with export packing and full documentation

Application Scenarios

Prime mover for a new generator set build
Standby set engine replacement
Rental power fleet rebuild
Containerised power module

Who It Is For

Genset packagers matching an engine to an alternator
Rental power companies rebuilding sets between contracts
Industrial sites replacing the prime mover in an existing canopy
Telecom and data infrastructure contractors specifying standby power

Problems It Solves

An engine that does not hold speed under block load makes the whole set unusable.
Packagers lose weeks when the engine does not match the alternator and the base frame.
Standby sets sit idle for months and must still start and take load on demand.
Identifying the right KTA50-G9 variant from a serial number takes experience; MEP Power checks the configuration before quoting.

How It Compares

Compared with	What to consider
A rebuilt or used engine of the same rating	A rebuilt unit may show the same 1384 kW (1855 HP) on paper, but its running history is unknown and the warranty rarely covers the whole engine.
A larger engine in the same KTA50 range	Moving up a frame size adds weight, envelope and fuel burn; specify the next size up only if the duty cycle really needs the headroom.
A non-Cummins engine of similar output	Parts and service for Cummins families are available in most markets, which matters more over ten years than the purchase price on day one.
