CUMMINS AC700 Diesel Generator – 50Hz

AKSA AC700 diesel generator set rated at 700 kVA / 560 kW standby and 638 kVA / 510.4 kW prime. Powered by a Cummins VTA28G5 diesel engine, this 400/230V, 50Hz, 3-phase generator is designed for reliable 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 AC700 is a heavy-duty diesel generating set built for dependable standby and prime power use across commercial, industrial, infrastructure, construction, agricultural, and backup power applications. It delivers 700 kVA / 560 kW standby power and 638 kVA / 510.4 kW prime power, making it suitable for sites that require high-capacity 50Hz, 3-phase electrical supply.

Powered by a Cummins VTA28G5 diesel engine, the AC700 uses a 12-cylinder, 28-litre, turbocharged and aftercooled diesel engine running at 1500rpm. The engine features direct fuel injection, electronic 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.
