CUMMINS AC1100 Diesel Generator – 50Hz

AKSA AC1100 diesel generator set rated at 1100 kVA / 880 kW standby and 1000 kVA / 800 kW prime. Powered by a Cummins QST30G4 diesel engine, this 400/230V, 50Hz, 3-phase generator is designed for reliable high-capacity standby and prime power applications, with DSE7320 control, brushless alternator, integrated fuel tank, and optional sound-attenuated canopy configuration.

Brand: CUMMINS

Product Overview

The AKSA AC1100 is a heavy-duty diesel generating set built for dependable standby and prime power use across commercial, industrial, infrastructure, construction, data centre, agricultural, and backup power applications. It delivers 1100 kVA / 880 kW standby power and 1000 kVA / 800 kW prime power, making it suitable for sites that require high-capacity 50Hz, 3-phase electrical supply.

Powered by a Cummins QST30G4 diesel engine, the AC1100 uses a 12-cylinder, 30.48-litre, V-type diesel engine running at 1500rpm. The engine is turbocharged and low-temperature aftercooled, with direct fuel injection, ECM governor control, replaceable fuel, oil and dry element air filters, water cooling, radiator and fan assembly, and 12/24V DC starter and charge alternator system.

The generator is supplied with a brushless single-bearing alternator with revolving field design, 4-pole construction, 2/3 pitch stator, Class H insulation, self-excitation, self-regulation, solid-state automatic voltage regulation, and direct-drive centrifugal blower cooling. This helps provide stable output for large standby and prime power loads.

Control and protection are handled by the DSE7320 control panel, mounted on the genset base frame. The controller monitors generator voltage, current, frequency, engine oil pressure, coolant temperature, battery voltage, running hours, mains supply, operating status, alarms, and shutdown conditions. The unit is available in open or sound-attenuated canopy configuration for different installation requirements.
