Product Overview
The AKSA APD1650M is a high-capacity diesel generating set built for dependable standby and prime power use across commercial premises, industrial sites, infrastructure facilities, construction projects, agricultural operations, workshops, data centres, and critical backup power applications. It delivers 1650 kVA / 1320 kW standby power and 1500 kVA / 1200 kW prime power, making it suitable for installations that require stable 400/231V, 50Hz, 3-phase electrical supply.
Powered by a Mitsubishi S12R-PTAA2 diesel engine, the APD1650M uses a 12-cylinder, 49.03-litre, V-type diesel engine running at 1500rpm. The engine is turbocharged and aftercooled, with direct injection, electronic governor control, water cooling, dry-type air filtration, 24V DC electrical system, block heater support, and heavy-duty construction for large generator applications.
The generator is supplied with a Mecc Alte ECO 46-1S/4 A alternator rated at 1500 kVA. The alternator features brushless operation, Class H insulation, IP23 protection, DER1 automatic voltage regulator, 0.8 rated power factor, and ?0.5% voltage regulation to support stable electrical output for high-capacity standby and prime power loads.
Control and protection are handled by the DSE7320 control panel. The controller supports generator monitoring, automatic mains failure operation, operating status display, alarm indication, fault protection, and shutdown handling. The APD1650M is available in open or AK 99 sound-attenuated canopy configuration with external removable silencer depending on installation requirements.
