Cummins PowerMax KTA50G3+ 1250kVA Containerized Diesel Generator

Containerized diesel power generation package built around a Cummins KTA50G3+ engine, a 4-cycle, 60-degree Vee, 16-cylinder configuration, paired with a CGT PE734C2 alternator regulated by an MX321 AVR at ±0.5% regulation. Speed control is managed by a GAC ESD5520 governor controller with Cummins EFC governor actuator, while power control and protection functions are handled by a Deif PPU2 system with custom firmware covering baseload, peak lopping, load share/island power management, droop control, and comprehensive protection functions including overcurrent, overload, reverse power and excitation loss, under/overvoltage, under/overfrequency, unbalanced voltage/current, ROCOF and vector shift, low oil pressure, high coolant temperature, low coolant pressure, fuel spillage and high fuel level monitoring, ESD/intertrip, and alternator RTD monitoring, with G59-capable grid connection protection. The unit is housed in a custom-built 20ft ISO container divided into two compartments: the larger compartment holds the diesel generator set, fuel tank, and controls, and the smaller compartment houses the large-surface-area cooling radiator and low-speed roof-mounted fan. Generator compartment walls are fully lined with non-combustible mineral fibre acoustic linings retained by galvanised perforated steel sheet, with noise-attenuated ventilation air inlets and outlets. Safety systems include bunded spill containment, fluid spillage alarm linked to engine shutdown, and recessed emergency stop buttons at container access points. Auto-paralleling capability is provided via Deif PPU2 with frequency/voltage matching and auto-synchronization. The container is CSC certified with corner castings, 2 lockable doors, and 4 internal lights. Used in power generation, standby and prime power applications, construction sites, and industrial facilities requiring containerized diesel-fueled electrical power with paralleling and load management capability.

Suitable for

Diesel generator set, containerized power generation, standby power generation, prime power supply, industrial power generation, Cummins diesel engine, construction site power, load management power system, auto-paralleling generator
