CUMMINS AC1675 Diesel Generator – 50Hz

Product Overview

The AKSA AC1675 is a high-capacity diesel generating set designed for reliable standby and prime power applications. It delivers 1675 kVA / 1340 kW standby power and 1500 kVA / 1200 kW prime power at 400/230V, 50Hz, 3-phase output with 0.8 power factor.

Powered by a Cummins KTA50GS8 diesel engine, the AC1675 uses a 16-cylinder V-type, 50.3-litre, turbocharged and aftercooled engine running at 1500rpm. The engine features direct fuel injection, electronic governor control, water cooling, and heavy-duty diesel performance for demanding commercial and industrial environments.

The generator set includes a brushless, single-bearing alternator with Class H insulation, self-excited regulation, 2/3 pitch stator winding, and low harmonic distortion. The DSE 7320 control panel provides automatic mains failure operation, generator monitoring, alarm protection, LED indication, and push-button control for safe and practical operation.
